710.2753 | Effects of anharmonic vibration on large-angle quasi-elastic scattering
of 16O+144Sm | We study the effects of double octupole and quadrupole phonon excitations in
the 144Sm nucleus on quasi-elastic 16O+144Sm scattering at backward angles. To
this end, we use the coupled-channels framework, taking into account explicitly
the anharmonicities of the vibrations. We use the same coupling scheme as that
previously employed to explain the experimental data of sub-barrier fusion
cross sections for the same system. We show that the experimental data for the
quasi-elastic cross sections are well reproduced in this way, although the
quasi-elastic barrier distribution has a distinct high energy peak which is
somewhat smeared in the experimental barrier distribution. We also discuss the
effects of proton transfer on the quasi-elastic barrier distribution. Our study
indicates that the fusion and quasi-elastic barrier distributions for this
system cannot be accounted for simultaneously with the standard
coupled-channels approach.

710.2754 | A comparison between detailed and configuration-averaged
collisional-radiative codes applied to non-local thermal equilibrium plasma | A collisional-radiative model describing nonlocal-thermodynamic-equilibrium
plasmas is developed. It is based on the HULLAC (Hebrew University Lawrence
Livermore Atomic Code) suite for the transitions rates, in the zero-temperature
radiation field hypothesis. Two variants of the model are presented: the first
one is configuration averaged, while the second one is a detailed level
version. Comparisons are made between them in the case of a carbon plasma; they
show that the configuration-averaged code gives correct results for an
electronic temperature Te=10 eV (or higher) but fails at lower temperatures
such as Te=1 eV. The validity of the configuration-averaged approximation is
discussed: the intuitive criterion requiring that the average
configuration-energy dispersion must be less than the electron thermal energy
turns out to be a necessary but far from sufficient condition. Another
condition based on the resolution of a modified rate-equation system is
proposed. Its efficiency is emphasized in the case of low-temperature plasmas.
Finally, it is shown that near-threshold autoionization cascade processes may
induce a severe failure of the configuration-average formalism.

710.2755 | Reduced branching processes with very heavy tails | The reduced Markov branching process is a stochastic model for the genealogy
of an unstructured biological population. Its limit behavior in the critical
case is well studied for the Zolotarev-Slack regularity parameter
$\alpha\in(0,1]$. We turn to the case of very heavy tailed reproduction
distribution $\alpha=0$ assuming Zubkov's regularity condition with parameter
$\beta\in(0,\infty)$. Our main result gives a new asymptotic pattern for the

710.2756 | From Holonomy of the Ising Model Form Factors to n-Fold Integrals and
the Theory of Elliptic Curve | We recall the form factors $ f^{(j)}_{N,N}$ corresponding to the
$\lambda$-extension $C(N,N; \lambda)$ of the two-point diagonal correlation
function of the Ising model on the square lattice and their associated linear
differential equations which exhibit both a ``Russian-doll'' nesting, and a
decomposition of the linear differential operators as a direct sum of operators
(equivalent to symmetric powers of the differential operator of the complete
elliptic integral $E$). The scaling limit of these differential operators
breaks the direct sum structure but not the ``Russian doll'' structure, the
``scaled'' linear differential operators being no longer Fuchsian. We then
introduce some multiple integrals of the Ising class expected to have the same
singularities as the singularities of the $n$-particle contributions
$\chi^{(n)}$ to the susceptibility of the square lattice Ising model. We find
the Fuchsian linear differential equations satisfied by these multiple
integrals for $n=1,2,3,4$ and, only modulo a prime, for $n=5$ and 6, thus
providing a large set of (possible) new singularities of the $\chi^{(n)}$. ...

710.2757 | Future plan for observation of cosmic gamma rays in the 100 TeV energy
region with the Tibet air shower array : physics goal and overview | The Tibet air shower array, which has an effective area of 37,000 square
meters and is located at 4300 m in altitude, has been observing air showers
induced by cosmic rays with energies above a few TeV. We are planning to add a
large muon detector array to it for the purpose of increasing its sensitivity
to cosmic gamma rays in the 100 TeV (10 - 1000 TeV) energy region by
discriminating them from cosmic-ray hadrons. We report on the possibility of
detection of gamma rays in the 100 TeV energy region in our field of view,

710.2758 | The fundamental theorem of asset pricing under proportional transaction
costs | We extend the fundamental theorem of asset pricing to a model where the risky
stock is subject to proportional transaction costs in the form of bid-ask
spreads and the bank account has different interest rates for borrowing and
lending. We show that such a model is free of arbitrage if and only if one can
embed in it a friction-free model that is itself free of arbitrage, in the
sense that there exists an artificial friction-free price for the stock between
its bid and ask prices and an artificial interest rate between the borrowing
and lending interest rates such that, if one discounts this stock price by this
interest rate, then the resulting process is a martingale under some
non-degenerate probability measure. Restricting ourselves to the simple case of
a finite number of time steps and a finite number of possible outcomes for the
stock price, the proof follows by combining classical arguments based on
finite-dimensional separation theorems with duality results from linear
optimisation.

710.2759 | Structural anomalies, spin transitions and charge disproportionation in
LnCoO3 | The diamagnetic-paramagnetic and insulator-metal transitions in LnCoO3
perovskites (Ln = La, Y, rare earths) are reinterpreted and modeled as a
two-level excitation process. In distinction to previous models, the present
approach can be characterized as a LS-HS-IS (low-high-intermediate spin)
scenario. The first level is the local excitation of HS Co3+ species in the LS
ground state. The second excitation is based on the interatomic electron
transfer between the LS/HS pairs, leading finally to a stabilization of the
metallic phase based on IS Co3+. The model parameters have been quantified for
Ln = La, Pr and Nd samples using the powder neutron diffraction on the thermal
expansion of Co-O bonds, that is associated with the two successive spin

710.2761 | VLT-VIMOS integral field spectroscopy of luminous and ultraluminous
infrared galaxies. I. The sample and first results | (Ultra)Luminous Infrared Galaxies [(U)LIRGs] are much more numerous at
cosmological distances than locally, and are likely precursors of elliptical
galaxies. Our goal is to carry out an integral field spectroscopic survey of a
representative sample of low redshift (z < 0.26) (U)LIRGs, covering different
morphologies from spirals to mergers over the entire infrared luminosity range.
The present study is based on optical IFS obtained with the VIMOS instrument on
the VLT. The first results of this survey are presented here with the study of
two galaxies representative of the two major morphological types observed in
(U)LIRGs, interacting pairs and morphologically- regular, weakly-interacting
spirals, respectively. We have found that IRAS 06076-2139 consists of two
low-intermediate mass (0.15 and 0.4 m*) galaxies with relative velocities of ~
550 km/s and, therefore, it is unlikely that they will merge. The VIMOS IFS has
also discovered the presence of a rapidly expanding and rotating ring of gas in
the southern galaxy (Gs), likely due to a nearly central head-on passage of an
intruder about 140 million years ago. IRASF 12115-4656 is a spiral for which we
have found a mass of 1.2 m*. The neutral gas (traced by the NaI doublet) and
ionized gas components are spatially and kinematically decoupled. The analysis
presented here illustrates the full potential of IFS in two important aspects:
(i) the study of the kinematics and ionization structure of complex
interacting/merging systems, and (2i) the study of the kinematics of the
different gas phases, neutral (cool) and ionized (warm), traced by the NaD and
Halpha lines, respectively. (abbreviated)

