Comment on "Infrared freezing of Euclidean QCD observables"
|
Recently, P. M. Brooks and C.J. Maxwell [Phys. Rev. D{\bf 74} 065012 (2006)]
claimed that the Landau pole of the one-loop coupling at $Q^2=\Lambda^2$ is
absent from the leading one-chain term in a skeleton expansion of the Euclidean
Adler ${\cal D}$ function. Moreover, in this approximation one has continuity
along the Euclidean axis and a smooth infrared freezing, properties known to be
satisfied by the "true" Adler function. We show that crucial in the derivation
of these results is the use of a modified Borel summation, which leads
simultaneously to the loss of another fundamental property of the true Adler
function: the analyticity implied by the K\"allen-Lehmann representation.

Interplay between structure and density anomaly for an isotropic
core-softened ramp-like potential
|
Using molecular dynamics simulations and integral equations we investigate
the structure, the thermodynamics and the dynamics of a system of particles
interacting through a continuous core- softened ramp-like interparticle
potential. We found density, dynamic and structural anomalies similar to that
found in water. Analysis of the radial distribution function for several
temperatures at fixed densities show a pattern that may be related to the
origin of density anomaly.

Factor Two Discrepancy of Hawking Radiation Temperature
|
The possibility of an alternative way to formulate the Hawking radiation in a
static Schwarzschild spacetime has been explored. To calculate the Hawking
radiation, there can be two possible choices of the spacetime wedge pairs in
the Krucal-Szekeres coordinates. One is the wedge pair consists of exterior
spacetime of a black hole and the exterior spacetime of a white hole, and the
other is that of exterior and interior spacetimes of one black hole. The
radiation from the former is the Hawking's original one. Though the the latter
has been often regarded as the same phenomena as the former, the result here
suggests it is not; its radiation has a temperature twice as high as the
Hawking temperature.

A variational theory for point defects in patterns
|
We derive a rigorous scaling law for minimizers in a natural version of the
regularized Cross-Newell model for pattern formation far from threshold. These
energy-minimizing solutions support defects having the same character as what
is seen in experimental studies of the corresponding physical systems and in
numerical simulations of the microscopic equations that describe these systems.

The statistics of LCDM Halo Concentrations
|
We use the Millennium Simulation (MS) to study the statistics of LCDM halo
concentrations at z = 0. Our results confirm that the average halo
concentration declines monotonically with mass; a power-law fits well the
concentration-mass relation for over 3 decades in mass, up to the most massive
objects to form in a LCDM universe (~ 10^15 h^-1 Msol). This is in clear
disagreement with the predictions of the model proposed by Bullock et al. for
these rare objects, and agrees better with the original predictions of Navarro,
Frenk, & White. The large volume surveyed, together with the unprecedented
numerical resolution of the MS, allow us to estimate with confidence the
distribution of concentrations and, consequently, the abundance of systems with
unusual properties. About one in a hundred cluster haloes (M200 >~ 3x10^14 h^-1
Msol) have concentrations exceeding c200 = 7.5, a result that may be used to
interpret the likelihood of unusually strong massive gravitational lenses, such
as Abell 1689, in the LCDM cosmogony. A similar fraction (1 in 100) of
galaxy-sized haloes (M200 ~ 10^12 h^-1 Msol) have c200 < 4.5, an important
constraint on models that attempt to reconcile the rotation curves of low
surface-brightness galaxies by appealing to haloes of unexpectedly low
concentration. We find that halo concentrations are independent of spin once
haloes manifestly out of equilibrium are removed from the sample. Compared to
their relaxed brethren, the concentrations of out-of-equilibrium haloes tend to
be lower and to have more scatter, while their spins tend to be higher...

Tropical hyperplane arrangements and oriented matroids
|
We study the combinatorial properties of a tropical hyperplane arrangement.
We define tropical oriented matroids, and prove that they share many of the
properties of ordinary oriented matroids. We show that a tropical oriented
matroid determines a subdivision of a product of two simplices, and conjecture
that this correspondence is a bijection.

Mackey functors on compact closed categories
|
We develop and extend the theory of Mackey functors as an application of
enriched category theory. We define Mackey functors on a lextensive category
$\E$ and investigate the properties of the category of Mackey functors on $\E$.
We show that it is a monoidal category and the monoids are Green functors.
Mackey functors are seen as providing a setting in which mere numerical
equations occurring in the theory of groups can be given a structural
foundation. We obtain an explicit description of the objects of the Cauchy
completion of a monoidal functor and apply this to examine Morita equivalence
of Green functors.

Let g denote a Lie algebra, and let T(g) denote the tensor product of g with
a ring of truncated polynomials. The Lie algebra T(g) is called a truncated
current Lie algebra. The highest-weight representation theory of T(g) is
developed, and a reducibility criterion for the Verma modules is described.

A scaling relation of anomalous Hall effect in ferromagnetic
semiconductors and metals
|
A scaling relation of the anomalous Hall effect recently found in a
ferromagnetic semiconductor (Ti,Co)O_2_ is compared with those of various
ferromagnetic semiconductors and metals. Many of these compounds with
relatively low conductivity sigma_xx_ < 10^4 ohm^-1 cm^-1 are also found to
exhibit similar relation: anomalous Hall conductivity sigma_AH_ approximately
scales as sigma_AH_ proportional to sigma_xx_^1.6, that is coincident with a
recent theory. This relation is valid over five decades of sigma_xx_
irrespective of metallic or hopping conduction.

Non-Markovian dynamics in the theory of full counting statistics
|
We consider the theoretical description of real-time counting of electrons
tunneling through a Coulomb-blockade quantum dot using a detector with finite
bandwidth. By tracing out the quantum dot we find that the dynamics of the
detector effectively is non-Markovian. We calculate the cumulant generating
function corresponding to the resulting non-Markovian rate equation and find
that the measured current cumulants behave significantly differently compared
to those of a Markovian transport process. Our findings provide a novel
interpretation of noise suppression found in a number of systems.

We discuss how the loop calculus approach of [Chertkov, Chernyak '06],
enhanced by the pseudo-codeword search algorithm of [Chertkov, Stepanov '06]
and the facet-guessing idea from [Dimakis, Wainwright '06], improves decoding
of graph based codes in the error-floor domain. The utility of the new, Linear

Green's function approach to transport through a gate-all-around Si
nanowire under impurity scattering
|
We investigate transport properties of gate-all-around Si nanowires using
non-equilibrium Green's function technique. By taking into account of the
ionized impurity scattering we calculate Green's functions self-consistently
and examine the effects of ionized impurity scattering on electron densities
and currents. For nano-scale Si wires, it is found that, due to the impurity
scattering, the local density of state profiles loose it's interference
oscillations as well as is broaden and shifted. In addition, the impurity
scattering gives rise to a different transconductance as functions of
temperature and impurity scattering strength when compared with the
transconductance without impurity scattering.

Strong effect of weak diffusion on scalar turbulence at large scales
|
Passive scalar turbulence forced steadily is characterized by the velocity
correlation scale, $L$, injection scale, $l$, and diffusive scale, $r_d$. The
scales are well separated if the diffusivity is small, $r_d\ll l,L$, and one
normally says that effects of diffusion are confined to smaller scales, $r\ll
r_d$. However, if the velocity is single scale one finds that a weak dependence
of the scalar correlations on the molecular diffusivity persists to even larger
scales, e.g. $l\gg r\gg r_d$ \cite{95BCKL}. We consider the case of $L\gg l$
and report a counter-intuitive result -- the emergence of a new range of large
scales, $L\gg r\gg l^2/r_d$, where the diffusivity shows a strong effect on
scalar correlations.

Noncompact sigma-models: Large N expansion and thermodynamic limit
|
Noncompact SO(1,N) sigma-models are studied in terms of their large N
expansion in a lattice formulation in dimensions d \geq 2. Explicit results for
the spin and current two-point functions as well as for the Binder cumulant are
presented to next to leading order on a finite lattice. The dynamically
generated gap is negative and serves as a coupling-dependent infrared regulator
which vanishes in the limit of infinite lattice size. The cancellation of
infrared divergences in invariant correlation functions in this limit is
nontrivial and is in d=2 demonstrated by explicit computation for the above
quantities. For the Binder cumulant the thermodynamic limit is finite and is
given by 2/(N+1) in the order considered. Monte Carlo simulations suggest that
the remainder is small or zero. The potential implications for ``criticality''
and ``triviality'' of the theories in the SO(1,N) invariant sector are
discussed.

Strong magnetic field enhancement of spin triplet pairing arising from
coexisting $2k_F$ spin and $2k_F$ charge fluctuations
|
We study the effect of the magnetic field (Zeeman splitting) on the triplet
pairing. We show generally that the enhancement of spin triplet pairing
mediated by coexisting $2k_F$ spin and $2k_F$ charge fluctuations can be much
larger than in the case of triplet pairing mediated by ferromagnetic spin
fluctuations. We propose that this may be related to the recent experiment for
(TMTSF)$_2$ClO$_4$, in which a possibility of singlet to triplet pairing
transition has been suggested.

