We propose relativistic Luttinger fermions as a new ingredient for the
construction of fundamental quantum field theories. We construct the
corresponding Clifford algebra and the spin metric for relativistic invariance
of the action using the spin-base invariant formalism. The corresponding
minimal spinor has 32 complex components, matching with the degrees of freedom
of a standard-model generation including a right-handed neutrino. The resulting
fermion fields exhibit a canonical scaling different from Dirac fermions and
thus support the construction of novel relativistic and perturbatively
renormalizable, interacting quantum field theories. In particular, new
asymptotically free self-interacting field theories can be constructed,
representing first examples of high-energy complete quantum field theories
based on pure matter degrees of freedom. Gauge theories with relativistic
Luttinger fermions exhibit a strong paramagnetic dominance, requiring large
nonabelian gauge groups to maintain asymptotic freedom. We comment on the
possibility to use Luttinger fermions for particle physics model building and
the expected naturalness properties of such models.

We consider the Yang-Mills equations for a matrix gauge group $G$ inside the
future light cone of 4-dimensional Minkowski space, which can be viewed as a
Lorentzian cone $C(H^3)$ over the 3-dimensional hyperbolic space $H^3$. Using
the conformal equivalence of $C(H^3)$ and the cylinder $R\times H^3$, we show
that, in the adiabatic limit when the metric on $H^3$ is scaled down, classical
Yang-Mills dynamics is described by geodesic motion in the infinite-dimensional
group manifold $C^\infty (S^2_\infty,G)$ of smooth maps from the boundary
2-sphere $S^2_\infty=\partial H^3$ into the gauge group $G$.

A long-standing debate on Unruh effect is about its obscure thermal nature.
In this Letter, we use quantum Fisher information (QFI) as an effective probe
to explore the thermal nature of Unruh effect from both local and global
perspectives. By resolving the full dynamics of UDW detector, we find that the
QFI is a time-evolving function of detector's energy gap, Unruh temperature
$T_U$ and particularities of background field, e.g., mass and spacetime
dimensionality. We show that the asymptotic QFI whence detector arrives its
equilibrium is solely determined by $T_U$, demonstrating the global side of
Unruh thermality alluded by the KMS condition. We also show that the local side
of Unruh effect, i.e., the different ways for the detector to approach the same
thermal equilibrium, is encoded in the corresponding time-evolution of the QFI.
In particular, we find that with massless scalar background the QFI has unique
monotonicity in $n=3$ dimensional spacetime, and becomes non-monotonous for
$n\neq3$ models where a local peak value exists at early time and for finite
acceleration, indicating an enhanced precision of estimation on Unruh
temperature at a relative low acceleration can be achieved. Once the field
acquiring mass, the related QFI becomes significantly robust against the Unruh
decoherence in the sense that its local peak sustains for a very long time.
While coupling to a more massive background, the persistence can even be
strengthened and the QFI possesses a larger maximal value. Such robustness of
QFI can surely facilitate any practical quantum estimation task.

We describe D=4 twistorial membrane in terms of two twistorial
three-dimensional world volume fields. We start with the D-dimensional p-brane
generalizations of two phase space string formulations: the one with $p+1$
vectorial fourmomenta, and the second with tensorial momenta of $(p+1)$-th
rank. Further we consider tensionful membrane case in D=4. By using the
membrane generalization of Cartan-Penrose formula we express the fourmomenta by
spinorial fields and obtain the intermediate spinor-space-time formulation.
Further by expressing the worldvolume dreibein and the membrane space-time
coordinate fields in terms of two twistor fields one obtains the purely
twistorial formulation. It appears that the action is generated by a geometric
three-form on two-twistor space. Finally we comment on higher-dimensional (D>4)
twistorial p-brane models and their superextensions.

Non--Abelian duality in relation to supersymmetry is examined. When the
action of the isometry group on the complex structures is non--trivial,
extended supersymmetry is realized non--locally after duality, using path
ordered Wilson lines. Prototype examples considered in detail are,
hyper--Kahler metrics with SO(3) isometry and supersymmetric WZW models. For
the latter, the natural objects in the non--local realizations of supersymmetry
arising after duality are the classical non--Abelian parafermions. The
canonical equivalence of WZW models and their non--Abelian duals with respect
to a vector subgroup is also established.

deformed multiplication operation on a quasitriangular Hopf algebra in terms of
its R-matrix, and comment on some of its properties. We show that the
noncommutative string theory *-product is a particular example of this
multiplication, and comment on other possible Hopf algebraic properties which

We show by direct construction that a large class of quiver gauge theories
admits actions of finite Heisenberg groups. We consider various quiver gauge
theories that arise as AdS/CFT duals of orbifolds of C^3, the conifold and its
orbifolds and some orbifolds of the cone over Y(p,q). Matching the gauge theory
analysis with string theory on the corresponding spaces implies that the
operators counting wrapped branes do not commute in the presence of flux.

We present the geodesical completion of the Schwarzschild black hole in four
dimensions which covers the entire space in (u,v) Kruskal-Szekeres coordinates,
including the spacetime behind the black and white hole singularities. The
gravitational constant switches sign abruptly at the singularity, thus we
interpret the other side of the singularity as a region of antigravity. The
presence of such sign flips is a prediction of local (Weyl) scale invariant
geodesically complete spacetimes which improve classical general relativity and
string theory. We compute the geodesics for our new black hole and show that
all geodesics of a test particle are complete. Hence, an ideal observer, that
starts its journey in the usual space of gravity, can reach the other side of
the singularity in a finite amount of proper time. As usual, an observer
outside of the horizon cannot verify that such phenomena exist. However, the
fact that there exist proper observers that can see this, is of fundamental
significance for the construction of the correct theory and the interpretation
of phenomena pertaining to black holes and cosmology close to and beyond the
singularities.

We analytically evaluate the moments of the spectral density of the $q$-body
Sachdev-Ye-Kitaev (SYK) model, and obtain order $1/N^2$ corrections for all
moments, where $N$ is the total number of Majorana fermions. To order $1/N$,
moments are given by those of the weight function of the Q-Hermite polynomials.
Representing Wick contractions by rooted chord diagrams, we show that the
$1/N^2$ correction for each chord diagram is proportional to the number of
triangular loops of the corresponding intersection graph, with an extra grading
factor when $q$ is odd. Therefore the problem of finding $1/N^2$ corrections is
mapped to a triangle counting problem. Since the total number of triangles is a
purely graph-theoretic property, we can compute them for the $q=1$ and $q=2$
SYK models, where the exact moments can be obtained analytically using other
methods, and therefore we have solved the moment problem for any $q$ to $1/N^2$
accuracy. The moments are then used to obtain the spectral density of the SYK
model to order $1/N^2$. We also obtain an exact analytical result for all
contraction diagrams contributing to the moments, which can be evaluated up to
eighth order. This shows that the Q-Hermite approximation is accurate even for
small values of $N$.

We argue that all consistent 4D quantum field theories obey a
spacetime-averaged weak energy inequality $\langle T^{00} \rangle \ge -C/L^4$,
where $L$ is the size of the smearing region, and $C$ is a positive constant
that depends on the theory. If this condition is violated, the theory has
states that are indistinguishable from states of negative total energy by any
local measurement, and we expect instabilities or other inconsistencies. We
apply this condition to 4D conformal field theories, and find that it places
constraints on the OPE coefficients of the theory. The constraints we find are
weaker than the "conformal collider" constraints of Hofman and Maldacena. We
speculate that there may be theories that violate the Hofman-Maldacena bounds,
but satisfy our bounds. In 3D CFTs, the only constraint we find is equivalent
to the positivity of 2-point function of the energy-momentum tensor, which
follows from unitarity. Our calculations are performed using momentum-space
Wightman functions, which are remarkably simple functions of momenta, and may
be of interest in their own right.