710.2764 | On the Equivalent Theory of the Generalized \tau^{(2)}-model and the
Chiral Potts Model with two Alternating Vertical Rapidities | By the Baxter's $Q_{72}$-operator method, we demonstrate the equivalent
theory between the generalized $\tau^{(2)}$-model (other than two special cases
with a pseudovacuum state) and the $N$-state chiral Potts model with two
alternating vertical rapidities, where the degenerate models are included. As a
consequence, the theory of the XXZ chain model associated to cyclic
representations (with the parameter $\varsigma$) of $U_{\sf q}(sl_2)$ with
${\sf q}^N=1$ for odd $N$ is identified with either (for $\varsigma^N=1$) the
chiral Potts model with two superintegrable vertical rapidities, or (for
$\varsigma^N \neq 1$) the degenerate model for the selfdual solution of the
star-triangle relation. In all these identifications, the transfer matrices $T,
\hat{T}$ of the chiral Potts model (including the degenerate ones) serve as the

prequantization''. An extension is presented here which covers quantum systems
that are characterized by a complete set of mutually commuting Hermitian
operators (``beables''). We introduce the symmetry of beables: any complete set
of beables is as good as any other one which is obtained through a real general
linear group transformation. The quantum numbers of a specific set are related
to symmetry breaking initial and boundary conditions in a deterministic model.
The Hamiltonian, in particular, can be taken as the emergent beable which

710.2766 | Thermodynamic properties of Holstein polarons and the effects of
disorder | The ground state and finite temperature properties of polarons are studied
considering a two-site and a four-site Holstein model by exact diagonalization
of the Hamiltonian. The kinetic energy, Drude weight, correlation functions
involving charge and lattice deformations, and the specific heat have been
evaluated as a function of electron-phonon (e-ph) coupling strength and
temperature. The effects of site diagonal disorder on the above properties have
been investigated. The disorder is found to suppress the kinetic energy and the
Drude weight, reduces the spatial extension of the polaron, and makes the
large-to-small polaron crossover smoother. Increasing temperature also plays
similar role. For strong coupling the kinetic energy arises mainly from the
incoherent hopping processes owing to the motion of electrons within the
polaron and is almost independent of the disorder strength. From the coherent
and incoherent contributions to the kinetic energy, the temperature above which

710.2769 | Renormalization of the vacuum angle in quantum mechanics, Berry phase
and continuous measurements | The vacuum angle $\theta$ renormalization is studied for a toy model of a
quantum particle moving around a ring, threaded by a magnetic flux $\theta$.
Different renormalization group (RG) procedures lead to the same generic RG
flow diagram, similar to that of the quantum Hall effect. We argue that the
renormalized value of the vacuum angle may be observed if the particle's
position is measured with finite accuracy or coupled to additional slow
variable, which can be viewed as a coordinate of a second (heavy) particle on
the ring. In this case the renormalized $\theta$ appears as a magnetic flux

710.2772 | Significant g-factor values of a two-electron ground state in quantum
dots with spin-orbit coupling | The magnetization of semiconductor quantum dots in the presence of spin-orbit
coupling and interactions is investigated numerically. When the dot is occupied
by two electrons we find that a level crossing between the two lowest many-body
eigenstates may occur as a function of the spin-orbit coupling strength. This
level crossing is accompanied by a non-vanishing magnetization of the
ground-state. Using first order perturbation theory as well as exact numerical
diagonalization of small clusters we show that the tendency of interactions to
cause Stoner-like instability is enhanced by the SO coupling. The resulting
g-factor can have a significant value, and thus may influence g-factor

a Dirac quantization rule for Ramond-Ramond fluxes, and study flat

710.2775 | Dam Rain and Cumulative Gain | We consider a financial contract that delivers a single cash flow given by
the terminal value of a cumulative gains process. The problem of modelling and
pricing such an asset and associated derivatives is important, for example, in
the determination of optimal insurance claims reserve policies, and in the
pricing of reinsurance contracts. In the insurance setting, the aggregate
claims play the role of the cumulative gains, and the terminal cash flow
represents the totality of the claims payable for the given accounting period.
A similar example arises when we consider the accumulation of losses in a
credit portfolio, and value a contract that pays an amount equal to the
totality of the losses over a given time interval. An explicit expression for
the value process is obtained. The price of an Arrow-Debreu security on the
cumulative gains process is determined, and is used to obtain a closed-form
expression for the price of a European-style option on the value of the asset.
The results obtained make use of various remarkable properties of the gamma
bridge process, and are applicable to a wide variety of financial products
based on cumulative gains processes such as aggregate claims, credit portfolio
losses, defined-benefit pension schemes, emissions, and rainfall.
| q-fin.PR math.PR | we consider a financial contract that delivers a single cash flow given by the terminal value of a cumulative gains process the problem of modelling and pricing such an asset and associated derivatives is important for example in the determination of optimal insurance claims reserve policies and in the pricing of reinsurance contracts in the insurance setting the aggregate claims play the role of the cumulative gains and the terminal cash flow represents the totality of the claims payable for the given accounting period a similar example arises when we consider the accumulation of losses in a credit portfolio and value a contract that pays an amount equal to the totality of the losses over a given time interval an explicit expression for the value process is obtained the price of an arrowdebreu security on the cumulative gains process is determined and is used to obtain a closedform expression for the price of a europeanstyle option on the value of the asset the results obtained make use of various remarkable properties of the gamma bridge process and are applicable to a wide variety of financial products based on cumulative gains processes such as aggregate claims credit portfolio losses definedbenefit pension schemes emissions and rainfall | [['we', 'consider', 'a', 'financial', 'contract', 'that', 'delivers', 'a', 'single', 'cash', 'flow',

710.2776 | New constraints on the membership of the T dwarf S Ori 70 in the sigma
Orionis cluster | (Abridged) The nature of S Ori 70, a faint mid-T type object found towards
the direction of the young sigma Orionis cluster, is still under debate. We
intend to disentangle whether it is a field brown dwarf or a 3-Myr old
planetary-mass member of the cluster. We report on near-infrared JHK_s and
mid-infrared [3.6] and [4.5] IRAC/Spitzer photometry recently obtained for S
Ori 70. The new near-infrared images (taken 3.82 yr after the discovery data)
have allowed us to derive a very small proper motion (11.0 +/- 5.9 mas/yr) for
this object, which is consistent with the proper motion of the cluster within
1.5 sigma the astrometric uncertainty. The colors (H-K_s), (J-K_s) and
K_s-[3.6] appear discrepant when compared to T4-T7 dwarfs in the field. This
behavior could be ascribed to a low-gravity atmosphere or alternatively to an
atmosphere with a metallicity significantly different than solar. Taking into
account the small proper motion of S Ori 70 and its new near- and mid-infrared
colors, a low-gravity atmosphere remains as the most likely explanation to
account for our observations. This supports S Ori 70's membership in sigma
Orionis, with an estimated mass in the interval 2-7 Mjup, in agreement with our
previous derivation.