Markov Process of Muscle Motors
|
We study a Markov random process describing a muscle molecular motor
behavior. Every motor is either bound up with a thin filament or unbound. In
the bound state the motor creates a force proportional to its displacement from
the neutral position. In both states the motor spend an exponential time
depending on the state. The thin filament moves at its velocity proportional to
average of all displacements of all motors. We assume that the time which a
motor stays at the bound state does not depend on its displacement. Then one
can find an exact solution of a non-linear equation appearing in the limit of
infinite number of the motors.

The formation of the [alpha/Fe] radial gradients in the stars of
elliptical galaxies
|
The scope of this paper is two-fold: i) to test and improve our previous
models of an outside-in formation for the majority of ellipticals in the
context of the SN-driven wind scenario, by means of a careful study of gas
inflows/outflows; ii) to explain the observed slopes, either positive or
negative, in the radial gradient of the mean stellar [alpha/Fe], and their
apparent lack of any correlation with all the other observables. In order to
pursue these goals we present a new class of hydrodynamical simulations for the
formation of single elliptical galaxies in which we implement detailed
prescriptions for the chemical evolution of H, He, O and Fe. We find that all
the models which predict chemical properties (such as the central mass-weighted
abundance ratios, the colours as well as the [<Fe/H>] gradient) within the
observed ranges for a typical elliptical, also exhibit a variety of gradients
in the [<alpha/Fe>] ratio, in agreement with the observations (namely positive,
null or negative). All these models undergo an outside-in formation, in the
sense that star formation stops earlier in the outermost than in the innermost
regions, owing to the onset of a galactic wind. The typical [<Z/H>] gradients
predicted by our models have a slope of -0.3 dex per decade variation in
radius, consistent with the mean values of several observational samples. We
can safely conclude that the history of star formation is fundamental for the
creation of abundance gradients in ellipticals but that radial flows with
different velocity in conjunction with the duration and efficiency of star
formation in different galactic regions are responsible for the gradients in
the [<alpha/Fe>] ratios.

Electromagnetic quasinormal modes of D-dimensional black holes II
|
By using the sixth order WKB approximation we calculate for an
electromagnetic field propagating in D-dimensional Schwarzschild and
Schwarzschild de Sitter black holes its quasinormal frequencies for the
fundamental mode and first overtones. We study the dependence of these QN
frequencies on the value of the cosmological constant and the spacetime
dimension. We also compare with the known results for the gravitational
perturbations propagating in the same background. Moreover we exactly compute
the QN frequencies of the electromagnetic field propagating in D-dimensional
massless topological black hole and for charged D-dimensional Nariai spacetime
we exactly calculate the QN frequencies of the coupled electromagnetic and
gravitational perturbations.

Recent heavy flavor results from STAR
|
We report on recent heavy flavor measurements from the STAR experiment at
RHIC. The measured charm cross section in heavy-ion collisions scales with the
number of binary collisions, which is an indication for exclusive charm
production in the initial state of the collision. The observed strong
suppression of non-photonic electrons at high $\pt$ in Au+Au collisions
together with the azimuthal correlation measurements in p+p collisions imply a
suppression of $B$ production in heavy-ion collisions. We also present recent
measurements of the $\Upsilon$ cross section in p+p collisions.

Preferential attachment during the evolution of a potential energy
landscape
|
It has previously been shown that the network of connected minima on a
potential energy landscape is scale-free, and that this reflects a power-law
distribution for the areas of the basins of attraction surrounding the minima.
Here, we set out to understand more about the physical origins of these
puzzling properties by examining how the potential energy landscape of a
13-atom cluster evolves with the range of the potential. In particular, on
decreasing the range of the potential the number of stationary points increases
and thus the landscape becomes rougher and the network gets larger. Thus, we
are able to follow the evolution of the potential energy landscape from one
with just a single minimum to a complex landscape with many minima and a
scale-free pattern of connections. We find that during this growth process, new
edges in the network of connected minima preferentially attach to more
highly-connected minima, thus leading to the scale-free character. Furthermore,
minima that appear when the range of the potential is shorter and the network
is larger have smaller basins of attraction. As there are many of these smaller
basins because the network grows exponentially, the observed growth process
thus also gives rise to a power-law distribution for the hyperareas of the
basins.

High-Resolution Spectra Observed for SPY. II. DB and DBA Stars
|
We present a detailed spectroscopic analysis of the stars with
helium-dominated spectra in the ESO Supernova Ia Progenitor Survey (SPY).
Atmospheric parameters, masses, and abundances of trace hydrogen are determined
and discussed in the context of spectral evolution of white dwarfs. Our final
sample contains 71 objects, of which 6 are new detections and 14 are
reclassified from DB to DBA because of the presence of H lines. 55% of the DB
sample show hydrogen and are thus DBA, a significantly higher fraction than
found before. The large incidence of DBA, and the derived total hydrogen masses
are compatible with the scenario that DBs ``reappear'' around 30000 K from the
DB gap by mixing and diluting a thin hydrogen layer of the order of E-15 Msun.
This hydrogen mass is then during the evolution continuously increased by
interstellar accretion. There are indications that the accretion rate increases
smoothly with age or decreasing temperature, a trend which continuous even
below the current low temperature limit (Dufour 2006). A remaining mystery is
the low accretion rate of H compared to that of Ca observed in the DBZA, but a
stellar wind extending down to the lowest temperatures with decreasing strength
might be part of the solution.

On the dependence of the wave function of a bound nucleon on its
momentum and the EMC effect
|
It is widely discussed in the literature that the wave function of the
nucleon bound in a nucleus is modified due to the interaction with the
surrounding medium. We argue that the modification should strongly depend on
the momentum of the nucleon. We study such an effect in the case of the
point-like configuration component of the wave function of a nucleon bound in a
nucleus A, considering the case of arbitrary final state of the spectator A-1
system. We show that for non relativistic values of the nucleon momentum, the
momentum dependence of the nucleon deformation appears to follow from rather
general considerations and discuss the implications of our theoretical
observation for two different phenomena: i) the search for medium induced
modifications of the nucleon radius of a bound nucleon through the measurement
of the electromagnetic nucleon form factors via the A(e,e'p)X process, and ii)
the A-dependence of the EMC effect; in this latter case we also present a new
method of estimating the fraction of the nucleus light-cone momentum carried by
the photons and find that in a heavy nuclei protons loose about 2% of their
momentum.

A Common Origin for Quasar Extended Emission-Line Regions and Their
Broad-Line Regions
|
We present a correlation between the presence of luminous extended
emission-line regions (EELRs) and the metallicity of the broad-line regions
(BLRs) of low-redshift quasars. The result is based on ground-based [O III]
5007 narrow-band imaging and Hubble Space Telescope UV spectra of 12 quasars at
0.20 < z < 0.45. Quasars showing luminous EELRs have low-metallicity BLRs (Z <
0.6 Z_Solar), while the remaining quasars show typical metal-rich gas (Z >
Z_Solar). Previous studies have shown that EELRs themselves also have low
metallicities (Z < 0.5 Z_Solar). The correlation between the occurrence of
EELRs and the metallicity of the BLRs, strengthened by the sub-Solar
metallicity in both regions, indicates a common external origin for the gas,
almost certainly from the merger of a gas-rich galaxy. Our results provide the
first direct observational evidence that the gas from a merger can indeed be
driven down to the immediate vicinity (< 1 pc) of the central black hole.

Astrometric effects of solar-like magnetic activity in late-type stars
and their relevance for the detection of extrasolar planets
|
Using a simple model based on the characteristics of sunspots and faculae in
solar active regions, the effects of surface brightness inhomogeneities on the
position of the photocentre of the disk of a solar-like, magnetically active
star, are studied. A general law is introduced, giving the maximum amplitude of
the photocentre excursion produced by a distribution of active regions with a
given surface filling factor. The consequences for the detection of extrasolar
planets by means of the astrometric method are investigated with some
applications to forthcoming space missions, such as GAIA and SIM, as well as to
ground-based interferometric measurements. Spurious detections of extrasolar
planets can indeed be caused by activity-induced photocentre oscillations,
requiring a simultaneous monitoring of the optical flux and a determination of
the rotation period and of the level of activity of the target stars for an
appropriate discrimination.