We use Chen iterated line integrals to construct a topological algebra ${\cal
A}_p$ of separating functions on the {\it Group of Loops} ${\bf L}{\cal M}_p$.
${\cal A}_p$ has an Hopf algebra structure which allows the construction of a
group structure on its spectrum. We call this topological group, the group of
generalized loops $\widetilde {{\bf L}{\cal M}_p}$.
Then we develope a {\it Loop Calculus}, based on the {\it Endpoint} and {\it
Area Derivative Operators}, providing a rigorous mathematical treatment of
early heuristic ideas of Gambini, Trias and also Mandelstam, Makeenko and
Migdal. Finally we define a natural action of the "pointed" diffeomorphism
group $Diff_p({\cal M})$ on $ \widetilde {{\bf L}{\cal M}_p}$, and consider a
{\it Variational Derivative} which allows the construction of homotopy
invariants.
This formalism is useful to construct a mathematical theory of {\it Loop
Representation} of Gauge Theories and Quantum Gravity. Figures available by

We perform a detailed phase-space analysis of Horava-Lifshitz cosmology, with
and without the detailed-balance condition. Under detailed-balance we find that
the universe can reach a bouncing-oscillatory state at late times, in which
dark-energy, behaving as a simple cosmological constant, is dominant. In the
case where the detailed-balance condition is relaxed, we find that the universe
reaches an eternally expanding, dark-energy-dominated solution, with the
oscillatory state preserving also a small probability. Although this analysis
indicates that Horava-Lifshitz cosmology can be compatible with observations,
it does not enlighten the discussion about its possible conceptual and
theoretical problems.

We consider a complex scalar field in (p+3)-dimensional bulk with a negative
cosmological constant and study global vortices in two extra-dimensions. We
reexamine carefully the coupled scalar and Einstein equations, and show that
the boundary value of scalar amplitude at infinity of the extra-dimensions
should be smaller than vacuum expectation value. The brane world has a
cigar-like geometry with an exponentially decaying warp factor and a flat thick
p-brane is embedded. Since a coordinate transformation identifies the obtained
brane world as a black p-brane world bounded by a horizon, this strange
boundary condition of the scalar amplitude is understood as existence of a
short scalar hair.

We compute the capacity of entanglement in the bipartite random pure state
model using the replica method. We find the exact expression of the capacity of
entanglement which is valid for a finite dimension of the Hilbert space. We
argue that in the gravitational path integral, the capacity of entanglement
receives contributions only from the sub-leading saddle points corresponding to
the partially connected geometries.

The black hole information paradox forces us into a strange situation: we
must find a way to break the semiclassical approximation in a domain where no
quantum gravity effects would normally be expected. Traditional quantizations
of gravity do not exhibit any such breakdown, and this forces us into a
difficult corner: either we must give up quantum mechanics or we must accept
the existence of troublesome `remnants'. In string theory, however, the
fundamental quanta are extended objects, and it turns out that the bound states
of such objects acquire a size that grows with the number of quanta in the
bound state. The interior of the black hole gets completely altered to a
`fuzzball' structure, and information is able to escape in radiation from the
hole. The semiclassical approximation can break at macroscopic scales due to
the large entropy of the hole: the measure in the path integral competes with
the classical action, instead of giving a subleading correction. Putting this
picture of black hole microstates together with ideas about entangled states
leads to a natural set of conjectures on many long-standing questions in
gravity: the significance of Rindler and de Sitter entropies, the notion of
black hole complementarity, and the fate of an observer falling into a black
hole.

The black hole information paradox forces us into a strange situation: we must find a way to break the semiclassical approximation in a domain where no quantum gravity effects would normally be expected. Traditional quantizations of gravity do not exhibit any such breakdown, and this forces us into a difficult corner: either we must give up quantum mechanics or we must accept the existence of troublesome `remnants'. In string theory, however, the fundamental quanta are extended objects, and it turns out that the bound states of such objects acquire a size that grows with the number of quanta in the bound state. The interior of the black hole gets completely altered to a `fuzzball' structure, and information is able to escape in radiation from the hole. The semiclassical approximation can break at macroscopic scales due to the large entropy of the hole: the measure in the path integral competes with the classical action, instead of giving a subleading correction. Putting this picture of black hole microstates together with ideas about entangled states leads to a natural set of conjectures on many long-standing questions in gravity: the significance of Rindler and de Sitter entropies, the notion of black hole complementarity, and the fate of an observer falling into a black hole.

The gauged sigma-model argument that string backgrounds related by T-dual
give equivalent quantum theories is revisited, taking careful account of global
considerations. The topological obstructions to gauging sigma-models give rise
to obstructions to T-duality, but these are milder than those for gauging: it
is possible to T-dualise a large class of sigma-models that cannot be gauged.
For backgrounds that are torus fibrations, it is expected that T-duality can be
applied fibrewise in the general case in which there are no globally-defined
Killing vector fields, so that there is no isometry symmetry that can be
gauged; the derivation of T-duality is extended to this case. The T-duality
transformations are presented in terms of globally-defined quantities. The
generalisation to non-geometric string backgrounds is discussed, the conditions
for the T-dual background to be geometric found and the topology of T-folds
analysed.

We consider the two most general families of the (1+1)D Dirac systems with
transparent scalar potentials, and two related families of the paired
reflectionless Schrodinger operators. The ordinary N=2 supersymmetry for such
Schrodinger pairs is enlarged up to an exotic N=4 nonlinear centrally extended
supersymmetric structure, which involves two bosonic integrals composed from
the Lax-Novikov operators for the stationary Korteweg-de Vries hierarchy. Each
associated single Dirac system displays a proper N=2 nonlinear supersymmetry
with a non-standard grading operator. One of the two families of the first and
second order systems exhibits the unbroken supersymmetry, while another is
described by the broken exotic supersymmetry. The two families are shown to be
mutually transmuted by applying a certain limit procedure to the soliton
scattering data. We relate the topologically trivial and nontrivial transparent
potentials with self-consistent inhomogeneous condensates in Bogoliubov-de
Gennes and Gross-Neveu models, and indicate the exotic N=4 nonlinear
supersymmetry of the paired reflectionless Dirac systems.

We show that the noncommutative Wess-Zumino model is renormalizable to all
orders of perturbation theory. The noncommutative scalar potential by itself is
non-renormalizable but the Yukawa terms demanded by supersymmetry improve the
situation turning the theory into a renormalizable one. As in the commutative
case, there are neither quadratic nor linear divergences. Hence, the IR/UV
mixing does not give rise to quadratic infrared poles.

A derivation of N=1 supergravity action from string theory is presented.
Starting from a Nambu-Goto bosonic string, matter field is introduced to obtain
a superstring in four dimension. The excitation quanta of this string contain
graviton and the gravitino. Using the principle of equivalence, the action in
curved space time are found and the sum of them is the Deser-Zumino N=1
supergravity action. The energy tensor is Lorentz invariant due to
supersymmetry.

We present and discuss near horizon boundary conditions for flat space
higher-spin gravity in three dimensions. As in related work our boundary
conditions ensure regularity of the solutions independently of the charges. The
asymptotic symmetry algebra is given by a set of $\hat{\mathfrak{u}}(1)$
current algebras. The associated charges generate higher-spin soft hair. We
derive the entropy for solutions that are continuously connected to flat space
cosmologies and find the same result as in the spin-2 case: the entropy is
linear in the spin-2 zero-mode charges and independent from the spin-3 charges.
Using twisted Sugawara-like constructions of higher-spin currents we show that
our simple result for entropy of higher-spin flat space cosmologies coincides
precisely with the complicated earlier results expressed in terms of
higher-spin zero mode charges.