710.2777 | Teleportation of two-mode squeezed states | We consider two-mode squeezed states which are parametrized by the squeezing
parameter and the phase. We present a scheme for teleporting such entangled
states of continuous variables from Alice to Bob. Our protocol is
operationalized through the creation of a four-mode entangled state shared by
Alice and Bob using linear amplifiers and beam splitters. Teleportation of the
entangled state proceeds with local operations and the classical communication
of four bits. We compute the fidelity of teleportation and find that it

two different atomic species. The quantum degenerate mixture is realized
employing sympathetic cooling of fermionic Li-6 and K-40 gases by an
evaporatively cooled bosonic Rb-87 gas. We describe the combination of trapping
and cooling methods that proved crucial to successfully cool the mixture. In
particular, we study the last part of the cooling process and show that the
efficiency of sympathetic cooling of the Li-6 gas by Rb-87 is increased by the
presence of K-40 through catalytic cooling. Due to the differing physical
properties of the two components, the quantum degenerate Li-6 K-40 Fermi-Fermi
mixture is an excellent candidate for a stable, heteronuclear system allowing
to study several so far unexplored types of quantum matter.

and Small Magellanic Clouds (SMC) are presented. The PL diagrams are plotted in
three planes: logP-K_S, logP-W_{JK}, and logP-W_I. Fourteen PL sequences are
distinguishable, and some of them consist of three closely spaced ridges. Each
of the sequences is fitted with a linear or quadratic function. The
similarities and differences between the PL relations in both galaxies are
discussed for four types of red giant variability: OGLE Small Amplitude Red
Giants (OSARGs), Miras and Semiregular Variables (SRVs), Long Secondary Periods
(LSPs) and ellipsoidal variables. We propose a new method of separating OSARGs
from non-variable stars and SRVs. The method employs the position in the
reddening-free PL diagrams and the characteristic period ratios of these
multiperiodic variables. The PL relations for the LMC OSARG are compared with
the calculated relations for RGB models along isochrones of relevant ages and
metallicities. We also compare measured periods and amplitudes of the OSARGs
with predictions based on the relations valid for less luminous solar-like
pulsators. Miras and SRVs seem to follow PL relation of the same slopes in the
LMC and SMC, while for LSP and ellipsoidal variables slopes in both galaxies
are different. The PL sequences defined by LSP variables and binary systems
overlap in the whole range of analyzed wavebands. We put forward new arguments
for the binary star scenario as an explanation of the LSP variability and
elaborate on it further. The measured pulsation to orbital period ratio implies
nearly constant ratio of the star radius to orbital distance, R/A=0.4, as we
find. Combined effect of tidal friction and mass loss enhanced by the low-mass
companion may explain why such a value is preferred.

710.2781 | Rhombus Filtrations and Rauzy Algebras | Peach introduced rhombal algebras associated to quivers given by tilings of
the plane by rhombi. We develop general techniques to analyse rhombal algebras,
including a filtration by what we call rhombus modules.
We introduce a way to relate the infinite-dimensional rhombal algebra
corresponding to a complete tiling of the plane to finite-dimensional algebras
corresponding to finite portions of the tiling. Throughout, we apply our
general techniques to the special case of the Rauzy tiling, which is built in
stages reflecting an underlying self-similarity. Exploiting this self-similar
structure allows us to uncover interesting features of the associated
finite-dimensional algebras, including some of the tree classes in the stable
Auslander-Reiten quiver.

710.2782 | Effective linkage learning using low-order statistics and clustering | The adoption of probabilistic models for the best individuals found so far is
a powerful approach for evolutionary computation. Increasingly more complex
models have been used by estimation of distribution algorithms (EDAs), which
often result better effectiveness on finding the global optima for hard
optimization problems. Supervised and unsupervised learning of Bayesian
networks are very effective options, since those models are able to capture
interactions of high order among the variables of a problem. Diversity
preservation, through niching techniques, has also shown to be very important
to allow the identification of the problem structure as much as for keeping
several global optima. Recently, clustering was evaluated as an effective
niching technique for EDAs, but the performance of simpler low-order EDAs was
not shown to be much improved by clustering, except for some simple multimodal
problems. This work proposes and evaluates a combination operator guided by a

710.2783 | Void Statistics and Void Galaxies in the 2dFGRS | For the 2dFGRS we study the properties of voids and of fainter galaxies
within voids that are defined by brighter galaxies. Our results are compared
with simulated galaxy catalogues from the Millenium simulation coupled with a
semianalytical galaxy formation recipe. We derive the void size distribution
and discuss its dependence on the faint magnitude limit of the galaxies
defining the voids. While voids among faint galaxies are typically smaller than
those among bright galaxies, the ratio of the void sizes to the mean galaxy
separation reaches larger values. This is well reproduced in the mock galaxy
samples studied. We provide analytic fitting functions for the void size
distribution. Furthermore, we study the galaxy population inside voids defined
by objects with $B_J -5\log{h}< -20$ and diameter larger than 10 \hMpc. We find
a clear bimodality of the void galaxies similar to the average comparison
sample. We confirm the enhanced abundance of galaxies in the blue cloud and a
depression of the number of red sequence galaxies. There is an indication of a
slight blue shift of the blue cloud. Furthermore, we find that galaxies in void
centers have higher specific star formation rates as measured by the $\eta$
parameter. We determine the radial distribution of the ratio of early and late
type galaxies through the voids. We find and discuss some differences between
observations and the Millenium catalogues.

710.2784 | Routes to thermodynamic limit on scale-free networks | We show that there are two classes of finite size effects for dynamic models
taking place on a scale-free topology. Some models in finite networks show a
behavior that depends only on the system size N. Others present an additional
distinct dependence on the upper cutoff k_c of the degree distribution. Since
the infinite network limit can be obtained by allowing k_c to diverge with the
system size in an arbitrary way, this result implies that there are different
routes to the thermodynamic limit in scale-free networks. The contact process
(in its mean-field version) belongs to this second class and thus our results

710.2787 | The shuffle Hopf algebra and quasiplanar Wick products | The operator valued distributions which arise in quantum field theory on the
noncommutative Minkowski space can be symbolized by a generalization of chord
diagrams, the dotted chord diagrams. In this framework, the combinatorial
aspects of quasiplanar Wick products are understood in terms of the shuffle
Hopf algebra of dotted chord diagrams, leading to an algebraic characterization

710.2789 | SGR 1806-20 about two years after the giant flare: Suzaku, XMM-Newton
and INTEGRAL observations | In December 2004, the soft gamma-ray repeater SGR 1806-20 emitted the most
powerful giant flare ever observed. This probably involved a large-scale
rearrangement of the magnetosphere leading to observable variations in the
properties of its X-ray emission. Here we present the results of the first
Suzaku observation of SGR 1806-20, together with almost simultaneous
observations with XMM-Newton and INTEGRAL. The source seems to have reached a
state characterized by a flux close to the pre-flare level and by a relatively
soft spectrum. Despite this, SGR 1806-20 remained quite active also after the
giant flare, allowing us to study several short bursts observed by Suzaku in
the 1-100 keV range. We discuss the broad-band spectral properties of SGR
1806-20, covering both persistent and bursting emission, in the context of the
magnetar model, and consider its recent theoretical developments.