Kondo physics in the algebraic spin liquid
|
We study Kondo physics in the algebraic spin liquid, recently proposed to
describe $ZnCu_{3}(OH)_{6}Cl_{2}$ [Phys. Rev. Lett. {\bf 98}, 117205 (2007)].
Although spin dynamics of the algebraic spin liquid is described by massless
Dirac fermions, this problem differs from the Pseudogap Kondo model, because
the bulk physics in the algebraic spin liquid is governed by an interacting
fixed point where well-defined quasiparticle excitations are not allowed.
Considering an effective bulk model characterized by an anomalous critical
exponent, we derive an effective impurity action in the slave-boson context.
Performing the large-$N_{\sigma}$ analysis with a spin index $N_{\sigma}$, we
find an impurity quantum phase transition from a decoupled local-moment state
to a Kondo-screened phase. We evaluate the impurity spin susceptibility and
specific heat coefficient at zero temperature, and find that such responses
follow power-law dependencies due to the anomalous exponent of the algebraic
spin liquid. Our main finding is that the Wilson's ratio for the magnetic
impurity depends strongly on the critical exponent in the zero temperature
limit. We propose that the Wilson's ratio for the magnetic impurity may be one
possible probe to reveal criticality of the bulk system.

Summing Pomeron loops in the dipole approach
|
In this paper we argue that in the kinematic range given by $ 1 \ll
\ln(1/\as^2) \ll \as Y \ll \frac{1}{\as}$, we can reduce the Pomeron calculus
to the exchange of non-interacting Pomerons with the renormalized amplitude of
their interaction with the target. Therefore, the summation of the Pomeron
loops can be performed using the improved Mueller, Patel, Salam and Iancu
approximation and this leads to the geometrical scaling solution. This solution
is found for the simplified BFKL kernel. We reproduce the findings of Hatta and
Mueller that there are overlapping singularities. We suggest a way of dealing
with these singularities.

Atom capture by nanotube and scaling anomaly
|
The existence of bound state of the polarizable neutral atom in the inverse
square potential created by the electric field of single walled charged carbon
nanotube (SWNT) is shown to be theoretically possible. The consideration of
inequivalent boundary conditions due to self-adjoint extensions lead to this
nontrivial bound state solution. It is also shown that the scaling anomaly is
responsible for the existence of bound state. Binding of the polarizable atoms
in the coupling constant interval \eta^2\in[0,1) may be responsible for the
smearing of the edge of steps in quantized conductance, which has not been
considered so far in literature.

An Obstruction to Quantization of the Sphere
|
In the standard example of strict deformation quantization of the symplectic
sphere $S^2$, the set of allowed values of the quantization parameter $\hbar$
is not connected; indeed, it is almost discrete. Li recently constructed a
class of examples (including $S^2$) in which $\hbar$ can take any value in an
interval, but these examples are badly behaved. Here, I identify a natural
additional axiom for strict deformation quantization and prove that it implies
that the parameter set for quantizing $S^2$ is never connected.

Do local analogs of Lyman Break Galaxies exist?
|
The optical properties of a number of supercompact ultraviolet luminous
galaxies (UVLG), recently discovered in the local Universe matching GALEX and
Sloan Digital Sky Survey (SDSS) data, are discussed. Detailed re-analysis of
the SDSS data for these and other similar but nearer galaxies shows that their
surface brightness radial profile in both R and u bands is in most cases well
described by an extended disk plus a central unresolved component (possibly a
bulge). Since the SDSS pipeline used a single disk component to derive the half
light radius of these UVLGs their size was severely underestimated.
Consequently, the average UV surface brightness is much lower that previously
quoted casting doubts on the claim that UVLGs are the local analogs of high
redshift Lyman break galaxies.

AGN effect on cooling flow dynamics
|
We analyzed the feedback of AGN jets on cooling flow clusters using
three-dimensional AMR hydrodynamic simulations. We studied the interaction of
the jet with the intracluster medium and creation of low X-ray emission
cavities (Bubbles) in cluster plasma. The distribution of energy input by the
jet into the system was quantified in its different forms, i.e. internal,
kinetic and potential. We find that the energy associated with the bubbles, (pV
+ gamma pV/(gamma-1)), accounts for less than 10 percent of the jet energy.

Electron Bunching in Stacks of Coupled Quantum Dots
|
We study the transport properties of two double quantum dots in a parallel
arrangement at temperatures of a few Kelvin. Thereby, we show that decoherence
entailed by the substrate phonons affects the shot noise. For asymmetric
coupling between the dots and the respective lead, the current noise is
sub-Poissonian for resonant tunneling, but super-Poissonian in the vicinity of
the resonances. Our results indicate that phonon emission and absorption is
responsible for the shot noise enhancement. The observed asymmetry of the peaks
at low temperatures stems from spontaneous emission.

Collinear versus non-collinear magnetic order in Pd atomic clusters:
ab-initio calculations
|
We present a thorough theoretical assessment of the stability of
non-collinear spin arrangements in small palladium clusters. We generally find
that ferromagnetic order is always preferred, but that antiferromagnetic and
non-collinear configurations of different sorts exist and compete for the first
excited isomers. We also show that the ground state is insensitive to the
choice of atomic configuration for the pseudopotential used and to the
approximation taken for the exchange and correlation potential. Moreover, the
existence and relative stability of the different excited configurations also
depends weakly on the approximations employed. These results provide strong
evidence on the transferability of pseudopotential and exchange and correlation
functionals for palladium clusters as opposed to the situation found for the
bulk phases of palladium.

we present a thorough theoretical assessment of the stability of noncollinear spin arrangements in small palladium clusters we generally find that ferromagnetic order is always preferred but that antiferromagnetic and noncollinear configurations of different sorts exist and compete for the first excited isomers we also show that the ground state is insensitive to the choice of atomic configuration for the pseudopotential used and to the approximation taken for the exchange and correlation potential moreover the existence and relative stability of the different excited configurations also depends weakly on the approximations employed these results provide strong evidence on the transferability of pseudopotential and exchange and correlation functionals for palladium clusters as opposed to the situation found for the bulk phases of palladium

Mass distributions for nuclear disintegration from fission to
evaporation
|
By a proper choice of the excitation energy per nucleon we analyze the mass
distributions of the nuclear fragmentation at various excitation energies.
Starting from low energies (between 0.1 and 1 MeV/nucleon) up to higher
energies about 12 MeV/n, we classified the mass yield characteristics for heavy
nuclei (A>200) on the basis of Statistical Multifragmentation Model. The
evaluation of fragment distribution with the excitation energy show that the
present results exhibit the same trend as the experimental ones.

Running of $\alpha_s$ and $m_b$ in the MSSM
|
A consistent evolution of the strong coupling constant $\alpha_s$ from $M_Z$
to the GUT scale is presented, involving three-loop running and two-loop
decoupling. The two-loop transition from the MS- to the DR-scheme is properly
taken into account. In the second part of the paper, the bottom quark mass in
the DR-scheme at the electroweak/SUSY scale is evaluated with four-loop
accuracy. We find that the three-loop effects are comparable to the
experimental uncertainty both for $\alpha_s$ and $m_b$.

Ergodicity properties of quantum expectation values in entangled states
|
Using a model Hamiltonian for a single-mode electromagnetic field interacting
with a nonlinear medium, we show that quantum expectation values of subsystem
observables can exhibit remarkably diverse ergodic properties even when the
dynamics of the total system is regular. The time series of the mean photon
number is studied over a range of values of the ratio of the strength $\gamma$
of the nonlinearity to that of the inter-mode coupling $g$. We obtain the power
spectrum, estimate the embedding dimension of the reconstructed phase space and
the maximal Liapunov exponent $\lambda_{\rm max}$, and find the recurrence-time
distribution of the coarse-grained dynamics. The dynamical behavior ranges from
quasiperiodicity (for $\gamma/g \ll 1$) to chaos as characterized by
$\lambda_{\rm max} > 0$ (for $\gamma/g \gtrsim 1$), and is interpreted.

using a model hamiltonian for a singlemode electromagnetic field interacting with a nonlinear medium we show that quantum expectation values of subsystem observables can exhibit remarkably diverse ergodic properties even when the dynamics of the total system is regular the time series of the mean photon number is studied over a range of values of the ratio of the strength gamma of the nonlinearity to that of the intermode coupling g we obtain the power spectrum estimate the embedding dimension of the reconstructed phase space and the maximal liapunov exponent lambda_rm max and find the recurrencetime distribution of the coarsegrained dynamics the dynamical behavior ranges from quasiperiodicity for gammag ll 1 to chaos as characterized by lambda_rm max 0 for gammag gtrsim 1 and is interpreted

Density-dependent interactions and structure of charged colloidal
dispersions in the weak screening regime
|
We determine the structure of charge-stabilized colloidal suspensions at low
ionic strength over an extended range of particle volume fractions using a
combination of light and small angle neutron scattering experiments. The
variation of the structure factor with concentration is analyzed within a
one-component model of a colloidal suspension. We show that the observed
structural behavior corresponds to a non-monotonic density dependence of the
colloid effective charge and the mean interparticle interaction energy. Our
findings are corroborated by similar observations from primitive model computer
simulations of salt-free colloidal suspensions.