We consider the noncommutative space $\mathbb{R}^3_\lambda$, a deformation of
the algebra of functions on $\mathbb{R}^3$ which yields a "foliation" of
$\mathbb{R}^3$ into fuzzy spheres. We first construct a natural matrix base
adapted to $\mathbb{R}^3_\lambda$. We then apply this general framework to the
one-loop study of a two-parameter family of real-valued scalar noncommutative
field theories with quartic polynomial interaction, which becomes a non-local
matrix model when expressed in the above matrix base. The kinetic operator
involves a part related to dynamics on the fuzzy sphere supplemented by a term
reproducing radial dynamics. We then compute the planar and non-planar 1-loop
contributions to the 2-point correlation function. We find that these diagrams
are both finite in the matrix base. We find no singularity of IR type, which
signals very likely the absence of UV/IR mixing. We also consider the case of a
kinetic operator with only the radial part. We find that the resulting theory
is finite to all orders in perturbation expansion.

non-restricted extensions of the isometry algebras to geometric superalgebras.
Both families admit points for which the superalgebra extends to a super Lie
algebra; on the one hand, a family of $N=1$, $\nu={}^3\!/\!_4$ supergravity
backgrounds and, on the other hand, a family of $N=1$, $\nu=1$ supergravity
background. Furthermore, both families admit a point that can be identified
with an $N=4$, $\nu={}^1\!/\!_2$ six-dimensional supergravity background.

We prove that a class of solutions to Einstein's equations---originally
discovered by G. C. McVittie in 1933---includes regular black holes embedded in
Friedman-Robertson-Walker cosmologies. If the cosmology is dominated at late
times by a positive cosmological constant, the metric is regular everywhere on
and outside the black hole horizon and away from the big bang singularity, and
the solutions asymptote in the future and near the horizon to the
Schwarzschild-de Sitter geometry. For solutions without a positive cosmological
constant the would-be horizon is a weak null singularity.

We prove that a class of solutions to Einstein's equations---originally discovered by G. C. McVittie in 1933---includes regular black holes embedded in Friedman-Robertson-Walker cosmologies. If the cosmology is dominated at late times by a positive cosmological constant, the metric is regular everywhere on and outside the black hole horizon and away from the big bang singularity, and the solutions asymptote in the future and near the horizon to the Schwarzschild-de Sitter geometry. For solutions without a positive cosmological constant the would-be horizon is a weak null singularity.

Quantum field theories with identical local dynamics can admit different
choices of global structure, leading to different partition functions and
spectra of extended operators. Such choices can be reformulated in terms of a
topological field theory in one dimension higher, the symmetry TFT. In this
paper we show that this TFT can be reconstructed from a careful analysis of the
infrared Coulomb-like phases. In particular, the TFT matches between the UV and
the IR. This provides a purely field theoretical counterpart of several recent
results obtained via geometric engineering in various string/M/F theory setups
for theories in four and five dimensions that we confirm and extend.

We review the correspondence between effective actions resulting from
non-invariant Lagrangian densities, for Goldstone bosons arising from
spontaneous breakdown of a symmetry group G to a subgroup H, and non-trivial
generators of the de Rham cohomology of G/H. We summarize the construction of
cohomology generators in terms of symmetric tensors with certain invariance and
vanishing properties with respect to G and H. The resulting actions in four
dimensions arise either from products of generators of lower degree such as the
Goldstone-Wilczek current, or are of the Wess-Zumino-Witten type. Actions in
three dimensions arise as Chern-Simons terms evaluated on composite gauge
fields and may induce fractional spin on solitons. {Contribution to the
Proceedings of STRINGS 95, held at University of Southern California, March 13

A formula is derived that allows the computation of one-loop mass shifts for
self-dual semilocal topological solitons. These extended objects, which in
three spatial dimensions are called semi-local strings, arise in a generalized
Abelian Higgs model with a doublet of complex Higgs fields. Having a mixture of
global, SU(2), and local (gauge), U(1), symmetries, this weird system may seem
bizarre, but it is in fact the bosonic sector of electro-weak theory when the
weak mixing angle is of 90 degrees. The procedure for computing the
semi-classical mass shifts is based on canonical quantization and heat
kernel/zeta function regularization methods.

We apply the methods of modern analytic bootstrap to the critical $O(N)$
model in a $1/N$ expansion. At infinite $N$ the model possesses higher spin
symmetry which is weakly broken as we turn on $1/N$. By studying consistency
conditions for the correlator of four fundamental fields we derive the CFT-data
for all the (broken) currents to order $1/N$, and the CFT-data for the
non-singlet currents to order $1/N^2$. To order $1/N$ our results are in
perfect agreement with those in the literature. To order $1/N^2$ we reproduce
known results for anomalous dimensions and obtain a variety of new results for
structure constants, including the global symmetry central charge $C_J$ to this
order.

In this paper we apply the formalism of local composite operators as
developed by Verschelde et al. in combination with a constant chromomagnetic
field as considered in the seventies by Savvidy and others. We find that a
nonzero <A_\mu^2> minimizes the vacuum energy, as in the case with no
chromomagnetic field, and that the chromomagnetic field itself is near-to zero.
The Nielsen-Olesen instability, caused by the imaginary part in the action,
also vanishes. We further investigate the effect of an external chromomagnetic
field on the value of <A_\mu^2>, finding that this condensate is destroyed by
sufficiently strong fields. The inverse scenario, where <A_\mu^2> is considered
as external, results in analogous findings: when this condensate is
sufficiently large, the induced chromomagnetic field is lowered to a
perturbative value slightly below the applied <A_\mu^2>.

We present a general method of computing corrections to the extremality bound
and entropy of Kerr-Newman black holes due to an arbitrary perturbation using
the Iyer-Wald formalism. In this method, corrections to the extremality bound
are given by an integral over an effective stress tensor which, in particular
cases of interest, reduces to the usual stress tensor. This clarifies the
relation between extremality corrections and energy conditions. In particular,
we show that a necessary condition to decrease the mass of an extremal black
hole in a canonical ensemble, as required by the weak gravity conjecture, is
that the perturbation violates the dominant energy condition. As an application
of our method, we compute higher-derivative corrections to charged black holes
in anti-de Sitter space and Kerr black holes.

We generalize the Randall Sundrum warped braneworld model in six and higher
dimension and propose a resolution to the mass hierarchy among the standard
model fermions. The fine tuning problem in connection with the scalar mass
however is shown to reappear in a new guise in five dimensional warped model
when the two form antisymmetric tensor fields, a massless string mode,
propagates in the bulk. Finally the issue of modulus stabilization is
re-examined in presence of a bulk scalar by considering it's back-reaction on
the background geometry. The role of higher derivative term of the bulk scalar
is shown to be crucial to achieve modulus stabilization.

We give another reformulation of the Thirring model (with four-fermion
interaction of the current-current type) as a gauge theory and identify it with
a gauge-fixed version of the corresponding gauge theory according to the
Batalin-Fradkin formalism. Based on this formalism, we study the chiral
symmetry breaking of the $D$-dimensional Thirring model ($2<D<4$) with $N$
flavors of 4-component fermions. By constructing the gauge covariant effective
potential for the chiral order parameter, up to the leading order of $1/N$
expansion, we show the existence of the second order chiral phase transition
and obtain explicitly the critical number of flavors $N_c$ (resp. critical
four-fermion coupling $G_c$) as a function of the four-fermion coupling $G$
(resp. $N$), below (resp. above) which the chiral symmetry is spontaneously
broken.

