Title: Decoupling and de Sitter Vacua in Approximate No-Scale Supergravities
Authors: M.C. David Marsh, Bert Vercnocke and Timm Wrase
Categories: hep-th
Comments: 30 pages
\\
  We study ${\cal N}=1$ supergravity with $N>1$ chiral superfields in which one
of the fields has a K\"ahler potential of exact no-scale type. Such systems
admit de Sitter (dS) solutions in which supersymmetry is predominantly broken
by the no-scale field, with only a small contribution to the breaking coming
from the other fields. Metastable dS vacua of this type were recently shown to
be achievable by the finetuning of an $N\times N$ sub-matrix of the Hessian
matrix at the critical point. We show that perturbatively small deformations of
the no-scale Minkowski vacuum into dS are only possible when the spectrum of
the no-scale vacuum, besides the no-scale field, contain an additional massless
mode. The no-scale structure allows for a decoupling of $N-2$ fields, and
metastability can be achieved by the tuning of ${\cal O}(N^0)$ parameters. We
illustrate this scenario in several examples, and derive a geometric condition
for its realisation in type IIB string theory. Supergravities in which the
complex structure moduli space is a symmetric space, such as the string theory
inspired STU-models, are non-generic and realise a modified version of the
scenario. For the STU-model with a single non-perturbative correction we
present an explicit analytic family of dS solutions that includes examples with
quantised fluxes satisfying the O3-plane tadpole condition.

Title: Bounds on intrinsic diffusivities in momentum dissipating holography
Authors: Andrea Amoretti, Alessandro Braggio, Nicodemo Magnoli, Daniele Musso
Categories: hep-th cond-mat.str-el
Comments: 5 pages, 1 figure
\\
  Systems not conserving the total momentum have both extrinsic,
momentum-dissipating and intrinsic, momentum-conserving interactions. Inspired
by a recently conjectured universal bound for thermo-electric diffusion
constants in critical incoherent strongly coupled systems and relying on
holographic analytical computations, we obtain bounds for the intrinsic
contributions to the diffusion constants in different holographic systems
featuring momentum dissipation. The model-independence of the intrinsic
contributions suggests a possible universal relevance of the results within,
and possibly beyond, the gauge/gravity context. We also study an incoherent
limit where the complete diffusion constants confirm the shape of the expected
bounds, although presenting non-universal coefficients.

Title: Topological anomalies for Seifert 3-manifolds
Authors: Camillo Imbimbo, Dario Rosa
Categories: hep-th
Comments: 31 pages
\\
  We study globally supersymmetric 3d gauge theories on curved manifolds by
describing the coupling of 3d topological gauge theories, with both Yang-Mills
and Chern-Simons terms in the action, to background topological gravity. In our
approach the Seifert condition for manifolds supporting global supersymmetry is
elegantly deduced from the topological gravity BRST transformations. A
cohomological characterization of the geometrical moduli which affect the
partition function is obtained. In the Seifert context Chern-Simons topological
(framing) anomaly is BRST trivial. We compute explicitly the corresponding
local Wess-Zumino functional. As an application, we obtain the dependence on
the Seifert moduli of the partition function of 3d supersymmetric gauge theory
on the squashed sphere by solving the anomalous topological Ward identities, in
a regularization independent way and without the need of evaluating any
functional determinant.

Title: Supersymmetry with non-geometric fluxes, or a \beta-twist in Generalized
  Geometry and Dirac operator
Authors: David Andriot, Andre Betz
Categories: hep-th math.DG
Comments: 25 pages + appendices and references
\\
  We study ten-dimensional supersymmetric vacua with NSNS non-geometric fluxes,
in the framework of \beta-supergravity. We first provide expressions for the
fermionic supersymmetry variations. Specifying a compactification ansatz to
four dimensions, we deduce internal Killing spinor equations. These
supersymmetry conditions are then reformulated in terms of pure spinors,
similarly to standard supergravity vacua admitting an SU(3)xSU(3) structure in
Generalized Complex Geometry. The standard d-H acting on the pure spinors is
traded for a generalized Dirac operator D, depending here on the non-geometric
fluxes. Rewriting it with an exponential of the bivector \beta leads us to
discuss the geometrical characterisation of the vacua in terms of a
\beta-twist, in analogy to the standard twist by the b-field. Thanks to D, we
also propose a general expression for the superpotential to be obtained from
standard supergravities or \beta-supergravity, and verify its agreement with
formulas of the literature. We finally comment on the Ramond-Ramond sector, and
discuss a possible relation to intermediate or dynamical SU(2) structure
solutions.