Reply to Comment on "A local realist model for correlations of the
singlet state"
|
The general conclusion of Seevinck and Larsson is that our model exploits the
so-called coincidence-time loophole and produces sinusoidal (quantum-like)
correlations but does not model the singlet state because it does not violate
the relevant Bell inequality derived by Larsson and Gill, since in order to
obtain the sinusoidal correlations the probability of coincidences in our model
goes to zero. In this reply, we refute their arguments that lead to this
conclusion and demonstrate that our model can reproduce results of photon and
ion-trap experiments with frequencies of coincidences that are not in conflict
with the observations.

On the shadow boundary of a centrally symmetric convex body
|
We discuss the concept of the shadow boundary of a centrally symmetric convex
ball $K$ (actually being the unit ball of a Minkowski normed space) with
respect to a direction ${\bf x}$ of the Euclidean n-space $R^n$. We introduce
the concept of general parameter spheres of $K$ corresponding to this direction
and prove that the shadow boundary is a topological manifold if all of the
non-degenerated general parameter spheres are, too. In this case, using the
approximation theorem of cell-like maps we get that they are homeomorphic to
the $(n-2)$-dimensional sphere $S^{(n-2)}$. We also prove that the bisector
(equidistant set of the corresponding normed space) in the direction ${\bf x}$
is homeomorphic to $R^{(n-1)}$ iff all of the non-degenerated general parameter
spheres are $(n-2)$-manifolds implying that if the bisector is a homeomorphic
copy of $R^{(n-1)}$ then the corresponding shadow boundary is a topological
$(n-2)$-sphere.

The variability plane of accreting compact objects
|
Recently, it has been shown that soft-state black hole X-ray binaries and
active galactic nuclei populate a plane in the space defined by the black hole
mass, accretion rate and characteristic frequency. We show that this plane can
be extended to hard-state objects if one allows a constant offset for the
frequencies in the soft and the hard state. During a state transition the
frequencies rapidly move from one scaling to the other depending on an
additional parameter, possibly the disk-fraction. The relationship between
frequency, mass and accretion rate can be further extended by including weakly
accreting neutron stars. We explore if the lower kHz QPOs of neutron stars and
the dwarf nova oscillations of white dwarfs can be included as well and discuss
the physical implications of the found correlation.

Constraints on top-down models for the origin of UHECRs from the Pierre
Auger Observatory data
|
Taking into account the Pierre Auger Observatory limits on the photon
fraction among the highest energy cosmic rays, we show that the models based on
the decay of super-heavy dark matter in the halo of our Galaxy are essentially
excluded from being the sources of UHECRs unless their contribution becomes
significant only above 100 EeV. Some top-down models based on topological
defects are however compatible with the current data and may be best
constrained in the future by the high-energy neutrino flux limit.

Structure of glassy lithium sulfate films sputtered in nitrogen (LISON):
Insight from Raman spectroscopy and ab initio calculations
|
Raman spectra of thin solid electrolyte films obtained by sputtering a
lithium sulfate target in nitrogen plasma are measured and compared to ab
initio electronic structure calculations for clusters composed of 28 atoms.
Agreement between measured and calculated spectra is obtained when oxygen atoms
are replaced by nitrogen atoms and when the nitrogen atoms form bonds with each
other. This suggests that the incorporation of nitrogen during the sputtering
process leads to structures in the film, which prevent crystallization of these
thin film salt glasses.

Variable stars in the open cluster NGC 6791 and its surrounding field
|
Aims: This work presents a high--precision variability survey in the field of
the old, super metal-rich open cluster NGC 6791.
Methods: The data sample consists of more than 75,000 high-precision CCD time
series measurements in the V band obtained mainly at the Canada-France-Hawaii
Telescope, with additional data from S. Pedro Martir and Loiano observatories,
over a time span of ten nights. The field covers an area of 42x28 arcmin^2.
Results: We have discovered 260 new variables and re-determined periods and
amplitudes of 70 known variable stars. By means of a photometric evaluation of
the membership in NGC 6791, and a preliminary membership based on the proper
motions, we give a full description of the variable content of the cluster and
surrounding field in the range 16<V<23.5. Accurate periods can be given for the
variables with P<4.0 d, while for ones with longer periods the limited
time-baseline hampered precise determinations. We categorized the entire sample
as follows: 6 pulsating, 3 irregular, 3 cataclysmic, 89 rotational variables
and 61 eclipsing systems; moreover, we detected 168 candidate variables for
which we cannot give a variability class since their periods are much longer
than our time baseline.
Conclusions: On the basis of photometric considerations, and of the positions
of the stars with respect to the center of the cluster, we inferred that 11 new
variable stars are likely members of the cluster, for 22 stars the membership
is doubtful and 137 are likely non-members. We also detected an outburst of
about 3 mag in the light curve of a very faint blue star belonging to the
cluster and we suggest that this star could be a new U Gem (dwarf nova)
cataclysmic variable.

Outage Behavior of Discrete Memoryless Channels Under Channel Estimation
Errors
|
Classically, communication systems are designed assuming perfect channel
state information at the receiver and/or transmitter. However, in many
practical situations, only an estimate of the channel is available that differs
from the true channel. We address this channel mismatch scenario by using the
notion of estimation-induced outage capacity, for which we provide an
associated coding theorem and its strong converse, assuming a discrete
memoryless channel. We illustrate our ideas via numerical simulations for
transmissions over Ricean fading channels under a quality of service (QoS)
constraint using rate-limited feedback channel and maximum likelihood (ML)
channel estimation. Our results provide intuitive insights on the impact of the
channel estimate and the channel characteristics (SNR, Ricean K-factor,
training sequence length, feedback rate, etc.) on the mean outage capacity.

Local models and EPR quantum correlations
|
A model for two entangled systems in an EPR setting is shown to reproduce the
quantum-mechanical outcomes and expectation values. Each system is represented
by a small sphere containing a point-like particle embedded in a field. A
quantum state appears as an equivalence class of several possible
particle-field configurations. Contrarily to Bell-type hidden variables models,
the fields account for the non-commutative aspects of the measurements and deny
the simultaneous reality of incompatible physical quantities, thereby allowing
to escape EPR's ``completeness or locality'' dilemma.

The two Josephson junction flux qubit with large tunneling amplitude
|
In this paper we discuss solid-state nanoelectronic realizations of Josephson
flux qubits with large tunneling amplitude between the two macroscopic states.
The latter can be controlled via the height and wells form of the potential
barrier, which is determined by quantum-state engineering of the flux qubit
circuit. The simplest circuit of the flux qubit is a superconducting loop
interrupted by a Josephson nanoscale tunnel junction. The tunneling amplitude
between two macroscopically different states can be essentially increased, by
engineering of the qubit circuit, if tunnel junction is replaced by a ScS
contact. However, only Josephson tunnel junctions are particularly suitable for
large-scale integration circuits and quantum detectors with preset-day
technology. To overcome this difficulty we consider here the flux qubit with
high-level energy separation between "ground" and "excited" states, which
consists of a superconducting loop with two low-capacitance Josephson tunnel
junctions in series. We demonstrate that for real parameters of resonant
superposition between the two macroscopic states the tunneling amplitude can
reach values greater than 1K. Analytical results for the tunneling amplitude
obtained within semiclassical approximation by instanton technique show good
correlation with a numerical solution.

Surface melting of nanoscopic epitaxial films
|
By introducing finite size surface and interfacial excess quantities,
interactions between interfaces are shown to modify the usual surface
premelting phenomenon. It is the case of surface melting of a thin solid film s
deposited on a planar solid substrate S. More precisely to the usual wetting
condition of the solid s by its own melt l, necessary for premelting (wetting
factor F<0), is adjoined a new quantity G describing the interactions of the
l/s interface with the s/S interface. When G>0 this interface attraction boosts
the premelting so that a two stage boosted surface premelting is foreseen: a
continuous premelting, up to roughly half the deposited film, is followed by an
abrupt first order premelting. When G<0 these interfaces repell each other so
that premelting is refrained and the film remains partly solid above the bulk
melting point (overheating) what is called astride melting. Elastic stress
modifies both types of melting curves. Bulk and surface stresses have to be
distinguished.

Terahertz Parametric Gain in Semiconductor Superlattices
|
We consider a high-frequency response of electrons in a single miniband of
superlattice subject to dc and ac electric fields. Action of ac electric field
causes oscillations of electron's effective mass in miniband, which result in a
parametric resonance. We have established a theoretical feasibility of
phase-sensitive parametric amplification at the resonance. The parametric
amplification does not require operation in conditions of negative differential
conductance. Therefore a formation of destructive domains of high electric
field inside the superlattice can be prevented. Here we concentrate on the
parametric up- and down-conversion of electromagnetic radiation from available
frequencies to desirable THz frequency range.