We give another reformulation of the Thirring model (with four-fermion interaction of the current-current type) as a gauge theory and identify it with a gauge-fixed version of the corresponding gauge theory according to the Batalin-Fradkin formalism. Based on this formalism, we study the chiral symmetry breaking of the $D$-dimensional Thirring model ($2<D<4$) with $N$ flavors of 4-component fermions. By constructing the gauge covariant effective potential for the chiral order parameter, up to the leading order of $1/N$ expansion, we show the existence of the second order chiral phase transition and obtain explicitly the critical number of flavors $N_c$ (resp. critical four-fermion coupling $G_c$) as a function of the four-fermion coupling $G$ (resp. $N$), below (resp. above) which the chiral symmetry is spontaneously broken.

A new method for constructing flows between distinct Landau-Ginzburg theories
at fixed central charge is presented. The essential ingredient of the
construction is an enlarged moduli space obtained by adding theories with zero
central charge. The flows involve only marginal directions hence they can be
applied to transitions between string vacua, in particular to the construction
of mirror pairs of string ground states described by RG fixed points of N=2
supersymmetric Landau--Ginzburg theories. In contrast to previous methods this
new construction of mirror theories does not depend on particular symmetries of
the original theory.

The reduction of 4d matter-gravity theory to $S_2$, $H_2$ or $R_2$ leads to
effective 2d dilatonic gravity with dilaton coupled matter. Spinors give the
exceptional example of the theory which is conformally invariant in 4d as well
as in 2d, after reduction. We find 4d and 2d conformal anomaly induced
effective action (EA) for Majorana spinor. It is expected for some time that
s-wave EA (i.e. the one for dilaton coupled 2d matter) is some (s-wave)
approximation to 4d EA. We compare such 2d and 4d spinor EAs on the same
gravitational background and argue that s-wave EA indeed qualitatively
corresponds to no higher derivatives approximation for 4d EA.

The properties of the three-dimensional noncanonical osp(3/2) oscillators,
introduced in J.Phys. A: Math. Gen. {\bf 27} (1994) 977, are further studied.
The angular momentum M of the oscillators can take at most three values
M=p-1,p,p+1, which are either all integers or all half-integers. The
coordinates anticommute with each other. Depending on the state space the
energy spectrum can coincide or can be essentially different from those of the
canonical oscillator. The ground state is in general degenerated.

Recently exact agreement has been found between three-point correlators of
chiral operators computed in string theory on AdS_3 x S^3 x T^4 with NS-NS flux
and those computed in the symmetric orbifold CFT. However, it has also been
shown that these correlators disagree with those computed in supergravity,
under any identification of single particle operators which respects the
symmetries. In this note we resolve this disagreement: the key point is that
mixings with multi-particle operators are not suppressed even at large N in
extremal correlators. Allowing for such mixings, orbifold/string theory
operators and supergravity operators can be matched such that both non-extremal
and extremal three point functions agree, giving further evidence for the
non-renormalization of the chiral ring.

We consider the realization of N=2 superconformal models in terms of free
first-order $(b,c,\beta,\gamma)$-systems, and show that an arbitrary
Landau-Ginzburg interaction with quasi-homogeneous potential can be introduced
without spoiling the (2,2)-superconformal invariance. We discuss the
topological twisting and the renormalization group properties of these
theories, and compare them to the conventional topological Landau-Ginzburg
models. We show that in our formulation the parameters multiplying deformation
terms in the potential are flat coordinates. After properly bosonizing the
first-order systems, we are able to make explicit calculations of topological
correlation functions as power series in these flat coordinates by using
standard Coulomb gas techniques. We retrieve known results for the minimal
models and for the torus.

We investigate the thermodynamics of Einstein-Maxwell(-Dilaton) theory for an
asymptotically flat spacetime in a quasilocal frame. We firstly define a
quasilocal thermodynamic potential via the Euclidean on-shell action and
formulate a quasilocal Smarr relation from Eulerian theorem. Then we calculate
quasilocal energy and surface pressure by employing Brown-York quasilocal
method along with Mann-Marolf counterterm and find entropy from the quasilocal
thermodynamic potential. These quasilocal variables are consistent with Tolman
temperature and the entropy in a quasilocal frame turns out to be same as the
Bekenstein-Hawking entropy. As a result, we found that a surface pressure term
and its conjugate variable, a quasilocal area, do not participate in a
quasilocal thermodynamic potential, but should present in a quasilocal Smarr
relation and the quasilocal first law of black hole thermodynamics. For dyonic
black hole solutions having dynamic dilaton field, non-trivial dilaton
contribution should take part in the quasilocal first law but not in the
quasilocal Smarr relation.

auxiliary field method to the quantization of the Podolsky electrodynamics in
thermodynamic equilibrium. This approach allows us to write consistently the
path integral representation for the partition function of gauge theories in a
simple manner. Furthermore, we find the Dyson-Schwinger-Fradkin equations and
the Ward-Fradkin-Takahashi identities for the Podolsky theory. We also write
the most general form for the polarization tensor in thermodynamic equilibrium.

The partition function of a three-dimensional $\mathcal{N} =2$ theory on the
manifold $\mathcal{M}_{g,p}$, an $S^1$ bundle of degree $p$ over a closed
Riemann surface $\Sigma_g$, was recently computed via supersymmetric
localization. In this paper, we compute these partition functions at large $N$
in a class of quiver gauge theories with holographic M-theory duals. We provide
the supergravity bulk dual having as conformal boundary such three-dimensional
circle bundles. These configurations are solutions to $\mathcal{N}=2$ minimal
gauged supergravity and pertain to the class of Taub-NUT-AdS and Taub-Bolt-AdS
preserving $1/4$ of the supersymmetries. We discuss the conditions for the
uplift of these solutions to M-theory, and compute the on-shell action via
holographic renormalization. We show that the uplift condition and on-shell
action for the Bolt solutions are correctly reproduced by the large $N$ limit
of the partition function of the dual superconformal field theory. In
particular, the $\Sigma_g \times S^1 \cong \mathcal{M}_{g,0}$ partition
function, which was recently shown to match the entropy of $AdS_4$ black holes,
and the $S^3 \cong \mathcal{M}_{0,1}$ free energy, occur as special cases of
our formalism, and we comment on relations between them.

The partition function of a three-dimensional $\mathcal{N} =2$ theory on the manifold $\mathcal{M}_{g,p}$, an $S^1$ bundle of degree $p$ over a closed Riemann surface $\Sigma_g$, was recently computed via supersymmetric localization. In this paper, we compute these partition functions at large $N$ in a class of quiver gauge theories with holographic M-theory duals. We provide the supergravity bulk dual having as conformal boundary such three-dimensional circle bundles. These configurations are solutions to $\mathcal{N}=2$ minimal gauged supergravity and pertain to the class of Taub-NUT-AdS and Taub-Bolt-AdS preserving $1/4$ of the supersymmetries. We discuss the conditions for the uplift of these solutions to M-theory, and compute the on-shell action via holographic renormalization. We show that the uplift condition and on-shell action for the Bolt solutions are correctly reproduced by the large $N$ limit of the partition function of the dual superconformal field theory. In particular, the $\Sigma_g \times S^1 \cong \mathcal{M}_{g,0}$ partition function, which was recently shown to match the entropy of $AdS_4$ black holes, and the $S^3 \cong \mathcal{M}_{0,1}$ free energy, occur as special cases of our formalism, and we comment on relations between them.