710.279 | PNJL model with a Van der Monde term | We extend the Polyakov-Nambu-Jona-Lasinio (PNJL) model for two degenerate
flavours by including the effect of the SU(3) measure with a Van der Monde
(VdM) term. This ensures that the Polyakov loop always remains in the domain
[0,1]. The pressure, energy density, specific heat, speed of sound and
conformal measure show small or negligible effects from this term. However
various quark number and isospin susceptibilities are all found to approach
their respective ideal gas limits around 2 $T_c$. We compare our methods with

710.2792 | Market completion using options | Mathematical models for financial asset prices which include, for example,
stochastic volatility or jumps are incomplete in that derivative securities are
generally not replicable by trading in the underlying. In earlier work (2004)
the first author provided a geometric condition under which trading in the
underlying and a finite number of vanilla options completes the market. We
complement this result in several ways. First, we show that the geometric
condition is not necessary and a weaker, necessary and sufficient, condition is
presented. While this condition is generally not directly verifiable, we show
that it simplifies to matrix non-degeneracy in a single point when the pricing
functions are real analytic functions. In particular, any stochastic volatility
model is then completed with an arbitrary European type option. Further, we
show that adding path-dependent options such as a variance swap to the set of
primary assets, instead of plain vanilla options, also completes the market.

hard-X-ray tail persisting for 380 s with a modulation period of 7.56 s. This
event has received considerable attention, particularly in the astrophysics
area. Its relevance to the geophysics community lies in the importance of
investigating the effects of such an event on the near-earth electromagnetic
environment. However, the signature of a magnetar flare on the geomagnetic
field has not previously been investigated. Here, by applying wavelet analysis
to the high-resolution magnetic data provided by the CHAMP satellite, a
modulated signal with a period of 7.5 s over the duration of the giant flare
appears in the observed data. Moreover, this event was detected by the
energetic ion counters onboard the DEMETER satellite.

710.2796 | On the Limitations of the Color Dipole Picture | We discuss two aspects of the color dipole picture of high energy
photon-proton scattering. First we present bounds on various ratios of deep
inelastic structure functions resulting from the dipole picture that, together
with the measured data, can be used to restrict the kinematical range of its

710.2799 | Study of the topological vacuum structure of SU(2) gluodynamics at T > 0
with overlap fermions and improved action | We study SU(2) gluodynamics at finite temperature near the deconfining phase
transition. We create the lattice ensembles using the tadpole improved
Luscher-Weisz action. The overlap Dirac operator is used to determine the
following three aspects of vacuum structure: (i) The topological susceptibility
is evaluated at various temperatures across the phase transition, (ii) the
overlap fermion spectral density is determined and found to depend on the

710.2801 | Multi-Gap Superconductivity in MgB2: Magneto-Raman Spectroscopy | Electronic Raman scattering studies on MgB2 single crystals as a function of
excitation and polarization have revealed three distinct superconducting
features: a clean gap below 37 cm-1 and two coherence peaks at 109 cm-1 and 78
cm-1 which we identify as the superconducting gaps in \pi- and \sigma-bands and
as the Leggett's collective mode arising from the fluctuation in the relative
phase between two superconducting condensates residing on corresponding bands.
The temperature and field dependencies of the superconducting features have
been established. A phononic Raman scattering study of the E2g boron stretching
mode anharmonicity and of superconductivity induced self-energy effects is
presented. We show that anharmonic two phonon decay is mainly responsible for
the unusually large linewidth of the E2g mode. We observe ~2.5% hardening of
the E2g phonon frequency upon cooling into the superconducting state and
estimate the electron-phonon coupling strength associated with this
renormalization.

710.2802 | Investigation of Strongly Correlated Electron Systems with Cellular
Dynamical Mean Field Theory | In this thesis we study the strongly-correlated-electron physics of the
longstanding H-Tc-superconductivity problem using a non-perturbative method,
the Dynamical Mean Field Theory (DMFT), capable to go beyond standard
perturbation-theory techniques. DMFT is by construction a local theory which
neglects spatial correlation. Experiments have however shown that the latter is
a fundamental property of cuprate materials. In a first step, we approach the
problem of spatial correlation in the normal state of cuprate materials using a
phenomenological Fermi-Liquid-Boltzmann model. We then introduce and develop in
detail an extension to DMFT, the Cellular Dynamical Mean Field Theory (CDMFT),
capable of considering short-ranged spatial correlation in a system, and we
implement it using the exact diagonalization algorithm . After benchmarking
CDMFT with the exact one-dimensional solution of the Hubbard Model, we employ
it to study the density-driven Mott metal-insulator transition in the
two-dimensional Hubbard Model, focusing in particular on the anomalous
properties of the doped normal state close to the Mott insulator. We finally
study the superconducting state. We show that within CDMFT the one-band Hubbard
Model supports a d-wave superconductive state, which strongly departs from the
standard BCS theory. We conjecture a link between the instabilities found in
the normal state and the onset of superconductivity.

710.2804 | Inelastic soliton processes generated by the perturbed KdV equation | Perturbations commonly added to the KdV equation contain terms that represent
inelastic interac-tions among KdV solitons in multiple-soliton solutions. These
terms trigger the emergence of new waves in the first-order correction to the
solution of the perturbed equation. The new waves can represent

710.2805 | Nouvelle analyse des ph\'enom\`enes vibratoires en tournage | In the cutting process, machine-tools vibrations are generally a real problem
when the amplitude crosses the limits of dimensional or surface quality
workpiece precision required. It is necessary to develop models taking into
account the three-dimensional vibratory approach to control the vibrations
phenomena. An experimental study has been realized to understand the behavior
of the cutting system and to identify its vibrations properties. The
displacement's localization of the tool in a spatial plan, showed by the
experimental results, allows us to simplify the three-dimensional dynamical
model. In this study, the experimental approach is completely presented and the
first points of the three dimensional vibratory model are proposed according to
the experimental results.

710.2806 | Direct measurement of the coherence length of edge states in the Integer
Quantum Hall Regime | We have determined the finite temperature coherence length of edge states in
the Integer Quantum Hall Effect (IQHE) regime. This was realized by measuring
the visibility of electronic Mach-Zehnder interferometers of different sizes,
at filling factor 2. The visibility shows an exponential decay with the
temperature. The characteristic temperature scale is found inversely
proportional to the length of the interferometer arm, allowing to define a
coherence length $\l_\phi$. The variations of $\l_\phi$ with magnetic field are
the same for all samples, with a maximum located at the upper end of the
quantum hall plateau. Our results provide the first accurate determination of
$\l_\phi$ in the quantum Hall regime.

710.2807 | Metal-rich debris discs around white dwarfs | We have identified two moderately hot (~18000-22000K) white dwarfs,
SDSSJ1228+1040 and SDSSJ1043+0855, which exhibit double-peaked emission lines
in the CaII 8600A triplet. These line profiles are unambiguous signatures of
gaseous discs with outer radii of ~1Rsun orbiting the two white dwarfs. Both
stars accrete from the circumstellar material, resulting in large photospheric
Mg abundances. The absence of hydrogen emission from the discs, and helium
absorption in the white dwarf photospheres demonstrates that the circumstellar
material is depleted in volatile elements, and the most likely origin of these
gaseous rings are tidally disrupted rocky asteroids. The relatively high mass

environment specific substitution tables | Environment specific substitution tables have been used effectively for
distinguishing structural and functional constraints on proteins and thereby
identify their active sites (Chelliah et al. (2004)). This work explores
whether a similar approach can be used to identify specificity determining
residues (SDRs) responsible for cofactor dependence, substrate specificity or
subtle catalytic variations. We combine structure-sequence information and
functional annotation from various data sources to create structural alignments
for homologous enzymes and functional partitions therein. We develop a scoring
procedure to predict SDRs and assess their accuracy using information from
bound specific ligands and published literature.

studying tau --> K_S pi nu_tau decay, which is significantly different from the
current world average value given by Particle Data Group 2006. Motivated by
this new data, we revisit the issue on the K*0(892)-K*+(892) mass splitting.
Our theoretical estimation favors the new measurement by Belle Collaboration.