Random resistor network model of minimal conductivity in graphene
|
Transport in undoped graphene is related to percolating current patterns in
the networks of {\em N-} and {\em P}-type regions reflecting the strong bipolar
charge density fluctuations. Transmissions of the {\em P-N} junctions, though
small, are vital in establishing the macroscopic conductivity. We propose a
random resistor network model to analyze scaling dependencies of the
conductance on the doping and disorder, the quantum magnetoresistance and the
corresponding dephasing rate.

Optical spectroscopy of RU Cam, a pulsating carbon star
|
We analysed the high resolution spectra of a RU Cam, classified as W Vir type
star. The atmospheric parameters of RU Cam were estimated Teff=5250K and log
g=1.0. The hydrogen deficiency of RU Cam was not confirmed. The iron abundance,
[Fe/H]=-0.37, is close to the solar one. Abundances of most other elements are
also close to normal. We found considerable excesses of carbon and nitrogen:
[C/Fe]=+0.98, [N/Fe]=+0.60. The carbon to oxygen ratio is C/O$\ge$1. The carbon
isotopic abundance ratio is equal to C^12/C^13=4.5. For sodium a moderate
overabundance Na/Fe=+0.55 was obtained. For two moments of observations we
found close heliocentric velocity values, Vr=-21.7+/-0.8 and -23.1+/-1.0 km/s.
Both spectra contain a peculiar feature - an emission component of NaI doublet
which location agrees with the radial velocity from the bulk of metallic lines.
For our two observing moments we found no dependence of radial velocities on
the formation depth or on excitation energy for metallic lines.

On Scattering for CMV Matrices
|
Adamjan-Arov (Lax--Phillips) model space is considered as a scattering
representation space for a CMV matrix in context of an extended
Marchenko--Faddeev scattering theory. That is, there exists a basis in which
the multiplication by independent variable is a CMV matrix. This basis as well
as Verblunski coefficients are computed explicitly in terms of Nehari
interpolation. Asymptotically the Verblynski coefficients go to zero. Moreover,
relations between the basis and wandering subspaces are established.
Transformation from scattering representation to spectral representation is
given.

Entropy profiles in X-ray luminous galaxy clusters at z>0.1
|
[Abridged] The entropy distribution of the intracluster gas reflects both
accretion history of the gas and processes of feedback which provide a further
non-gravitational energy besides the potential one. In this work, we study the
profiles and the scaling properties of the gas entropy in 24 hot (kT_{gas} > 6
keV) galaxy clusters observed with Chandra in the redshift range 0.14-0.82 and
showing different states of relaxation. We recover the gas density, temperature
and entropy profiles in a non-parametric way. Adding the hydrostatic
equilibrium hypothesis, radial profiles are also obtained from the deprojection
of the surface brightness, allowing to verify whether the hydrostatic
equilibrium is a tenable hypothesis by comparison with the spectral
measurements. We confirm that this is the case on scales larger than 100 kpc
and discuss the deviations observed in few non-cooling core clusters in the
inner regions. We show that the entropy profiles are remarkably similar outside
the core and can be described by simple power-laws with slope of 1.0-1.2. We
measure an entropy level at 0.1 R_{200} of 100-500 keV cm^2 and a central
plateau which spans a wide range of value (~ a few-200 keV cm^2) depending on
the state of relaxation of the source. To characterize the energetic of the
central regions, we compare the radial behaviour of the temperature of the gas
with the temperature of the dark matter T_{DM} by estimating the excess of
energy Delta E = 3/2 k(T_{gas}- T_{DM}). We point out that Delta E ranges from
~ 0 in typical cooling-core clusters to few keV within 100 kpc in non-cooling
core systems. We also measure a significant correlation between the total iron
mass and the entropy outside the cooling region,whereas in the inner regions
they anti-correlate strongly.

Electron-positron annihilation into phi f_{0}(980) and clues for a new
1^{--} resonance
|
We study the e^{+}e^{-} to phi pi pi reaction for pions in an isoscalar
s-wave which is dominated by loop mechanisms. For kaon loops we start from the
conventional RCHPT, but use the unitarized amplitude for KbarK-pipi scattering
and the full kaon form factor instead of the lowest order terms. We study also
effects of vector mesons using RCHPT supplemented with the conventional
anomalous term for VVP interactions and taking into account the effects of
heavy vector mesons in the K*K transition form factor. We find a peak in the
dipion invariant mass around the f_{0}(980) as in the experiment. Selecting the
phi f_{0}(980) contribution as a function of the e^{+}e^{-} energy we also
reproduce the experimental data except for a narrow peak, yielding support to
the existence of a 1^{--} resonance above the phi f_{0}(980) threshold,
coupling strongly to this state.

Nontrivial critical crossover between directed percolation models:
Effect of infinitely many absorbing states
|
At non-equilibrium phase transitions into absorbing (trapped) states, it is
well known that the directed percolation (DP) critical scaling is shared by two
classes of models with a single (S) absorbing state and with infinitely many
(IM) absorbing states. We study the crossover behavior in one dimension,
arising from a considerable reduction of the number of absorbing states
(typically from the IM-type to the S-type DP models), by following two
different (excitatory or inhibitory) routes which make the auxiliary field
density abruptly jump at the crossover. Along the excitatory route, the system
becomes overly activated even for an infinitesimal perturbation and its
crossover becomes discontinuous. Along the inhibitory route, we find continuous
crossover with the universal crossover exponent $\phi\simeq 1.78(6)$, which is
argued to be equal to $\nu_\|$, the relaxation time exponent of the DP
universality class on a general footing. This conjecture is also confirmed in
the case of the directed Ising (parity-conserving) class. Finally, we discuss
the effect of diffusion to the IM-type models and suggest an argument why
diffusive models with some hybrid-type reactions should belong to the DP class.

Remote laboratories: new technology and standard based architecture
|
E-Laboratories are important components of e- learning environments,
especially in scientific and technical disciplines. First widespread E-Labs
consisted in proposing simulations of real systems (virtual labs), as building
remote labs (remote control of real systems) was difficult by lack of
industrial standards and common protocols. Nowadays, robotics and automation
technologies make easier the interfacing of systems with computers. In this
frame, many researchers (such as those mentioned in [1]) focus on how to set up
such a remote control. But, only a few of them deal with the educational point
of view of the problem. This paper outlines our current research and reflection
about remote laboratory modelling.

U_{PMNS} = U_ell^dagger U_nu
|
We consider corrections to vanishing U_{e3} and maximal atmospheric neutrino
mixing originating from the relation U = U_ell^dagger U_nu, where U is the PMNS
mixing matrix and U_ell (U_nu) is associated with the diagonalization of the
charged lepton (neutrino) mass matrix. We assume that in the limit of U_ell or
U_nu being the unit matrix, one has U_{e3} = 0 and theta_{23} = pi/4, while the
solar neutrino mixing angle is a free parameter. Well-known special cases of
the indicated scenario are the bimaximal and tri-bimaximal mixing schemes. If
U_{e3} \neq 0 and theta_{23} \neq pi/4 due to corrections from the charged
leptons, |U_{e3}| can be sizable (close to the existing upper limit) and we
find that the value of the solar neutrino mixing angle is linked to the
magnitude of CP violation in neutrino oscillations. In the alternative case of
the neutrino sector correcting U_{e3} = 0 and theta_{23} = pi/4, we obtain a
generically smaller |U_{e3}| than in the first case. Now the magnitude of CP
violation in neutrino oscillations is connected to the value of the atmospheric
neutrino mixing angle theta_{23}. We find that both cases are in agreement with
present observations. We also introduce parametrization independent "sum-rules"
for the oscillation parameters.

The Interaction Of Multiple Convection Zones In A-type Stars
|
A-type stars have a complex internal structure with the possibility of
multiple convection zones. If not sufficiently separated, such zones will
interact through the convectively stable regions that lie between them. It is
therefore of interest to ask whether the typical conditions that exist within
such stars are such that these convections zones can ever be considered as
disjoint.
In this paper we present results from numerical simulations that help in
understanding how increasing the distance between the convectively unstable
regions are likely to interact through the stable region that separates them.
This has profound implications for mixing and transport within these stars.

Rational formality of function spaces
|
Let $X$ be a nilpotent space such that there exists $N\geq 1$ with
$H^N(X,\mathbb Q) \ne 0$ and $H^n(X,\mathbb Q)=0$ if $n>N$. Let $Y$ be a
m-connected space with $m\geq N+1$ and $H^*(Y,\mathbb Q)$ is finitely generated
as algebra. We assume that the odd part of the rational Hurewicz homomorphism:
$\pi_{odd}(X)\otimes \mathbb Q\to H_{odd}(X,\mathbb Q)$ is non-zero. We prove
that if the space $\mathcal F(X,Y)$ of continuous maps from $X$ to $Y$ is
rationally formal, then $Y$ has the rational homotopy type of a finite product
of Eilenberg Mac Lane spaces. At the opposite, we exhibit an example of a
rationally formal space $\mathcal F(S^2,Y)$ where $Y$ is not rationally
equivalent to a product of Eilenberg Mac Lane spaces.