Holographic model of a three-dimensional current carrying superconductor or
superfluid with {\it dark matter} sector described by the additional
$U(1)$-gauge field coupled to the ordinary Maxwell one, has been studied in the
probe limit. We investigated analytically by the Sturm-Liouville variational
method, the holographic s-wave and p-wave models in the background of the AdS
soliton as well as five-dimensional AdS black hole spacetimes. The two models
of p-wave superfluids were considered, the so called $SU(2)$ and the
Maxwell-vector. Special attention has been paid to the dependence of the
critical chemical potential and critical transition temperature on the velocity
of the condensate and {\it dark matter} parameters. The current $J$ in
holographic three-dimensional superconductor studied here, shows the linear
dependence on $T_c-T$ for both s and p-wave symmetry. This is in a significant
contrast with the previously obtained results for two-dimensional
superconductors, which reveal the $(T-T_c)^{3/2}$ temperature dependence. The
coupling constant $\alpha$, as well as, chemical potential $\mu_D$ and the
velocity $S_D$ of the {\it dark matter}, affect the critical chemical potential
of the p-wave holographic $SU(2)$ system. On the other hand, $\alpha$, {\it
dark matter} velocity $S_D$ and density $\rho_D$ determine the actual value of
the transition temperature of the same superconductor/superfluid set up.
However, the {\it dark matter} does not affect the value of the current.

A simple systematic method for calculating derivative expansions of the
one-loop effective action is presented. This method is based on using symbols
of operators and well known deformation quantization theory. To demonstrate its
advantages we present several examples of application for scalar theory,
Yang-Mills theory, and scalar electrodynamics. The superspace formulation of
the method is considered for K\"ahlerian and non-K\"ahlerian quantum
corrections for Wess-Zumino and for Heisenberg-Euler lagrangians in super QED
models.

We analyse the breakdown of supersymmetry in an ISS model in the presence of
gravity, under the requirement that the cosmological constant vanishes
dynamically. The gravitational backreaction is calculated in the metastable
minimum and, in conjuction with the condition V=0, this is shown to generate
non-zero F-terms for the squarks. Once the squarks are coupled to the messenger
sector, a gauge mediation scheme is realised and it leads to a distinctive soft
spectrum, with a two order of magnitude split between the gaugino and the soft
scalar masses.

The non-relativistic scattering of a spin-1/2 particle off a self-dual
monopole reduces, for large distances, to the dyon problem, studied previously
by D'Hoker and Vinet. The S matrix (calculated by Zwanziger's algebraic method
based on the o(3,1)\oplus o(3) dynamical symmetry, discovered by D'Hoker and
Vinet) is shown to factorize into the product of the spinless S-matrix, S_0,
with a spin-dependent factor. The total cross-section is identical to the one
found in the spinless case.

three dimensions. We find that both Maxwell-Chern-Simons and the Self-Dual
models admits the same fields redefinition. Maxwell-Proca action and its dual
also share this property. We show explicitly that a gauge-fixing term has no
influence on duality and fields redefinition.

We calculate corrections to the Bekenstein-Hawking entropy formula for the
five-dimensional topological AdS (TAdS)-black holes and topological de Sitter
(TdS) spaces due to thermal fluctuations. We can derive all thermal properties
of the TdS spaces from those of the TAdS black holes by replacing $k$ by $-k$.
Also we obtain the same correction to the Cardy-Verlinde formula for TAdS and
TdS cases including the cosmological horizon of the Schwarzschild-de Sitter
(SdS) black hole. Finally we discuss the AdS/CFT and dS/CFT correspondences and
their dynamic correspondences.

Localization properties of fields in compact extra dimensions are crucial
ingredients for string model building, particularly in the framework of
orbifold compactifications. Realistic models often require a slight deviation
from the orbifold point, that can be analyzed using field theoretic methods
considering (singlet) fields with nontrivial vacuum expectation values. Some of
these fields correspond to blow-up modes that represent the resolution of
orbifold singularities. Improving on previous analyses we give here an explicit
example of the blow-up of a model from the heterotic Mini-landscape. An exact
identification of the blow-up modes at various fixed points and fixed tori with
orbifold twisted fields is given. We match the massless spectra and identify
the blow-up modes as non-universal axions of compactified string theory. We
stress the important role of the Green-Schwarz anomaly polynomial for the
description of the resolution of orbifold singularities.

An exact identification of the blow-up modes at various fixed points and fixed tori with orbifold twisted fields is given. We match the massless spectra and identify the blow-up modes as non-universal axions of compactified string theory. We stress the important role of the Green-Schwarz anomaly polynomial for the description of the resolution of orbifold singularities.

The geodesic equation in the five-dimensional singly rotating black ring is
non-integrable unlike the case of the Myers-Perry black hole. In the Newtonian
limit of the black ring, its geodesic equation agrees with the equation of
motion of a particle in the Newtonian potential due to a homogeneous ring
gravitational source. In this paper, we show that the Newtonian equation of
motion allows the separation of variables in the spheroidal coordinates,
providing an non-trivial constant of motion quadratic in momenta. This shows
that the Newtonian limit of a black ring recovers the symmetry of its geodesic
system, and the geodesic chaos is caused by relativistic effects.

Toward getting finite results from N=4 SYM with alpha'-corrections

We take our first step toward getting finite results from the
alpha'-corrected D=4 N=4 SYM theory with emphasis on the field theory
techniques. Starting with the classical action of N=4 SYM with the leading
alpha'-corrections, we examine new divergence at one loop due to the presence
of the alpha'-terms. The new vertices do not introduce additional divergence to
the propagators or to the three-point correlators. However they do introduce
new divergence, e.g., to the scalar four-point function which should be
canceled by extra counter-terms. We expect that the counter-terms will appear
in the 1PI effective action that is obtained by considering the string annulus
diagram. We work out the structure of the divergence and comment on an
application to the anomalous dimension of the SYM operators in the context of
AdS/CFT.

We study N=2 supersymmetric U(1) gauge theory in non(anti)commutative N=2
harmonic superspace with the singlet deformation, which preserves chirality. We
construct a Lagrangian which is invariant under both the deformed gauge and
supersymmetry transformations. We find the field redefinition such that the N=2
vector multilplet transforms canonically under the deformed symmetries.

Non-Gaussian statistics of de Sitter spectators: A perturbative
derivation of stochastic dynamics

Scalar fields interacting with the primordial curvature perturbation during
inflation may communicate their statistics to the latter. This situation
motivates the study of how the probability density function (PDF) of a light
spectator field $\varphi$ in a pure de Sitter space-time, becomes non-Gaussian
under the influence of a scalar potential ${\mathcal V(\varphi)}$. One approach
to this problem is offered by the stochastic formalism introduced by
Starobinsky and Yokoyama. It results in a Fokker-Planck equation for the
time-dependent PDF $\rho (\varphi , t)$ describing the statistics of $\varphi$
which, in the limit of equilibrium gives one back the solution $\rho (\varphi)
\propto \exp \big[ - \frac{8 \pi^2}{3 H^4} {\mathcal V(\varphi)} \big]$. We
study the derivation of $\rho (\varphi , t)$ using quantum field theory tools.
Our approach yields an almost Gaussian distribution function, distorted by
minor corrections comprised of terms proportional to powers of $\Delta N \times
\mathcal O(\partial_\varphi) {\mathcal V(\varphi)}$, where $\Delta N$ is the
number of $e$-folds succeeding the Hubble-horizon crossing of $\varphi$'s
wavelengths, and $\mathcal O(\partial_\varphi)$ stands for a derivative
operator acting on ${\mathcal V(\varphi)}$. This general form is obtained
perturbatively and remains valid even with loop corrections. Our solution
satisfies a Fokker-Planck equation that receives corrections with respect to
the one found within the stochastic approach, allowing us to comment on the
validity of the standard equilibrium solution for generic potentials. We posit
that higher order corrections to the Fokker-Planck equation may become
important towards the equilibrium.