Title: New Scheme Transformations and Application to Study Scheme Dependence of
  an Infrared Zero of the Beta Function in Gauge Theories
Authors: Gongjun Choi and Robert Shrock
Categories: hep-th hep-ph
Comments: 13 pages, latex
Report-no: YITP-SB-2014-38
\\
  We present two new one-parameter families of scheme transformations and apply
these to study the scheme dependence of the infrared zero in the beta function
of an asymptotically free non-Abelian gauge theory up to four-loop order. Our
results provide a further quantitative measure of this scheme dependence,
showing that for moderate values of the gauge coupling and the parameter
specifying the scheme transformation, this dependence is relatively mild. We
also remark on a generalized multi-parameter family of rational scheme
transformations.

Title: Entropy from Scaling Symmetry Breaking
Authors: Neymar Cavalcante, Saulo Diles, Kumar S. Gupta and Amilcar R. de
  Queiroz
Categories: hep-th cond-mat.str-el quant-ph
Comments: 13 pages
\\
  The scaling symmetry in conformal quantum mechanics (CQM) can be broken due
to the boundary conditions that follow from the requirement of a unitary time
evolution of the Hamiltonian. We show that the scaling symmetry of CQM can be
restored by introducing a suitable mixed state, which is associated with a
nonvanishing von Neumann entropy. We give an explicit formula for the entropy
arising from the mixed state in CQM. Our work provides a direct link between
the restoration of a broken symmetry and von Neumann entropy.

  In this note, it is shown that closed string graviton scattering amplitudes

Title: Moduli in General $SU(3)$-Structure Heterotic Compactifications
Authors: Eirik Eik Svanes
Categories: hep-th hep-ph math.DG
Comments: 162 pages, 5 figures
\\
  In this thesis, we study moduli in compactifications of ten-dimensional
heterotic supergravity. We consider supersymmetric compactifications to
four-dimensional maximally symmetric space, commonly referred to as the
Strominger system. The compact part of space-time $X$ is a six-dimensional
manifold of what we refer to as a heterotic $SU(3)$-structure. We show that
this system can be put in terms of a holomorphic operator $\bar D$ on a bundle
$\mathcal{Q}=T^*X\oplus\mathrm{End}(TX)\oplus\mathrm{End}(V)\oplus TX$, defined
by a series of extensions. We proceed to compute the infinitesimal deformation
space of this structure, given by $T\mathcal{M}=H^{(0,1)}(\mathcal{Q})$, which
constitutes the infinitesimal spectrum of the four-dimensional theory. In doing
so, we find an over counting of moduli by $H^{(0,1)}(\mathrm{End}(TX))$, which
can be reinterpreted as $\mathcal{O}(\alpha')$ field redefinitions.
  We next consider non-maximally symmetric domain wall compactifications of the
form $M_{10}=M_3\times Y$, where $M_3$ is three-dimensional Minkowski space,
and $Y=\mathbb{R}\times X$ is a seven-dimensional non-compact manifold with a
$G_2$-structure. Here $X$ is a six dimensional compact space of half-flat
$SU(3)$-structure, non-trivially fibered over $\mathbb{R}$. By focusing on
coset compactifications, we show that the compact space $X$ can be endowed with
non-trivial torsion, which can be used in a combination with $\alpha'$-effects
to stabilise all geometric moduli. The domain wall can further be lifted to a
maximally symmetric AdS vacuum by inclusion of non-perturbative effects.
Finally, we consider domain wall compactifications where $X$ is a Calabi-Yau.
We show that by considering such compactifications, one can evade the usual
no-go theorems for flux in Calabi-Yau compactifications, allowing flux to be
used as a tool in such compactifications, even when $X$ is K\"ahler.

Title: Dynamical probe of thermodynamical properties in three-dimensional hairy
  AdS black holes
Authors: De-Cheng Zou, Yunqi Liu, Cheng-Yong Zhang and Bin Wang
Categories: hep-th gr-qc
Comments: 14 pages, 3 figures
\\
  We study the quasinormal modes (QNM) of electromagnetic perturbations for
rotating black hole with a nonminimally coupled scalar field hair and
Banados-Teitelboim-Zanelli (BTZ) in three-dimensional anti-de Sitter (AdS)
spacetimes. We find that the imaginary parts of quasinormal frequencies of
dynamical perturbations can reflect the properties of thermodynamical stability
disclosed by examining the free energy. In addition, we observe that the
imaginary part of QNM frequencies can also determine the dynamically preferred
stable configuration, which agrees with the study of the thermodynamically
stability. This dramatic relation between dynamics and thermodynamics is also
disclosed in three-dimensional static black hole backgrounds. The obtained
results further support that the QNM can be a dynamic probe of the
thermodynamic properties in black holes.