Quantum and semiclassical phase functions for the quantization of
symmetric oscillators
|
We investigate symmetric oscillators, and in particular their quantization,
by employing semiclassical and quantum phase functions introduced in the
context of Liouville-Green transformations of the Schr\"{o}dinger equation. For
anharmonic oscillators, first order semiclassical quantization is seldom
accurate and the higher order expansions eventually break down given the
asymptotic nature of the series. A quantum phase that allows in principle to
retrieve the exact quantum mechanical quantization condition and wavefunctions
is given along with an iterative scheme to compute it. The arbitrariness
surrounding quantum phase functions is lifted by supplementing the phase with
boundary conditions involving high order semiclassical expansions. This allows
to extend the definition of oscillation numbers, that determine the
quantization of the harmonic oscillator, to the anharmonic case. Several
illustrations involving homogeneous as well as coupling constant dependant
anharmonic oscillators are given.

Security problems with a SC-CNN-based Chaotic Masking Secure
Communication System
|
This paper studies the security of a chaotic cryptosystem based on the Chua
circuit and implemented with State Controlled Cellular Neural Networks. It is
shown that the plaintext can be retrieved by ciphertext band-pass filtering
after an imperfect decoding with wrong receiver parameters. It is also shown
that the key space of the system can be notably reduced easing a brute force
attack. The system parameters were determined with high precision through the
analysis of the decoding error produced by the mismatch between receiver and
transmitter parameters.

Kinetics of cell division in epidermal maintenance
|
The rules governing cell division and differentiation are central to
understanding the mechanisms of development, aging and cancer. By utilising
inducible genetic labelling, recent studies have shown that the clonal
population in transgenic mouse epidermis can be tracked in vivo. Drawing on
these results, we explain how clonal fate data may be used to infer the rules
of cell division and differentiation underlying the maintenance of adult murine
tail-skin. We show that the rates of cell division and differentiation may be
evaluated by considering the long-time and short-time clone fate data, and that
the data is consistent with cells dividing independently rather than
synchronously. Motivated by these findings, we consider a mechanism for cancer
onset based closely on the model for normal adult skin. By analysing the
expected changes to clonal fate in cancer emerging from a simple two-stage
mutation, we propose that clonal fate data may provide a novel method for
studying the earliest stages of the disease.

Real Forms of Complex Higher Spin Field Equations and New Exact
Solutions

We formulate four dimensional higher spin gauge theories in spacetimes with
signature (4-p,p) and nonvanishing cosmological constant. Among them are chiral
models in Euclidean (4,0) and Kleinian (2,2) signature involving half-flat
gauge fields. Apart from the maximally symmetric solutions, including de Sitter
spacetime, we find: (a) SO(4-p,p) invariant deformations, depending on a
continuous and infinitely many discrete parameters, including a degenerate
metric of rank one; (b) non-maximally symmetric solutions with vanishing Weyl
tensors and higher spin gauge fields, that differ from the maximally symmetric
solutions in the auxiliary field sector; and (c) solutions of the chiral models
furnishing higher spin generalizations of Type D gravitational instantons, with
an infinite tower of Weyl tensors proportional to totally symmetric products of
two principal spinors. These are apparently the first exact 4D solutions with
non-vanishing massless higher spin fields.

QED collinear radiation factors in the next-to-leading logarithmic
approximation
|
The effect of the collinear photon radiation by charged particles is
considered in the second order of the perturbation theory. Double and single
photon radiation is evaluated. The corresponding radiation factors are
obtained. The QED renormalization group approach is exploited in the
next-to-leading order. The results are suited to perform a systematic treatment
of the second order next-to-leading logarithmic radiative corrections to
various processes either analytically or numerically.

Characterization of an asynchronous source of heralded single photons
generated at a wavelength of 1550 nm
|
We make a thorough analysis of heralded single photon sources regarding how
factors such as the detector gate-period, the photon rates, the fiber coupling
efficiencies, and the system losses affect the performance of the source. In
the course of this we give a detailed description of how to determine fiber
coupling efficiencies from experimentally measurable quantities. We show that
asynchronous sources perform, under most conditions, better than synchronous
sources with respect to multiphoton events, but only for nearly perfect
coupling efficiencies. We apply the theory to an asynchronous source of
heralded single photons based on spontaneous parametric downconversion in a
periodically poled, bulk, KTiOPO4 crystal. The source generates light with
highly non-degenerate wavelengths of 810 nm and 1550 nm, where the 810 nm
photons are used to announce the presence of the 1550 nm photons inside a
single-mode optical fiber. For our setup we find the probability of having a
1550 nm photon present in the single-mode fiber, as announced by the 810 nm
photon, to be 48%. The probability of multiphoton events is strongly suppressed
compared to a Poissonian light source, giving highly sub-Poisson photon
statistics.

Explicit birational geometry of threefolds of general type
|
Let $V$ be a complex nonsingular projective 3-fold of general type. We prove
$P_{12}(V)>0$ and $P_{24}(V)>1$ (which answers an open problem of J. Kollar and
S. Mori). We also prove that the canonical volume has an universal lower bound
$\text{Vol}(V) \geq 1/2660$ and that the pluri-canonical map $\Phi_m$ is
birational onto its image for all $m\geq 77$. As an application of our method,
we prove Fletcher's conjecture on weighted hyper-surface 3-folds with terminal
quotient singularities. Another featured result is the optimal lower bound
$\text{Vol}(V)\geq {1/420}$ among all those 3-folds $V$ with $\chi({\mathcal
O}_V)\leq 1$.

is discussed. The important role of the quark orbital momentum, which is a
particular case of intrinsic motion, appears as a direct consequence of the
covariant description. Effect of orbital motion is substantial especially for
polarized structure functions. At the same time, the procedure for obtaining
the quark momentum distributions of polarized quarks from the combination of
polarized and unpolarized structure functions is suggested.

Low-energy Dipole Excitations in Nuclei at the N=50,82 and Z=50 Shell
Closures as Signatures for a Neutron Skin
|
Low-energy dipole excitations have been investigated theoretically in N=50,
several N=82 isotones and the Z=50 Sn isotopes. For this purpose a method
incorporating both HFB and multi-phonon QPM theory is applied. A concentration
of one-phonon dipole strength located below the neutron emission threshold has
been calculated in these nuclei. The analysis of the corresponding neutron and
proton dipole transition densities allows to assign a genuine pattern to the
low-energy excitations and making them distinct from the conventional GDR
modes. Analyzing also the QRPA wave functions of the states we can identify
these excitations as Pygmy Dipole Resonance (PDR) modes, recently studied also
in Sn and N=82 nuclei. The results for N=50 are exploratory for an experimental
project designed for the bremsstrahlung facility at the ELBE accelerator.

QCD dynamics at low x in ep collisions at HERA
|
Forward jet and multijet production has been measured at low Bjorken x at
HERA. The measured cross sections and correlations were compared to predictions
from DGLAP-based fixed-order calculations. Further comparisons were made to
DGLAP-based and CCFM-based leading-order Monte Carlo predictions, as well as to
Colour-Dipole model predictions. For the majority of the phase space covered in
the HERA kinematic region, fixed-order calculations describe the data well,
while the leading-order models provide an inconsistent description of the data.

|
In this paper, the axion contribution to the electromagnetic wave propagation
is studied. First we show how the axion electrodynamics model can be embedded
into a premetric formalism of Maxwell electrodynamics. In this formalism, the
axion field is not an arbitrary added Chern-Simon term of the Lagrangian, but
emerges in a natural way as an irreducible part of a general constitutive
tensor.We show that in order to represent the axion contribution to the wave
propagation it is necessary to go beyond the geometric approximation, which is
usually used in the premetric formalism. We derive a covariant dispersion
relation for the axion modified electrodynamics. The wave propagation in this
model is studied for an axion field with timelike, spacelike and null
derivative covectors. The birefringence effect emerges in all these classes as
a signal of Lorentz violation. This effect is however completely different from
the ordinary birefringence appearing in classical optics and in premetric
electrodynamics. The axion field does not simple double the ordinary light cone
structure. In fact, it modifies the global topological structure of light cones
surfaces. In CFJ-electrodynamics, such a modification results in violation of
causality. In addition, the optical metrics in axion electrodynamics are not
pseudo-Riemannian. In fact, for all types of the axion field, they are even
non-Finslerian.