In this paper, we study the half-supersymmetric time-dependent configurations
in M-theory and their matrix models. We find a large class of 11D supergravity
solutions, which keeps sixteen supersymmetries. Furthermore, we investigate the
isometries of these configurations and show that in general these
configurations have no supernumerary supersymmetries. And also we define the
Matrix models in these backgrounds following Discrete Light-Cone Quantization
(DLCQ) prescription.

This is a shortened version of an invited talk at the XIII International
Workshop "Lie Theory and its Applications in Physics", June 17-23, Varna,
Bulgaria. A covariant canonical gauge theory of gravity free from torsion is
studied. Using a metric conjugate momentum and a connection conjugate momentum,
which takes the form of the Riemann tensor, a gauge theory of gravity is
formulated, with form-invariant Hamiltonian. By the metric conjugate momenta, a
correspondence between the Affine-Palatini formalism and the metric formalism
is established. For, when the dynamical gravitational Hamiltonian
$\tilde{H}_{Dyn}$ does not depend on the metric conjugate momenta, a metric
compatibility is obtained from the equation of motions, and the equations of
motion correspond to the solution is the metric formalism.

A supertube is a supersymmetric configuration in string theory which occurs
when a pair of branes spontaneously polarizes and generates a new dipole charge
extended along a closed curve. The dipole charge of a codimension-2 supertube
is characterized by the U-duality monodromy as one goes around the supertube.
For multiple codimension-2 supertubes, their monodromies do not commute in
general. In this paper, we construct a supersymmetric solution of
five-dimensional supergravity that describes two supertubes with such
non-Abelian monodromies, in a certain perturbative expansion. In supergravity,
the monodromies are realized as the multi-valuedness of the scalar fields,
while in higher dimensions they correspond to non-geometric duality twists of
the internal space. The supertubes in our solution carry NS5 and 5$_2^2$ dipole
charges and exhibit the same monodromy structure as the SU(2) Seiberg-Witten
geometry. The perturbative solution has $\mathrm{AdS}_2\times S^2$ asymptotics
and vanishing four-dimensional angular momentum. We argue that this solution
represents a microstate of four-dimensional black holes with a finite horizon
and that it provides a clue for the gravity realization of a pure-Higgs branch
state in the dual quiver quantum mechanics.

Given the path of a point particle, one can relate its acceleration and, in
general, its kinematics to the curvature scalars of its trajectory. Using this,
a general Ansatz is made for the Yang Mills connection corresponding to a
non-Abelian point source. The Yang Mills field equations are then solved
outside the position of the point source under physically reasonable

solutions contain the Trautman solution; moreover two of them are exact whereas
one of them is found using a series expansion in 1/R, where R is the retarded
distance. These solutions are new and, in their most general form, are not
gauge equivalent to the original Trautman solution.

Given the path of a point particle, one can relate its acceleration and, in general, its kinematics to the curvature scalars of its trajectory. Using this, a general Ansatz is made for the Yang Mills connection corresponding to a non-Abelian point source. The Yang Mills field equations are then solved outside the position of the point source under physically reasonable constraints such as finite total energy flux and finite total color charge. The solutions contain the Trautman solution; moreover two of them are exact whereas one of them is found using a series expansion in 1/R, where R is the retarded distance. These solutions are new and, in their most general form, are not gauge equivalent to the original Trautman solution.

Recently established connection between additive codes and Narain CFTs
provides a new tool to construct theories with special properties and solve
modular bootstrap constraints by reducing them to algebraic identities. We
generalize previous constructions to include many new theories, in particular
we show that all known optimal Narain theories, i.e. those maximizing the value
of spectral gap, can be constructed from codes. For asymptotically large
central charge $c$ we show there are code theories with the spectral gap
growing linearly with $c$, with the coefficient saturating the conjectural
upper bound. We therefore conjecture that optimal Narain theories for any value
of $c$ can be obtained from codes.

We use the string sigma model action in AdS_5 \times S^5 to reconstruct the
open string solution ending on the Wilson loop in S^3\times R parametrized by a
geometric angle in S^3 and an angle in flavor space. Under the interchange of
the world sheet space and time coordinates and the T-duality transformation
with the radial inversion, the static open string configuration associated with
the BPS Wilson loop with two equal angle parameters becomes a long open
spinning string configuration which is produced by taking the equal limit of
two frequencies for the folded spinning closed string with two spins in AdS_5
\times S^5.

I briefly review the present status of bosonic strings and discretized random
surfaces in D>1 which seem to be in a polymer rather than stringy phase. As an
explicit example of what happens, I consider the Kazakov-Migdal model with a
logarithmic potential which is exactly solvable for any D (at large D for an
arbitrary potential). I discuss also the meander problem and report some new
results on its representation via matrix models and the relation to the
Kazakov-Migdal model. A supersymmetric matrix model is especially useful for
describing the principal meanders.

We review cosmological solutions of type II superstrings and M-theory,
emphasizing the role of non-vanishing Ramond form backgrounds.
Compactifications on flat and, more generally, maximally symmetric spatial
subspaces are presented. We give a physical discussion of both inflating and
subluminally expanding cosmological solutions of such theories and explore
their singularity structure. An explicit example, in the context of the type
IIA superstring, is constructed. We then analyze compactifications of M-theory
on Ricci flat manifolds. The external part of U--duality and its relation to
cosmological solutions is studied in the low energy theory. In particular, we
investigate the behaviour of important cosmological properties, such as the
Hubble parameters and the transition time between two asymptotic regions, under
U-duality transformations. Motivated by Horava-Witten theory, we present an
explicit example of manifestly U-duality covariant M--theory cosmology in a
five-dimensional model resulting from compactification on a Calabi-Yau
three-fold.

We sketch briefly the essentials of the quantum groups and their application
to the dynamics of a q-deformed simple harmonic oscillator moving on a quantum
line, defined in the q-deformed cotangent (momentum phase) space. In this
endeavour, the quantum group $GL_{qp} (2)$- and the conventional rotational
invariances are respected together. During the course of this discussion, we
touch upon Rajaji's personality as a critical physicist and a bold and
adventurous man of mathematical physics.

We consider the D3-D7 model and use the spectral function of a probe fermion
on D7 to analyze the first order phase transition from the black-hole embedding
phase to another black-hole embedding phase in the presence of the finite
density and temperature. From the fermionic spectral functions, we study the
temperature dependence of the decay rate, and we observe various phenomena that
support the first order phase transition including jump in it at the critical
temperature that corresponds to the first order phase transition.

where N=1 supersymmetry is spontaneously broken at a low scale m_{3/2} by a
stringy Scherk-Schwarz mechanism. We review how the effective gauge couplings
at 1-loop may evade the "decompactification problem", namely the
proportionality of the gauge threshold corrections, with the large volume of

We study the effective transfer matrix within the semiclassical and
bifurcation phases of CDT quantum gravity. We find that for sufficiently large
lattice volumes the kinetic term of the effective transfer matrix has a
different sign in each of the two phases. We argue that this sign change can be
viewed as a Wick rotation of the metric. We discuss the likely microscopic
mechanism responsible for the bifurcation phase transition, and propose an
order parameter that can potentially be used to determine the precise location
and order of the transition. Using the effective transfer matrix we
approximately locate the position of the bifurcation transition in some region
of coupling constant space, allowing us to present an updated version of the
CDT phase diagram.