710.2811 | Charge disproportionation and collinear magnetic order in the frustrated
triangular antiferromagnet AgNiO2 | We report a high-resolution neutron diffraction study of the crystal and
magnetic structure of the orbitally-degenerate frustrated metallic magnet
AgNiO2. At high temperatures the structure is hexagonal with a single
crystallographic Ni site, low-spin Ni3+ with spin-1/2 and two-fold orbital
degeneracy, arranged in an antiferromagnetic triangular lattice with frustrated
spin and orbital order. A structural transition occurs upon cooling below 365 K
to a tripled hexagonal unit cell containing three crystallographically-distinct
Ni sites with expanded and contracted NiO6 octahedra, naturally explained by
spontaneous charge order on the Ni triangular layers. No Jahn-Teller
distortions occur, suggesting that charge order occurs in order to lift the
orbital degeneracy. Symmetry analysis of the inferred Ni charge order pattern
and the observed oxygen displacement pattern suggests that the transition could
be mediated by charge fluctuations at the Ni sites coupled to a soft oxygen
optical phonon breathing mode. At low temperatures the electron-rich Ni
sublattice (assigned to a valence close to Ni2+ with S = 1) orders magnetically
into a collinear stripe structure of ferromagnetic rows ordered
antiferromagnetically in the triangular planes. We discuss the stability of
this uncommon spin order pattern in the context of an easy-axis triangular
antiferromagnet with additional weak second neighbor interactions and
interlayer couplings.

710.2813 | A Search for Mid-Infrared Molecular Hydrogen Emission from
Protoplanetary Disks | We observed the Herbig Ae/Be stars UX Ori, HD 34282, HD 100453, HD 101412, HD
104237 and HD 142666, and the T Tauri star HD 319139 and searched for H2 0-0
S(2) emission at 12.278 micron and H2 0-0 S(1) emission at 17.035 micron with
VISIR, ESO-VLT's high-resolution MIR spectrograph. None of the sources present
evidence for H2 emission. Stringent 3sigma upper limits to the integrated line
fluxes and the mass of optically thin warm gas in the disks are derived. The
disks contain less than a few tenths of Jupiter mass of optically thin H2 gas
at 150 K at most, and less than a few Earth masses of optically thin H2 gas at
300 K and higher temperatures. We compare our results to a Chiang and Goldreich
(1997, CG97) two-layer disk model. The upper limits to the disk's optically
thin warm gas mass are smaller than the amount of warm gas in the interior
layer of the disk, but they are much larger than the amount of molecular gas in
the surface layer. We present a calculation of the expected thermal H2 emission
from optically thick disks, assuming a CG97 disk structure, a gas-to-dust ratio
of 100 and Tgas = Tdust. The expected H2 thermal emission fluxes from typical
disks around Herbig Ae/Be stars (10^-16 to 10^-17 erg/s/cm2 at 140 pc) are much
lower than the detection limits of our observations (5*10^-15 erg/s/cm2). H2
emission levels are very sensitive to departures from the thermal coupling
between the molecular gas and dust. Additional sources of heating of gas in the
disk's surface layer could have a major impact on the expected H2 disk
emission. In the observed sources the molecular gas and dust in the surface
layer have not significantly departed from thermal coupling (Tgas/Tdust< 2) and
that the gas-to-dust ratio in the surface layer is very likely lower than 1000.

710.2814 | CO abundances in a protostellar cloud: freeze-out and desorption in the
envelope and outflow of L483 | CO isotopes are able to probe the different components in protostellar
clouds. These components, core, envelope and outflow have distinct physical
conditions and sometimes more than one component contributes to the observed
line profile. In this study we determine how CO isotope abundances are altered
by the physical conditions in the different components. We use a 3D molecular
line transport code to simulate the emission of four CO isotopomers, 12CO
J=2-1, 13CO J=2-1, C18O J=2-1 and C17O J=2-1 from the Class 0/1 object L483,
which contains a cold quiescent core, an infalling envelope and a clear
outflow. Our models replicate JCMT (James Clerk Maxwell Telescope) line
observations with the inclusion of freeze-out, a density profile and infall.
Our model profiles of 12CO and 13CO have a large linewidth due to a high
velocity jet. These profiles replicate the process of more abundant material

710.2815 | Optical emission from massive donors in ULX binary systems | We present evolutionary tracks of binary systems with high mass companion
stars and stellar-through-intermediate mass BHs. Using Eggleton's stellar
evolution code, we compute the luminosity produced by accretion from the donor
during its entire evolution. We compute also the evolution of the optical
spectrum of the binary system taking the disc contribution and irradiation
effects into account. The calculations presented here can be used to constrain
the properties of the donor stars in Ultraluminous X-ray Sources by comparing
their position on the HR or color-magnitude diagrams with the evolutionary
tracks of massive BH binaries. This approach may actually provide interesting
clues also on the properties of the binary system itself, including the BH
mass. We found that, on the basis of their position on the color-magnitude
diagram, some of the candidate counterparts considered can be ruled out and
more stringent constraints can be applied to the donor masses.

710.2816 | A classification of some Finsler connections and their applications | Some general Finsler connections are defined. Emphasis is being made on the
Cartan tensor and its derivatives. Vanishing of the hv-curvature tensors of
these connections characterizes Landsbergian, Berwaldian as well as Riemannian
structures. This view point makes it possible to give a smart representation of
connection theory in Finsler geometry and yields to a classification of Finsler

710.2819 | Fractional diffusion equation for aging and equilibrated random walks | We consider continuous time random walks (CTRW) and discuss situations
pertinent to aging. These correspond to the case when the initial state of the
system is known not at preparation (at $t=0$) but at the later instant of time
$t_1>0$ (intermediate-time initial condition). We derive the generalized aging
diffusion equation for this case and express it through a single memory kernel.
The results obtained are applied to the practically relevant case of the
equilibrated random walks. We moreover discuss some subtleties in the setup of
the aging subdiffusion problem and show that the behavior of the system depends
on what was taken as the intermediate-time initial condition: whether it was
coordinate of one particle given by measurement or the whole probability
distribution. The two setups lead to different predictions for the evolution of

transitions between confined light modes in properly modulated multimode
waveguides. The phenomenon is shown to take place in both, the linear and the

only in simple geometries, but also in complex confining multimode structures.
The phenomenon is analogous to the familiar stimulated state transitions that

The space of stable maps $\bar{\mathcal{M}}_{0,k}(X,d)$ carries different real
structures induced by $c_X$ and any order two element $\tau$ of permutation
group $S_k$ acting on marked points. Each corresponding real part
$\R_{\tau}\bar{\mathcal{M}}_{0,k}(X,d)$ is a real normal projective variety. As
the singular locus is of codimension bigger than two, these spaces thus carry a
first Stiefel-Whitney class for which we determine a representative in the case
$k=c_1(X)d-1$ where $c_1(X)$ is the first Chern class of $X$. Namely, we give a
homological description of these classes in term of the real part of boundary

710.2822 | SFitter: Reconstructing the MSSM Lagrangian from LHC data | Once supersymmetry is found at the LHC, the question arises what are the
fundamental parameters of the Lagrangian. The answer to this question should
thereby not be biased by assumptions on high-scale models. SFitter is a tool
designed for this task. Taking LHC (and possibly ILC) data as input it scans
the TeV-scale MSSM parameter space using its new weighted Markov chain
technique. Using this scan it determines a list of best-fitting parameter
points. Additionally a log-likelihood map is calculated, which can be reduced
to lower-dimensional Frequentist's profile likelihoods or Bayesian probability
maps.