Title: Homogeneous Instantons in Bigravity

Categories: hep-th astro-ph.CO gr-qc
Comments: 19 pages, 2 figures, LaTeX
Report-no: YITP-14-83
\\
  We study homogeneous gravitational instantons, conventionally called the
Hawking-Moss (HM) instantons, in bigravity theory. The HM instantons describe
the amplitude of quantum tunneling from a false vacuum to the true vacuum.
Corrections to General Relativity (GR) are found in a closed form. Using the
result, we discuss the following two issues: reduction to the de
Rham-Gabadadze-Tolley (dRGT) massive gravity and the possibility of preference
for a large $e$-folding number in the context of the Hartle-Hawking (HH)
no-boundary proposal. In particular, concerning the dRGT limit, it is found
that the tunneling through the so-called self-accelerating branch is
exponentially suppressed relative to the normal branch, and the probability
becomes zero in the dRGT limit.

\\
  In this PhD thesis, we investigate a wide class of three-dimensional massive
gravity models and show how most of them (if not all) can be brought in a
first-order, Chern-Simons-like, formulation. This allows for a general analysis
of the Hamiltonian for this wide class of models. From the Chern-Simons-like
perspective, the known higher-derivative theories of 3D massive gravity, like
Topologically Massive Gravity and New Massive Gravity, can be extended to a
wider class of models. These models are shown to be free of (possibly
ghost-like) scalar excitations and exhibit improved behavior with respect to
Anti-de Sitter holography; the new models have regions in their parameter space
where positive boundary central charge is compatible with positive mass and
energy for the massive spin-2 mode. We discuss the construction of several of
these improved models in detail and derive the necessary constraints needed to
remove any unphysical degree of freedom. We also comment on the AdS/LCFT
correspondence which arises when the massive spin-2 mode becomes massless and
is replaced by a logarithmic mode. Most of the results have been published
elsewhere, however, a special effort is made here to present the aspects of
Chern-Simons-like theories in a pedagogical and comprehensive way.

Title: Minimal Log Gravity
Authors: Gaston Giribet, Yerko V\'asquez
Categories: hep-th
Comments: 13 pages
\\
  Minimal Massive Gravity (MMG) is an extension of three-dimensional
Topologically Massive Gravity that, when formulated about Anti-de Sitter space,
accomplishes to solve the tension between bulk and boundary unitarity that
other models in three dimensions suffer from. We study this theory at the
chiral point, i.e. at the point of the parameter space where one of the central
charges of the dual conformal field theory vanishes. We investigate the
non-linear regime of the theory, meaning that we study exact solutions to the
MMG field equations that are not Einstein manifolds. We exhibit a large class
of solutions of this type, which behave asymptotically in different manners. In
particular, we find analytic solutions that represent two-parameter
deformations of extremal Banados-Teitelboim-Zanelli (BTZ) black holes. These
geometries behave asymptotically as solutions of the so-called Log Gravity,
and, despite the weakened falling-off close to the boundary, they have finite
mass and finite angular momentum, which we compute. We also find time-dependent
deformations of BTZ that obey Brown-Henneaux asymptotic boundary conditions.
The existence of such solutions show that Birkhoff theorem does not hold in MMG
at the chiral point. Other peculiar features of the theory at the chiral point,
such as the degeneracy it exhibits in the decoupling limit of the Cotton
tensor, are discussed.

Title: Solutions to the problem of ELKO spinor localization in brane models
Authors: I. C. Jardim, G. Alencar, R. R. Landim, R. N. Costa Filho
Categories: hep-th
Comments: 7 pages
\\
  In this paper we present two different solutions to the problem of zero mode
localization of ELKO spinor. In a recent paper the present authors reopened
this problem since the solution presented before did not satisfy the boundary
condition at the origin. The first solution is given by the introduction of a
mass term and by coupling the spinor with the brane through a delta function.
The second solution is reached by a Yukawa geometrical coupling with the Ricci
scalar. This two models changes consistently the the boundary condition at
infinity and at the origin. For the case of Geometrical coupling we are able to
show that the zero mode is localized for any smooth version of the RS model.

field commutation relations that undermine the particle interpretation in the

Title: Entanglement entropy across a deformed sphere
Authors: M\'ark Mezei
Categories: hep-th cond-mat.str-el
Comments: 20 pages, 1 figure
\\
  I study the entanglement entropy (EE) across a deformed sphere in conformal
field theories (CFTs). I show that the sphere (locally) minimizes the universal
term in EE among all shapes. In arXiv:1407.7249 it was derived that the sphere
is a local extremum, by showing that the contribution linear in the deformation
parameter is absent. In this paper I demonstrate that the quadratic
contribution is positive and is controlled by the coefficient of the stress
tensor two point function, $C_T$. Such a minimization result contextualizes the
fruitful relation between the EE of a sphere and the number of degrees of
freedom in field theory. I work with CFTs with gravitational duals, where all
higher curvature couplings are turned on. These couplings parametrize conformal
structures in stress tensor $n$-point functions, hence I show the result for
infinitely many CFT examples.