We show that the boundary states satisfy a nonlinear relation (the
idempotency equation) with respect to the star product of closed string field
theory. This relation is universal in the sense that various D-branes,
including the infinitesimally deformed ones, satisfy the same equation,
including the coefficient. This paper generalizes our analysis (hep-th/0306189)
in the following senses. (1) We present a background-independent formulation
based on conformal field theory. It illuminates the geometric nature of the
relation and allows us to more systematically analyze the variations around the
D-brane background. (2) We show that the Witten-type star product satisfies a
similar relation but with a more divergent coefficient. (3) We determine the
coefficient of the relation analytically. The result shows that the alpha
parameter can be formally factored out, and the relation becomes universal. We
present a conjecture on vacuum theory based on this computation.

(2) We show that the Witten-type star product satisfies a similar relation but with a more divergent coefficient. (3) We determine the coefficient of the relation analytically. The result shows that the alpha parameter can be formally factored out, and the relation becomes universal. We present a conjecture on vacuum theory based on this computation.

The first part of these lecture notes is mostly devoted to a comparative
discussion of the three basic large $N$ limits, which apply to fields which are
vectors, matrices, or tensors of rank three and higher. After a brief review of
some physical applications of large $N$ limits, we present a few solvable
examples in zero space-time dimension. Using models with fields in the
fundamental representation of $O(N)$, $O(N)^2$, or $O(N)^3$ symmetry, we
compare their combinatorial properties and highlight a competition between the
snail and melon diagrams. We exhibit the different methods used for solving the
vector, matrix, and tensor large $N$ limits. In the latter example we review
how the dominance of melonic diagrams follows when a special "tetrahedral"
interaction is introduced. The second part of the lectures is mostly about the
fermionic quantum mechanical tensor models, whose large $N$ limits are similar
to that in the Sachdev-Ye-Kitaev (SYK) model. The minimal Majorana model with
$O(N)^3$ symmetry and the tetrahedral Hamiltonian is reviewed in some detail;
it is the closest tensor counterpart of the SYK model. Also reviewed are
generalizations to complex fermionic tensors, including a model with
$SU(N)^2\times O(N)\times U(1)$ symmetry, which is a tensor counterpart of the
complex SYK model. The bosonic large $N$ tensor models, which are formally
tractable in continuous spacetime dimension, are reviewed briefly at the end.

The Riemann curvature correction to the type II supergravity at
eight-derivative level is given schematically as
$(t_8t_8+{1}{8}\eps_{10}\eps_{10})R^4$ at tree-level. The replacement of the
generalized Riemann curvature in $t_8t_8R^4$, proposed by Gross and Sloan,
produces various NS-NS couplings which are invariant under T-duality. Recently,
using the combination of S-duality and T-duality transformations on these
couplings, we have found groups of couplings which are invariant under the
S-duality transformation. In this paper, we have examined the couplings
involving the dilaton with direct scattering amplitude calculations of four
NS-NS vertex operators in the superstring theory and found exact agreement.
The coupling $\eps_{10}\eps_{10}R^4$ is a total derivative term at four-field
level. The $\sigma$-model beta function approach implies the presence of this
term at the tree-level. By examining the sphere-level scattering amplitude of
five gravitons, we have also confirmed the presence of this term in the
tree-level effective action.

The superconformal structure of coset superspaces with AdS_m x S^n geometry
of bosonic subspaces is studied. It is shown, in particular, that the
conventional superspace extensions of the coset manifolds AdS_2 x S^2, AdS_3 x
S^3 and AdS_5 x S^5, which arise as solutions of corresponding D=4,6, 10
supergravities and have been extensively studied in connection with AdS/CFT
correspondence, are not superconformally flat, though their bosonic
submanifolds are conformally flat. We give a group-theoretical reasoning for
this fact. We find that in the AdS_2 x S^2 and AdS_3 x S^3 cases there exist
different supercosets based on the supergroup OSp(4^*|2) which are
superconformally flat. We also argue that in D=2,3,4 and 5 there exist
superconformally flat `pure' AdS_D supercosets. Two methods of checking the
superconformal flatness are proposed. One of them consists in solving the
Maurer-Cartan structure equations and the other is based on embedding the
isometry supergroup of the AdS_m x S^n superspace into a superconformal group
in (m+n)-dimensional Minkowski space. Finally, we discuss some applications of
the above results to the description of supersymmetric dynamical systems.

We suggest that dark energy has a quantum informational origin. Landauer's
principle associated with the erasure of quantum information at a cosmic
horizon implies the non-zero vacuum energy having effective negative pressure.
Assuming the holographic principle, the minimum free energy condition, and the
Gibbons-Hawking temperature for the cosmic event horizon we obtain the
holographic dark energy with the parameter $d\simeq 1$, which is consistent
with the current observational data. It is also shown that both the
entanglement energy and the horizon energy can be related to Landauer's
principle.

In this work we use the deformation procedure and explore the route to obtain
distinct field theory models that present similar stability potentials.
Starting from systems that interact polynomially or hyperbolically, we use a
deformation function which allows to construct other theories having the
feature of giving rise to the same stability potentials. Such deformation
function leads to smooth potentials according to a specific choice of a single
parameter. Among the results, one shows that for models with asymmetric
topological sectors, the appearance of a new stability potential is also
possible.

Motivated by recent work we study rotating ellipsoidal membranes in the
framework of the light-cone supermembrane theory. We investigate stability
properties of these classical solutions which are important for the
quantization of super membranes. We find the stability modes for all sectors of
small multipole deformations. We exhibit an isomorphism of the linearized
membrane equation with that of the SU(N) matrix model for every value of $N$.
The boundaries of the linearized stability region are at a finite distance and
they appear for finite size perturbations.

Motivated by recent work we study rotating ellipsoidal membranes in the framework of the light-cone supermembrane theory. We investigate stability properties of these classical solutions which are important for the quantization of super membranes. We find the stability modes for all sectors of small multipole deformations. We exhibit an isomorphism of the linearized membrane equation with that of the SU(N) matrix model for every value of $N$. The boundaries of the linearized stability region are at a finite distance and they appear for finite size perturbations.

We show how causal relativistic Navier-Stokes equations arise from the
relativistic Boltzmann equation: the causality is preserved via a judicious
choice of the zero modes of the collision operator. A completely analogous
procedure may be used to extract causal hydrodynamics from the fluid-gravity
correspondence: again, causality of the hydrodynamic equations is preserved by
a suitable choice of zero modes of the corresponding differential operators in
the bulk. We give examples of zero modes which give rise to causal hydrodynamic
equations for non-conformal fluids with a conserved U(1) global symmetry
current.

The relation between celestial holography and Liouville field theory is
investigated. It is shown that duality relations between different Selberg type
integrals appearing in the Coulomb gas realization of Liouville correlation
functions induce a series of relations between celestial amplitudes with
shifted values of the operators dimensions $\Delta $.
This is a transcript of the talk delivered by the author at the Workshop on
Celestial Holography and Asymptotic Symmetries, Santiago de Chile, March 4-6,

There is a well known result from the Fierz-Pauli (FP) theory in de Sitter
background that is the existence of a lower bound for the mass $m$ of the spin
2 particle, the Higuchi bound. It establishes that $m^2\geq 2H^2$, where $H$ is
the Hubble parameter, in order to the theory presents no ghost-like
instabilities. In this sense, $m$ should be unacceptable high in order to
fulfill this condition at the time of the inflationary epoch of the Universe,
posing a difficulty to conciliate the FP theory with cosmology. In this letter
we show that the Higuchi bound can be circumvented in an alternative
description of massive spin-2 particles known as $\mathcal{L}(a_1)$ models. In
maximally symmetric spaces the theory has two free parameters which can be
consistently chosen in order to make the model absent of a lower bound for $m$.
Then, $m$ can be arbitrarily smaller than the energy scale of inflation
avoiding instabilities at that time.