710.2823 | On the Whitehead spectrum of the circle | The seminal work of Waldhausen, Farrell and Jones, Igusa, and Weiss and
Williams shows that the homotopy groups in low degrees of the space of
homeomorphisms of a closed Riemannian manifold of negative sectional curvature
can be expressed as a functor of the fundamental group of the manifold. To
determine this functor, however, it remains to determine the homotopy groups of
the topological Whitehead spectrum of the circle. The cyclotomic trace of B
okstedt, Hsiang, and Madsen and a theorem of Dundas, in turn, lead to an
expression for these homotopy groups in terms of the equivariant homotopy
groups of the homotopy fiber of the map from the topological Hochschild
T-spectrum of the sphere spectrum to that of the ring of integers induced by
the Hurewicz map. We evaluate the latter homotopy groups, and hence, the
homotopy groups of the topological Whitehead spectrum of the circle in low

| math.AT math.KT | the seminal work of waldhausen farrell and jones igusa and weiss and williams shows that the homotopy groups in low degrees of the space of homeomorphisms of a closed riemannian manifold of negative sectional curvature can be expressed as a functor of the fundamental group of the manifold to determine this functor however it remains to determine the homotopy groups of the topological whitehead spectrum of the circle the cyclotomic trace of b okstedt hsiang and madsen and a theorem of dundas in turn lead to an expression for these homotopy groups in terms of the equivariant homotopy groups of the homotopy fiber of the map from the topological hochschild tspectrum of the sphere spectrum to that of the ring of integers induced by the hurewicz map we evaluate the latter homotopy groups and hence the homotopy groups of the topological whitehead spectrum of the circle in low degrees the result extends earlier work by anderson and hsiang and by igusa and complements recent work by grunewald klein and macko | [['the', 'seminal', 'work', 'of', 'waldhausen', 'farrell', 'and', 'jones', 'igusa', 'and', 'weiss', 'and', 'williams', 'shows', 'that', 'the', 'homotopy', 'groups', 'in', 'low', 'degrees', 'of', 'the', 'space', 'of', 'homeomorphisms', 'of', 'a', 'closed', 'riemannian', 'manifold', 'of', 'negative', 'sectional', 'curvature', 'can', 'be', 'expressed', 'as', 'a', 'functor', 'of', 'the', 'fundamental', 'group', 'of', 'the', 'manifold', 'to', 'determine', 'this', 'functor', 'however', 'it', 'remains', 'to', 'determine', 'the', 'homotopy', 'groups', 'of', 'the', 'topological', 'whitehead', 'spectrum', 'of', 'the', 'circle', 'the', 'cyclotomic', 'trace', 'of', 'b', 'okstedt', 'hsiang', 'and', 'madsen', 'and', 'a', 'theorem', 'of', 'dundas', 'in', 'turn', 'lead', 'to', 'an', 'expression', 'for', 'these', 'homotopy', 'groups', 'in', 'terms', 'of', 'the', 'equivariant', 'homotopy', 'groups', 'of', 'the', 'homotopy', 'fiber', 'of', 'the', 'map', 'from', 'the', 'topological', 'hochschild', 'tspectrum', 'of', 'the', 'sphere', 'spectrum', 'to', 'that', 'of', 'the', 'ring', 'of', 'integers', 'induced', 'by', 'the', 'hurewicz', 'map', 'we', 'evaluate', 'the', 'latter', 'homotopy', 'groups', 'and', 'hence', 'the', 'homotopy', 'groups', 'of', 'the', 'topological', 'whitehead', 'spectrum', 'of', 'the', 'circle', 'in', 'low', 'degrees', 'the', 'result', 'extends', 'earlier', 'work', 'by', 'anderson', 'and', 'hsiang', 'and', 'by', 'igusa', 'and', 'complements', 'recent', 'work', 'by', 'grunewald', 'klein', 'and', 'macko']] | [-0.20119793201419747, 0.05934957695033171, -0.11939188910626053, 0.05267993446059769, -0.07189553530631765, -0.10048691321363938, 0.03863187036975952, 0.2933572096351002, -0.3302462746675398, -0.25833319457403076, 0.06819356983760372, -0.219332905205582, -0.16977250804137883, 0.1798397718812339, -0.19461611263076997, -0.034736223092847594, 0.004397731257735619, 0.07333016450450357, -0.03458799516028237, -0.2687267004254127, 0.4434070186246009, 0.03233133416229282, 0.204491501872131, 0.09784489794401452, 0.061165534619552396, 0.0020482721073286875, -0.049136852468585686, -0.020209535172138464, -0.14815183674181753, 0.17756067906572884, 0.27374630740710665, 0.03324198165986066, 0.167781921609449, -0.33837372684502043, -0.16940055233759008, 0.14740451915644198, 0.12719504043759247, -0.006431941028928296, 0.014839271443807298, -0.35289513634606484, 0.10896592020678024, -0.17963655027727196, -0.10598226169878174, -0.08327131947347273, 0.07017997064672056, 0.01964845391921699, -0.15692671439388678, 0.004698814136818761, 0.1303075393453972, 0.13593364114473974, -0.07904747903480061, -0.05551592015572602, -0.09268429926652018, 0.15439100311015777, 0.041366436840256766, 0.062357778630463316, 0.1292012848287067, -0.09159195300296796, -0.14703356732414768, 0.37949097877190935, -0.08948590570417721, -0.13748567154730804, 0.12311816241015636, -0.19325455329713545, -0.18667841917513647, 0.16297905969743928, 0.016698215129075662, 0.15706188880860628, -0.002841567565199165, 0.21671125709621092, -0.10074239486961492, 0.056024853338298965, 0.12792318671875233, -0.03516890623584567, 0.11431528070741999, 0.030651174776721746, 0.10050290418456868, 0.14164014533092822, 0.009557866713120824, -0.020260217250324786, -0.26714131575343864, -0.2539554357118461, -0.14309612663436427, 0.13653687841447426, -0.10716041658330748, -0.18677866093847634, 0.45028035005366074, 0.0597363841564705, 0.17026730986600297, 0.1597482150952731, 0.2326293612076413, 0.016424321773922116, 0.04972696558182915, 0.001414789787737564, 0.18047519631883396, 0.28258479234673795, 0.007318642356299928, -0.1488809480506461, -0.07931106713520075, 0.25063275792802286] |

710.2825 | Spatially extended PAHs in circumstellar disks around T Tauri and Herbig
Ae stars | Our aim is to determine the presence and location of the emission from
polycyclic aromatic hydrocarbons (PAHs) towards low and intermediate mass young
stars with disks using large aperture telescopes.
VLT-VISIR N-band spectra and VLT-ISAAC and VLT-NACO L-band spectra of 29
sources are presented, spectrally resolving the 3.3, 8.6, 11.2, and 12.6 micron
PAH features. Spatial-extent profiles of the features and the continuum
emission are derived and used to associate the PAH emission with the disks. The
results are discussed in the context of recent PAH-emission disk models.
The 3.3, 8.6, and 11.2 micron PAH features are detected toward a small
fraction of the T Tauri stars, with typical upper limits between 1E-15 and
5E-17 W/m^2. All 11.2 micron detections from a previous Spitzer survey are
confirmed with (tentative) 3.3 micron detections, and both the 8.6 and the 11.2
micron features are detected in all PAH sources. For 6 detections, the spatial
extent of the PAH features is confined to scales typically smaller than
0.12-0.34'', consistent with the radii of 12-60 AU disks at their distances
(typically 150 pc). For 3 additional sources, WL 16, HD 100546, and TY CrA, one
or more of the PAH features are more extended than the hot dust continuum of
the disk, whereas for Oph IRS 48, the size of the resolved PAH emission is
confirmed as smaller than for the large grains. For HD 100546, the 3.3 micron
emission is confined to a small radial extent of 12 +- 3 AU, most likely
associated with the outer rim of the gap in this disk. Gaps with radii out to
10-30 AU may also affect the observed PAH extent for other sources. For both
Herbig Ae and T Tauri stars, the small measured extents of the 8.6 and 11.2
micron features are consistent with larger (>= 100 carbon atoms) PAHs.