Strong Lensing Analysis of the Cluster RCS0224-0002 at $z=0.77$
|
We present a detailed mass reconstruction of the cluster RCS0224-0002 at
$z=0.773$ from the strong lensing features observed with HST/WFPC2. The mass
profile is reconstructed using a parametric approach. We introduce a novel
method to fit extended multiple images based on the Modified Hausdorff Distance
between observed arcs and the arcs reproduced by the model. We perform the
detailed error analysis of the model parameter using the MCMC method. Our model
reproduces all the observed strong lensing features of the RCS0224-0002 and
predicts the redshift of one of the arcs systems to be $z\approx 2.65$ (the
other system has an spectroscopic redshift of $z=4.87$). The reconstructed
inner mass profile is well fitted by a non-singular isothermal sphere, rather
than with an NFW model. Dark matter substructure, derived from the light
distribution of the most luminous cluster members, is crucial for reproducing
the complexity of the quadrupole image system, which could not be achieved
otherwise. The reconstructed mass distribution closely follows the light,
however it is significantly shifted from the X-ray emission of the gas. The
mass of RCS0224-0002 derived from the lensing model, $\approx 2\times10^{14}
M_\odot$ is in a very good agreement with the one obtained from the X-ray
temperature measured with deep Chandra observations.

Sensitivity of the NEMO detector to galactic microquasars

We present the results of Monte Carlo simulation studies of the capability of
the proposed NEMO km$^3$ telescope to detect TeV muon neutrinos from Galactic
microquasars. In particular we determined the detector sensitivity to each
known microquasar, optimizing the event selection in order to reject the
atmospheric background. We also determined the expected number of source and
background events surviving the selection.

The cluster galaxy luminosity function at $z=0.3$: a recent origin for
the faint-end upturn ?
|
We derive deep luminosity functions (to $M_z=-15$) for galaxies in Abell 1835
($z=0.25$) and AC 114 ($z=0.31$) and compare these with the local $z'$
luminosity function for 69 clusters. The data show that the faint-end upturn,
the excess of galaxies above a single Schechter function at $M_z < -17$, does
not exist in the higher redshift clusters. This suggests that the faint-end
upturn galaxies have been created recently, by infall into clusters of
star-forming field populations or via tidal disruption of brighter objects.^M

Injectivity and Projectivity in Analysis and Topology
|
We give new proofs for many injectivity results in analysis that make more
careful use of the duality between unital abelian C*-algebras and compact
Hausdorff spaces. We then extend many of these results to incorporate group
actions. Our approach uses only elementary topological constructions and
eliminates the need for results from the theory of Boolean algebras and
AW*-algebras that were used in earlier proofs.

The forgotten monoid
|
We study properties of the forgotten monoid which appeared in work of Lascoux
and Schutzenberger and recently resurfaced in the construction of dual
equivalence graphs by Assaf. In particular, we provide an explicit
characterization of the forgotten classes in terms of inversion numbers and
show that there are n^2-3n+4 forgotten classes in the symmetric group S_n. Each
forgotten class contains a canonical element that can be characterized by
pattern avoidance. We also show that the sum of Gessel's quasi-symmetric
functions over a forgotten class is a 0-1 sum of ribbon-Schur functions.

Constraining the Two-Higgs-Doublet-Model parameter space
|
We confront the Two-Higgs-Doublet Model with a variety of experimental
constraints as well as theoretical consistency conditions. The most
constraining data are the \bar B\to X_s\gamma decay rate (at low values of
M_{H^\pm}), and \Delta\rho (at both low and high M_{H^\pm}). We also take into
account the B\bar B oscillation rate and R_b, or the width \Gamma(Z\to b\bar b)
(both of which restrict the model at low values of \tan\beta), and the
B^-\to\tau\nu_\tau decay rate, which restricts the model at high \tan\beta and
low M_{H^\pm}. Furthermore, the LEP2 non-discovery of a light, neutral Higgs
boson is considered, as well as the muon anomalous magnetic moment. Since
perturbative unitarity excludes high values of \tan\beta, the model turns out
to be very constrained. We outline the remaining allowed regions in the
\tan\beta-M_{H^\pm} plane for different values of the masses of the two
lightest neutral Higgs bosons, and describe some of their properties.

Searches in Photon and Jet States
|
We present recent results from the Collider Detector at Fermilab (CDF) and D0
experiments using data from proton-antiproton collisions with sqrt(s) = 1.96
TeV at Run II of the Fermilab Tevatron. New physics may appear in events with
high transverse momentum objects, including photons and quark or gluon jets.
The results described here are of signature-based searches and model-based
searches probing supersymmetry, leptoquarks, 4th generation quarks, and large
extra dimensions.

Discovery of diffuse radio emission at the center of the most
X-ray-luminous cluster RX J1347.5-1145
|
We report on new VLA radio observations of the distant cluster RX
J1347.5-1145, which is the most luminous in X-rays. We aim at investigating the
possible presence of diffuse and extended radio emission in this very peculiar
system which shows both a massive cooling flow and merging signatures. New low
resolution (~18 arcsec) VLA radio observations of this cluster are combined
with higher resolution (~2 arcsec) data available in the VLA archive. We
discover the presence of a diffuse and extended (~500 kpc) radio source
centered on the cluster, unrelated to the radio emission of the central AGN.
The properties of the radio source, in particular a) its occurrence at the
center of a massive cooling flow cluster, b) its total size comparable to that
of the cooling region, c) its agreement with the observational trend between
radio luminosity and cooling flow power, indicate that RX J1347.5-1145 hosts a
radio mini-halo. We suggest that the radio emission of this mini-halo, which is
the most distant object of its class discovered up to now, is due to electron
re-acceleration triggered by the central cooling flow. However, we also note
that the morphology of the diffuse radio emission shows an elongation
coincident with the position of a hot subclump detected in X-rays, thus
suggesting that additional energy for the electron re-acceleration might be
provided by the submerger event.

Mass distribution in the most X-ray-luminous galaxy cluster RX
J1347.5-1145 studied with XMM-Newton
|
We report on the analysis of XMM-Newton observations of RX J1347.5-1145
(z=0.451), the most X-ray-luminous galaxy cluster. We present a detailed total
and gas mass determination up to large distances (~1.7 Mpc), study the scaling
properties of the cluster, and explore the role of AGN heating in the cluster
cool core. By means of spatially resolved spectroscopy we derive density,
temperature, entropy, and cooling time profiles of the intra-cluster medium. We
compute the total mass profile of the cluster in the assumption of hydrostatic
equilibrium. If the disturbed south-east region of the cluster is excluded from
the analysis, our results on shape, normalization, scaling properties of
density, temperature, entropy, and cooling time profiles are fully consistent
with those of relaxed, cool core clusters. We compare our total and gas mass
estimates with previous X-ray, lensing, dynamical, and SZ studies. We find good
agreement with other X-ray results, dynamical mass measurements, weak lensing
masses and SZ results. We confirm a discrepancy of a factor ~2 between strong
lensing and X-ray mass determinations and find a gross mismatch between our
total mass estimate and the mass reconstructed through the combination of both
strong and weak lensing. We explore the effervescent heating scenario in the
core of RX J1347.5-1145 and find support to the picture that AGN outflows and
heat conduction are able to quenching radiative cooling.

Potential energy curves and transition moments for the excimer states
0u+ (3P1) and 1u (3P2) of Ar2
|
Exactly solvable rererence potentials of several smoothly joined Morse-type
components were constructed for the lowest two excimer states of Ar2 molecule.
The parameters of the potentials have been ascertained by fitting to the
experimental data, and they are reliable in a wide range of nuclear
separations. A large number of quantum mechanical Franck-Condon factors for
bound-free and bound-bound transitions have been calculated and compared with
the observed spectroscopic features. The fitting procedure also involved dipole
transition moments, which have been adjusted to the known radiative lifetimes
of the vibrational levels. The resulting potential energy curves accurately
reproduce the first and the second emission continua of Ar2* as well as the
oscillatory spectrum related to their inner turning point region. The numbering
and the positions of the vibrational levels reported by Herman et al. [P. R.
Herman, P. E. LaRocque, and B. P. Stoicheff, J. Chem. Phys. 89, 4535 (1988)]
have been confirmed.

Connections between real polynomial solutions of hypergeometric-type
differential equations with Rodrigues formula
|
Starting from the Rodrigues representation of polynomial solutions of the
general hypergeometric-type differential equation complementary polynomials are
constructed using a natural method. Among the key results is a generating
function in closed form leading to short and transparent derivations of
recursion relations and an addition theorem. The complementary polynomials
satisfy a hypergeometric-type differential equation themselves, have a
three-term recursion among others and obey Rodrigues formulas. Applications to
the classical polynomials are given.

Strong extinction of a far-field laser beam by a single quantum dot
|
Through the utilization of index-matched GaAs immersion lens techniques we
demonstrate a record extinction (12%) of a far-field focused laser by a single
InAs/GaAs quantum dot. This contrast level enables us to report for the first
time resonant laser transmission spectroscopy on a single InAs/GaAs quantum dot
without the need for phase-sensitive lock-in detection.