The Hamiltonian of 2+1 dimensional Yang Mills theory was derived by Karabali,
Kim and Nair by using point splitting regularization. But in calculating e.g.
the vacuum wave functional this scheme was left in favour of arguments. Here we
follow up a conjecture of Leigh, Minic and Yelnikov of how this gap might be
filled by including all positive powers of the regularization parameter ($\ep
\to +0$). Admittedly, though we concentrate on the ground state in the large
$N$ limit, only two such powers could be included due to the increasing
complexity of the task.

We study higher order corrections to extremal black holes/black string in
five dimensions. These higher order corrections are due to supersymmetric
completion of R**2 term in five dimensions. By making use of the results we
extend the notion of very special geometry when higher derivative terms are
also taken into account. This can be used to make a connection between total
bundle space of near horizon wrapped M2's and wrapped M5's in the presence of
higher order corrections. We also show how the corrected geometry removes the
singularity of a small black hole.

Holography suggests a considerable reduction of degrees of freedom in
theories with gravity. However it seems to be difficult to understand how
holography could be realized in a closed re--contracting universe. In this
letter we claim that a scenario which achieves that goal will eliminate all
spatial degrees of freedom. This would require a different concept of quantum
mechanics and would imply an intriguing increase of power for the natural laws.

We construct the classical double copy formalism for M-theory. This extends
the current state of the art by including the three form potential of eleven
dimensional supergravity along with the metric. The key for this extension is
to construct a Kerr-Schild type Ansatz for exceptional field theory. This
Kerr-Schild Ansatz then allows us to find the solutions of charged objects such
as the membrane from a set of single copy fields. The exceptional field theory
formalism then automatically produces the IIB Kerr-Schild ansatz allowing the
construction of the single copy for the fields of IIB supergravity (with
manifest $SL(2)$ symmetry).

We calculate the low energy effective action of massless and massive complex
linear superfields coupled to a massive U(1) vector multiplet. Our calculations
include superspace higher derivative corrections and therefore go beyond
previous results. Among the superspace higher derivatives we find that terms
which lead to a deformation of the auxiliary field potential and may break
supersymmetry are also generated. We show that the supersymmetry breaking vacua
can only be trusted if there exists a hierarchy between the higher order terms.
A renormalization group analysis shows that generically a hierarchy is not
generated by the quantum corrections.

We construct generalizations of the Calogero-Sutherland-Moser system by
appropriately reducing a model involving many unitary matrices. The resulting
systems consist of particles on the circle with internal degrees of freedom,
coupled through modifications of the inverse-square potential. The coupling
involves SU(M) non-invariant (anti)ferromagnetic interactions of the internal
degrees of freedom. The systems are shown to be integrable and the spectrum and
wavefunctions of the quantum version are derived.

We construct a covariant generating function for the spectrum of chiral
primaries of symmetric orbifold conformal field theories with N=(4,4)
supersymmetry in two dimensions. For seed target spaces K3 and T4, the
generating functions capture the SO(21) and SO(5) representation theoretic
content of the chiral ring respectively. Via string dualities, we relate the
transformation properties of the chiral ring under these isometries of the
moduli space to the Lorentz covariance of perturbative string partition
functions in flat space.

We construct a covariant generating function for the spectrum of chiral primaries of symmetric orbifold conformal field theories with N=(4,4) supersymmetry in two dimensions. For seed target spaces K3 and T4, the generating functions capture the SO(21) and SO(5) representation theoretic content of the chiral ring respectively. Via string dualities, we relate the transformation properties of the chiral ring under these isometries of the moduli space to the Lorentz covariance of perturbative string partition functions in flat space.

We argue that four-dimensional black hole evaporation inevitably produces an
infinite number of soft particles in addition to the thermally distributed
`hard' Hawking quanta, and moreover that the soft and hard particles are highly
correlated. This raises the possibility that quantum purity is restored by
correlations between the hard and soft radiation, while inclusive measurements
which omit the soft radiation observe the thermal Hawking spectrum. In theories
whose only stable particle is the graviton, conservation laws are used to argue
that such correlations are in principle sufficient for the soft gravitons to
purify the hard thermal ones.

We explore the possibility that (Bose-Einstein) condensation of scalar fields
from string compactifications can lead to long-lived compact objects. Depending
on the type of scalar fields we find different realisations of star-like and
solitonic objects. We illustrate in the framework of type~IIB string
compactifications that closed string moduli can lead to heavy microscopic stars
with masses of order $\mathcal{V}^\alpha M_{\rm Planck}$, $\alpha=1,3/2,5/3$
where $\mathcal{V}$ is the volume of the extra dimensions. Macroscopic compact
objects from ultra-light string axions are realised with masses of order
$e^{\mathcal{V}^{2/3}}M_{\rm Planck}.$ Q-ball configurations can be obtained
from open string moduli whereas the closed string sector gives rise to a new
class of solutions, named PQ-balls, that arise in the two-field axion-modulus
system. The stability, the potential for the formation, and the observability
of moduli stars through gravitational waves are discussed. In particular we
point out that during the early matter phase given by moduli domination,
density perturbations grow by a factor $\mathcal{V}^{\beta}$ with $\beta>2$ and
non-linear effects cannot be neglected.

The monodromy relations in string theory provide a powerful and elegant
formalism to understand some of the deepest properties of tree-level field
theory amplitudes, like the color-kinematics duality. This duality has been
instrumental in tremendous progress on the computations of loop amplitudes in
quantum field theory, but a higher-loop generalisation of the monodromy
construction was lacking.
In this letter, we extend the monodromy relations to higher loops in open
string theory. Our construction, based on a contour deformation argument inside
open string diagrams, leads to new identities that relate planar and non-planar
topologies in string theory. We write one and two-loop monodromy formulae
explicitly at any multiplicity. In the field theory limit, at one-loop we
obtain identities that reproduce known results. At two loops, we check our
formulae by unitarity in the case of the four-point N=4 super-Yang-Mills
amplitude.

The constraints imposed on hydrodynamics by the structure of gauge and
gravitational anomalies are studied in two dimensions. By explicit integration
of the consistent gravitational anomaly, we derive the equilibrium partition
function at second derivative order. This partition function is then used to
compute the parity-violating part of the covariant energy-momentum tensor and
the transport coefficients.

We compute the braided groups and braided matrices $B(R)$ for the solution
$R$ of the Yang-Baxter equation associated to the quantum Heisenberg group. We
also show that a particular extension of the quantum Heisenberg group is dual
to the Heisenberg universal enveloping algebra $U_{q}(h)$, and use this result
to derive an action of $U_{q}(h)$ on the braided groups. We then demonstrate
the various covariance properties using the braided Heisenberg group as an
explicit example. In addition, the braided Heisenberg group is found to be
self-dual. Finally, we discuss a physical application to a system of n braided
harmonic oscillators. An isomorphism is found between the n-fold braided and
unbraided tensor products, and the usual `free' time evolution is shown to be
equivalent to an action of a primitive generator of $U_{q}(h)$ on the braided
tensor product.

The partition function and the order parameter for the chiral symmetry
breaking are computed for a family of 2-dimensional interacting theories
containing the gauged Thirring model. In particular we derive non-perturbative
expressions for the dependence of the chiral condensate on the temperature and
the curvature. Both, high temperature and high curvature supress the condensate
exponentially and we can associate an effective temperature to the curvature.

now answer it because of recent progress in solving the problem of zero modes
in the case of non-Abelian gauge theories. We also give a description of the

this recent solution to the problem of light-front zero modes.

four-point function in SU(N) gauge theories that arise solely from the