710.2826 | Ferromagnetic resonance study of polycrystalline Fe_{1-x}V_x alloy thin
films | Ferromagnetic resonance has been used to study the magnetic properties and
magnetization dynamics of polycrystalline Fe$_{1-x}$V$_{x}$ alloy films with
$0\leq x < 0.7$. Films were produced by co-sputtering from separate Fe and V
targets, leading to a composition gradient across a Si substrate. FMR studies
were conducted at room temperature with a broadband coplanar waveguide at
frequencies up to 50 GHz using the flip-chip method. The effective
demagnetization field $4 \pi M_{\mathrm{eff}}$ and the Gilbert damping
parameter $\alpha$ have been determined as a function of V concentration. The
results are compared to those of epitaxial FeV films.

710.2828 | Fermionic representation for the ferromagnetic Kondo lattice model --
diagrammatic study of spin-charge coupling effects on magnon excitations | A purely fermionic representation is introduced for the ferromagnetic Kondo
lattice model which allows conventional diagrammatic tools to be employed to
study correlation effects. Quantum 1/S corrections to magnon excitations are
investigated using a systematic inverse-degeneracy expansion scheme which
incorporates correlation effects in the form of self-energy and vertex
corrections, while explicitly preserving the continuous spin-rotation symmetry.
Magnon self-energy is studied in the full range of interaction strength, and
shown to result in strong magnon damping and anomalous softening for zone

perturbation theory | The neutron-neutron scattering length a_nn provides a sensitive probe of
charge-symmetry breaking in the strong interaction. Here we summarize our
recent efforts to use chiral perturbation theory in order to systematically
relate a_nn to the shape of the neutron spectrum in the reaction pi- d --> n n
gamma. In particular we show how the chiral symmetry of QCD relates this
process to low-energy electroweak reactions such as p p --> d e+ nu_e. This
allows us to reduce the uncertainty in the extracted a_nn (mainly due to
short-distance physics in the two-nucleon system) by a factor of more than
three, to <0.05 fm. We also report first results on the impact that two-nucleon
mechanisms of chiral order P^4 have on the pi- d --> n n gamma neutron
spectrum.

710.2832 | Schr\"odinger operator with periodic plus compactly supported potentials
on the half-line | We consider the Schr\"odinger operator $H$ with a periodic potential $p$ plus
a compactly supported potential $q$ on the half-line. We prove the following
results: 1) a forbidden domain for the resonances is specified, 2) asymptotics
of the resonance-counting function is determined, 3) in each nondegenerate gap
$\g_n$ for $n$ large enough there is exactly an eigenvalue or an antibound
state, 4) the asymptotics of eigenvalues and antibound states are determined at
high energy, 5) the number of eigenvalues plus antibound states is odd $\ge 1$
in each gap,
6) between any two eigenvalues there is an odd number $\ge 1$ of antibound
states, 7) for any potential $q$ and for any sequences $(\s_n)_{1}^\iy, \s_n\in
\{0,1\}$ and $(\vk_n)_1^\iy\in \ell^2, \vk_n\ge 0$, there exists a potential
$p$ such that each gap length $|\g_n|=\vk_n, n\ge 1$ and $H$ has exactly $\s_n$
eigenvalues and $1-\s_n$ antibound state in each gap $\g_n\ne \es$ for $n$
large enough, 8) if unperturbed operator (at $q=0$) has infinitely many virtual
states, then for any sequence $(\s)_1^\iy, \s_n\in \{0,1\}$, there exists a

710.2834 | Fermion masses and neutrino mixing in an U(1)_H flavor symmetry model
with hierarchical radiative generation for light charged fermion masses | I report the analysis performed on fermion masses and mixing, including
neutrino mixing, within the context of a model with hierarchical radiative mass
generation mechanism for light charged fermions, mediated by exotic scalar
particles at one and two loops, respectively, meanwhile the neutrinos get
Majorana mass terms at tree level through the Yukawa couplings with two SU(2)_L
Higgs triplets. All the resulting mass matrices in the model, for the u, d, and
e fermion charged sectors, the neutrinos and the exotic scalar particles, are
diagonalized in exact analytical form. Quantitative analysis shows that this
model is successful to accommodate the hierarchical spectrum of masses and
mixing in the quark sector as well as the charged lepton masses. The lepton
mixing matrix, V_{PMNS}, is written completely in terms of the neutrino masses
m_1, m_2, and m_3. Large lepton mixing for \theta_{12} and \theta_{23} is
predicted in the range of values 0.7 \lesssim \sin^22\theta_{12}\lesssim 0.7772
and 0.87 \lesssim \sin^22\theta_{23} \lesssim 0.9023 by using 0.033 \lesssim
s_{13}^2 \lesssim 0.04. These values for lepton mixing are consistent with 3
\sigma allowed ranges provided by recent global analysis of neutrino data
oscillation. From \Delta m_{\text{sol}}^2 bounds, neutrino masses are predicted
in the range of values m_1 \thickapprox (1.706 - 2.494) x 10^{- 3} eV, m_2
\thickapprox (6.675 - 12.56) x 10^{- 3} eV, and m_3 \thickapprox (1.215 -
2.188) x 10^{- 2} eV, respectively. The above allowed lepton mixing leads to
the quak-lepton complementary relations \theta_{12}^{CKM} + \theta_{12}^{PMNS}

710.2836 | Topological entropies of equivalent smooth flows | Two flows defined on a smooth manifold are equivalent if there exists a
homeomorphism of the manifold that sends each orbit of one flow onto an orbit
of the other flow while preserving the time orientation. The topological
entropy of a flow is defined as the entropy of its time-1 map. While
topological entropy is an invariant for equivalent homeomorphisms, finite
non-zero topological entropy for a flow cannot be an invariant because its
value is affected by time reparameterization. However, 0 and $\infty$
topological entropy are invariants for equivalent flows without fixed points.
In equivalent flows with fixed points there exists a counterexample,
constructed by Ohno, showing that neither 0 nor $\infty$ topological entropy is
preserved by equivalence. The two flows constructed by Ohno are suspensions of
a transitive subshift and thus are not differentiable. Note that a
differentiable flow on a compact manifold cannot have $\infty$ entropy. These
facts led Ohno in 1980 to ask the following: "Is 0 topological entropy an
invariant for equivalent differentiable flows?"
In this paper, we construct two equivalent $C^\infty$ smooth flows with a
singularity, one of which has positive topological entropy while the other has
zero topological entropy. This gives a negative answer to Ohno's question in
the class $C^\infty$.