Two Stellar Components in the Halo of the Milky Way
|
The halo of the Milky Way provides unique elemental abundance and kinematic
information on the first objects to form in the Universe, which can be used to
tightly constrain models of galaxy formation and evolution. Although the halo
was once considered a single component, evidence for its dichotomy has slowly
emerged in recent years from inspection of small samples of halo objects. Here
we show that the halo is indeed clearly divisible into two broadly overlapping
structural components -- an inner and an outer halo -- that exhibit different
spatial density profiles, stellar orbits and stellar metallicities (abundances
of elements heavier than helium). The inner halo has a modest net prograde
rotation, whereas the outer halo exhibits a net retrograde rotation and a peak
metallicity one-third that of the inner halo. These properties indicate that
the individual halo components probably formed in fundamentally different ways,
through successive dissipational (inner) and dissipationless (outer) mergers
and tidal disruption of proto-Galactic clumps.

Recollement of Deformed Preprojective Algebras and the Calogero-Moser
Correspondence
|
The aim of this paper is to clarify the relation between the following
objects: $ (a) $ rank 1 projective modules (ideals) over the first Weyl algebra
$ A_1(\C)$; $ (b) $ simple modules over deformed preprojective algebras $
\Pi_{\lambda}(Q) $ introduced by Crawley-Boevey and Holland; and $ (c) $ simple
modules over the rational Cherednik algebras $ H_{0,c}(S_n) $ associated to
symmetric groups. The isomorphism classes of each type of these objects can be
parametrized geometrically by the same space (namely, the Calogero-Moser
algebraic varieties); however, no natural functors between the corresponding
module categories seem to be known. We construct such functors by translating
our earlier results on $\A$-modules over $ A_1 $ to a more familiar setting of
representation theory. In the last section we extend our construction to the
case of Kleinian singularities $ \C^2/\Gamma $, where $ \Gamma $ is a finite
cyclic subgroup of $ \SL(2, \C) $.

the aim of this paper is to clarify the relation between the following objects a rank 1 projective modules ideals over the first weyl algebra a_1c b simple modules over deformed preprojective algebras pi_lambdaq introduced by crawleyboevey and holland and c simple modules over the rational cherednik algebras h_0cs_n associated to symmetric groups the isomorphism classes of each type of these objects can be parametrized geometrically by the same space namely the calogeromoser algebraic varieties however no natural functors between the corresponding module categories seem to be known we construct such functors by translating our earlier results on amodules over a_1 to a more familiar setting of representation theory in the last section we extend our construction to the case of kleinian singularities c2gamma where gamma is a finite cyclic subgroup of sl2 c

Relations among Supersymmetric Lattice Gauge Theories via Orbifolding
|
We show how to derive Catterall's supersymmetric lattice gauge theories
directly from the general principle of orbifolding followed by a variant of the
usual deconstruction. These theories are forced to be complexified due to a
clash between charge assignments under U(1)-symmetries and lattice assignments
in terms of scalar, vector and tensor components for the fermions. Other
prescriptions for how to discretize the theory follow automatically by
orbifolding and deconstruction. We find that Catterall's complexified model for
the two-dimensional N=(2,2) theory has two independent preserved
supersymmetries. We comment on consistent truncations to lattice theories
without this complexification and with the correct continuum limit. The
construction of lattice theories this way is general, and can be used to derive
new supersymmetric lattice theories through the orbifolding procedure. As an
example, we apply the prescription to topologically twisted four-dimensional
N=2 supersymmetric Yang-Mills theory. We show that a consistent truncation is
closely related to the lattice formulation previously given by Sugino.

A Generic Deployment Framework for Grid Computing and Distributed
Applications
|
Deployment of distributed applications on large systems, and especially on
grid infrastructures, becomes a more and more complex task. Grid users spend a
lot of time to prepare, install and configure middleware and application
binaries on nodes, and eventually start their applications. The problem is that
the deployment process is composed of many heterogeneous tasks that have to be
orchestrated in a specific correct order. As a consequence, the automatization
of the deployment process is currently very difficult to reach. To address this
problem, we propose in this paper a generic deployment framework allowing to
automatize the execution of heterogeneous tasks composing the whole deployment
process. Our approach is based on a reification as software components of all
required deployment mechanisms or existing tools. Grid users only have to
describe the configuration to deploy in a simple natural language instead of
programming or scripting how the deployment process is executed. As a toy
example, this framework is used to deploy CORBA component-based applications
and OpenCCM middleware on one thousand nodes of the French Grid5000
infrastructure.

Application of a design space exploration tool to enhance interleaver
generation
|
This paper presents a methodology to efficiently explore the design space of
communication adapters. In most digital signal processing (DSP) applications,
the overall performance of the system is significantly affected by
communication architectures, as a consequence the designers need specifically
optimized adapters. By explicitly modeling these communications within an
effective graph-theoretic model and analysis framework, we automatically
generate an optimized architecture, named Space-Time AdapteR (STAR). Our design
flow inputs a C description of Input/Output data scheduling, and user
requirements (throughput, latency, parallelism...), and formalizes
communication constraints through a Resource Constraints Graph (RCG). Design
space exploration is then performed through associated tools, to synthesize a
STAR component under time-to-market constraints. The proposed approach has been
tested to design an industrial data mixing block example: an Ultra-Wideband
interleaver.

Quasi-invariance properties of a class of subordinators
|
We study absolute-continuity properties of a class of stochastic processes,
including the gamma and the Dirichlet processes. We prove that the laws of a
general class of non-linear transformations of such processes are locally
equivalent to the law of the original process and we compute explicitly the
associated Radon-Nikodym densities. This work unifies and generalizes to random
non-linear transformations several previous results on quasi-invariance of
gamma and Dirichlet processes.

pseudoscalar form factor, $G_p(q^2)$, as well as the pion-nucleon form factor,
$G_{\pi N N}(q^2)$, in lattice QCD. We also evaluate the corresponding nucleon
to $\Delta$ transition form factors, $C_5^A(q^2)$ and $C_6^A(q^2)$, and the
pion-nucleon-$\Delta$ form factor $G_{\pi N\Delta}(q^2)$. The nucleon form
factors are evaluated in the quenched theory and with two degenerate flavors of
dynamical Wilson fermions. The nucleon to $\Delta$ form factors, besides Wilson
fermions, are evaluated using domain wall valence fermions with staggered sea
quark configurations for pion masses as low as about 350 MeV. Using these form
factors, together with an evaluation of the renormalized quark mass, we
investigate the validity of the diagonal and non-diagonal Goldberger-Treiman
relations. The ratios $G_{\pi N\Delta}(q^2)/G_{\pi NN}(q^2)$ and
$2C_5^A(q^2)/G_A(q^2)$ are constant as a function of the momentum transfer
squared and show almost no dependence on the quark mass. We confirm equality of
these two ratios consistent with the Goldberger-Treiman relations extracting a
mean value of $1.61(2)$.

Unbound exotic nuclei studied by projectile fragmentation
|
We call "projectile fragmentation" of neutron halo nuclei the elastic breakup
(diffraction) reaction, when the observable studied is the neutron-core
relative energy spectrum. This observable has been measured in relation to the
Coulomb breakup on heavy target and recently also on light targets. Such data
enlighten the effect of the neutron final state interaction with the core of
origin. Projectile fragmentation is studied here by a time dependent model for
the excitation of a nucleon from a bound state to a continuum resonant state in
a neutron-core complex potential which acts as a final state interaction.
The final state is described by an optical model S-matrix so that both
resonant and non resonant states of any continuum energy can be studied as well
as deeply bound initial states. It turns out that due to the coupling between
the initial and final states, the neutron-core free particle phase shifts are
modified, in the exit channel, by an additional phase.
Some typical numerical calculations for the relevant observables are
presented and compared to experimental data. It is suggest that the excitation
energy spectra of an unbound nucleus might reflect the structure of the parent
nucleus from whose fragmentation they are obtained.

Oscillation regimes of a solid-state ring laser with active beat note
stabilization : from a chaotic device to a ring laser gyroscope
|
We report experimental and theoretical study of a rotating diode-pumped
Nd-YAG ring laser with active beat note stabilization. Our experimental setup
is described in the usual Maxwell-Bloch formalism. We analytically derive a
stability condition and some frequency response characteristics for the
solid-state ring laser gyroscope, illustrating the important role of mode
coupling effects on the dynamics of such a device. Experimental data are
presented and compared with the theory on the basis of realistic laser
parameters, showing a very good agreement. Our results illustrate the duality
between the very rich non linear dynamics of the diode-pumped solid-state ring
laser (including chaotic behavior) and the possibility to obtain a very stable
beat note, resulting in a potentially new kind of rotation sensor.