710.2837 | Overhauser effect in individual InP/GaInP dots | Sizable nuclear spin polarization is pumped in individual InP/GaInP dots in a
wide range of external magnetic fields B_ext=0-5T by circularly polarized
optical excitation. We observe nuclear polarization of up to ~40% at Bext=1.5T
and corresponding to an Overhauser field of ~1.2T. We find a strong feedback of
the nuclear spin on the spin pumping efficiency. This feedback, produced by the
Overhauser field, leads to nuclear spin bi-stability at low magnetic fields of
Bext=0.5-1.5T. We find that the exciton Zeeman energy increases markedly, when
the Overhauser field cancels the external field. This counter-intuitive result

710.2839 | Magnetic field evolution in neutron stars | Neutron stars contain persistent, ordered magnetic fields that are the
strongest known in the Universe. However, their magnetic fluxes are similar to
those in magnetic A and B stars and white dwarfs, suggesting that flux
conservation during gravitational collapse may play an important role in
establishing the field, although it might also be modified substantially by
early convection, differential rotation, and magnetic instabilities. The
equilibrium field configuration, established within hours (at most) of the
formation of the star, is likely to be roughly axisymmetric, involving both
poloidal and toroidal components. The stable stratification of the neutron star
matter (due to its radial composition gradient) probably plays a crucial role
in holding this magnetic structure inside the star. The field can evolve on
long time scales by processes that overcome the stable stratification, such as
weak interactions changing the relative abundances and ambipolar diffusion of
charged particles with respect to neutrons. These processes become more
effective for stronger magnetic fields, thus naturally explaining the magnetic
energy dissipation expected in magnetars, at the same time as the longer-lived,
weaker fields in classical and millisecond pulsars.

local part of the effective action, we argue that the issue of quadratic
divergences does not arise in a theory where exact conformal symmetry is only
broken by quantum effects. Conformal symmetry can thus replace low energy
supersymmetry as a possible guide towards stabilizing the weak scale and
solving the hierarchy problem, if (i) there are no intermediate scales between
the weak scale and the Planck scale, and (ii) the running couplings exhibit
neither Landau poles nor instabilities over this whole range of energies.

710.2843 | Relativistic time dilatation and the spectrum of electrons emitted by 33
TeV lead ions penetrating thin foils | We study the energy distribution of ultrarelativistic electrons produced when
a beam of 33 TeV Pb$^{81+}$(1s) ions penetrates a thin Al foil. We show that,
because of a prominent role of the excitations of the ions inside the foil
which becomes possible due to the relativistic time dilatation, the width of
this distribution can be much narrower compared to the case when the ions
interact with rarefied gaseous targets. We also show that a very similar shape
of the energy distribution may arise when 33 TeV Pb$^{82+}$ ions penetrate a

710.2844 | Does a particle swept by a turbulent liquid diffuse? | Since the famous 1926 paper by Richardson, the relative diffusion of two
particles in a turbulent liquid has attracted a lot of interest. The motion of
a single particle on the other hand is usually considered not to be especially
interesting. The widely accepted picture is that the velocity of the particle
has short-range correlations in time, resulting in motion that is diffusive on
time scales large compared to the correlation time. We find, however, that the
correlation time is infinite and that the square displacement, F, is not linear
in the traversed time, T, which would correspond to diffusion, but rather F is
proportional to T^6/5. Namely, the motion is slightly super diffusive.

transistors | Electronic transport through rubrene single-crystal field effect transistors
(FETs) is investigated experimentally in the high carrier density regime (n ~
0.1 carrier/molecule). In this regime, we find that the current does not
increase linearly with the density of charge carriers, and tends to saturate.
At the same time, the activation energy for transport unexpectedly increases
with increasing n. We perform a theoretical analysis in terms of a well-defined
microscopic model for interacting Frohlich polarons, that quantitatively
accounts for our experimental observations. This work is particularly
significant for our understanding of electronic transport through organic FETs.

Tevatron, it seems appropriate to have another look at the two-photon decay of
heavy quarkonium from the standpoint of an effective Lagrangian based on local
operator expansion and heavy-quark spin symmetry. In this talk, I would like to
discuss a recent work on the two-photon decay rates of ground states and
excited states of $\eta_c$ and $\eta_b$ using the local operator expansion
approach and heavy-quark spin symmetry and taking into account the
binding-energy. We find that the predicted two-photon width for $\eta_c$ agrees
well with experiment, but the predicted value for $\eta_c(2S)$ is twice larger
than the CLEO estimation. We point out that the essentially model-independent
ratio of $\eta_b$ two-photon width to the $\Upsilon$ leptonic width and the
$\eta_b $ two-photon width could be used to extract the strong coupling
constant $\alpha_s$ .

710.2847 | A synchrotron self-Compton scenario for the very high energy gamma-ray
emission of the radiogalaxy M87 | M87 is the first extragalactic source detected in the TeV range that is not a
blazar. With the increasing performances of ground-based Cherenkov telescopes,
we can now probe the variability in the gamma-ray flux at small timescales,
thus putting strong constraints on the size of the emitting zone. A
modification of standard emission models of TeV blazars appears necessary to
account for the gamma-ray observations despite this misalignment. We explain
TeV gamma-ray spectra and fast variability of M87 by invoking an emission zone
close to the central supermassive black hole, which is filled with several
plasma blobs moving in the large opening angle of the jet formation zone. We
develop a new multi-blob synchrotron self-Compton (SSC) model with emitting
blobs beyond the Alfven surface in the jet, at a distance of about 100 r_g from
the central engine. This model is explicitly adapted to deal with large viewing
angles and moderate values of the Lorentz factor inferred from (general
relativistic) magnetohydrodynamic models of jet formation. This scenario can
account for the recent gamma-ray observations of M87 made by the High Energy
Stereoscopic System (H.E.S.S.) telescope array. We find individual blob radii
of about 10^{14} cm, which is compatible with the variability on timescales of
days recently reported by the H.E.S.S. collaboration and is of the order of the
black hole gravitational radius. Predictions of the very high energy emission
for three other sources with extended optical or X-ray jet which could be
misaligned blazars still with moderate beaming are presented for one Seyfert 2
radiogalaxy, namely Cen A, one peculiar BL Lac, PKS 0521-36, and one quasar, 3C

710.2848 | Consistency of trace norm minimization | Regularization by the sum of singular values, also referred to as the trace
norm, is a popular technique for estimating low rank rectangular matrices. In
this paper, we extend some of the consistency results of the Lasso to provide
necessary and sufficient conditions for rank consistency of trace norm
minimization with the square loss. We also provide an adaptive version that is

710.285 | Local SU(5) Unification in 6D from the Heterotic String | We present a six-dimensional T^2/Z_2 orbifold model which arises as an
intermediate step in the compactification of the heterotic string to the MSSM.
The orbifold contains two pairs of inequivalent fixed points, with unbroken
local gauge groups SU(5) and SU(2)xSU(4), respectively, the intersection of
which gives the standard model gauge group. All bulk and brane anomalies are
cancelled by the Green--Schwarz mechanism. At each SU(5) fixed point, there is
a localised \bar{5}+10 standard model generation, while the third generation
and the Higgs fields come in split bulk multiplets due to the breaking of SU(5)
at the other fixed point.

710.2852 | Generating models for temporal representations | We discuss the use of model building for temporal representations. We chose
Polish to illustrate our discussion because it has an interesting aspectual
system, but the points we wish to make are not language specific. Rather, our
goal is to develop theoretical and computational tools for temporal model
building tasks in computational semantics. To this end, we present a
first-order theory of time and events which is rich enough to capture
interesting semantic distinctions, and an algorithm which takes minimal models
for first-order theories and systematically attempts to ``perturb'' their
temporal component to provide non-minimal, but semantically significant,
models.