  We reconsider general aspects of Galilean-invariant thermal field theory.
Using the proposal of our companion paper, we recast non-relativistic
hydrodynamics in a manifestly covariant way and couple it to a background
spacetime. We examine the concomitant consequences for the thermal partition
functions of Galilean theories on a time-independent, but weakly curved
background. We work out both the hydrodynamics and partition functions in
detail for the example of parity-violating normal fluids in two dimensions to
first order in the gradient expansion, finding results that differ from those
previously reported in the literature. As for relativistic field theories, the
equality-type constraints imposed by the existence of an entropy current appear
to be in one-to-one correspondence with those arising from the existence of a
hydrostatic partition function. Along the way, we obtain a number of useful
results about non-relativistic hydrodynamics, including a manifestly
boost-invariant presentation thereof, simplified Ward identities, the
systematics of redefinitions of the fluid variables, and the positivity of
entropy production.

Title: Gapped Domain Walls, Gapped Boundaries and Topological Degeneracy
Authors: Tian Lan, Juven Wang, Xiao-Gang Wen
Categories: cond-mat.str-el hep-th math.CT
Comments: 5+9 pages, 3 figures
\\
  Gapped domain walls, as topological line defects between topologically
ordered states in two spatial dimensions (2D), are examined. We provide simple
criteria to determine the existence of gapped domain walls, which apply to both
Abelian and non-Abelian topological orders. Our criteria also determine whether
the edge modes of a 2D topological order must be gapless, due to "global
gravitational anomalies". Furthermore, we introduce new mathematical objects,
the tunneling matrix $\mathcal{W}$ whose entries are the fusion-space
dimensions $\mathcal{W}_{ia}$, to label and completely classify different types
of gapped domain walls. Mathematically, we propose a classification of bimodule
categories between modular tensor categories. Since a gapped boundary is a
gapped domain wall between a bulk topological order and vacuum (regarded as a
trivial topological order), our result of gapped domain walls inclusively
contains that of gapped boundaries. In addition, we derive a topological ground
state degeneracy formula, on arbitrary orientable spatial 2-manifolds with
gapped domain walls, including closed 2-manifolds as well as open 2-manifolds
with gapped boundaries.

  We study reheating processes and its cosmological consequences in the
Starobinsky model embedded in the old-minimal supergravity. First, we consider
minimal coupling between the gravity and matter sectors in the higher curvature
theory, and transform it to the equivalent standard supergravity coupled to
additional matter superfields. We then discuss characteristic decay modes of
the inflaton and the reheating temperature $T_{\rm R}$. Considering a simple
model of supersymmetry breaking sector, we estimate gravitino abundance from
inflaton decay, and obtain limits on the masses of gravitino and supersymmetry
breaking field. We find $T_{\rm R}\simeq 1.0\times10^9$ GeV and the allowed
range of gravitino mass as $10^4$ GeV $\lesssim m_{3/2} \lesssim 10^5$ GeV,
assuming anomaly-induced decay into the gauge sector as the dominant decay
channel.

Title: Edge-entanglement spectrum correspondence in a non-chiral topological
  phase, and Kramers-Wannier duality
Authors: Wen Wei Ho, Lukasz Cincio, Heidar Moradi, Davide Gaiotto, Guifre Vidal
Categories: cond-mat.str-el hep-th quant-ph
\\
  In a system with chiral topological order, there is a remarkable
correspondence between the edge and entanglement spectra: the low energy
spectrum of the system in the presence of a physical edge coincides with the
lowest part of the entanglement spectrum (ES) across a virtual cut of the
system, up to rescaling and shifting. In this paper, we explore whether the
edge-ES correspondence extends to non-chiral topological phases. Specifically,
we consider the Wen-plaquette model which has Z_2 topological order. The
unperturbed model displays an exact correspondence: both the edge and
entanglement spectra within each topological sector a (a = 1,...,4) are flat
and equally degenerate. Here we show, through a detailed microscopic
calculation, that in the presence of generic local perturbations: (i) the
effective degrees of freedom for both the physical edge and the entanglement
cut consist of a spin-1/2 chain, with effective Hamiltonians H_edge^a and
H_ent.^a respectively, both of which have a Z_2 symmetry enforced by the bulk
topological order; (ii) there is in general no match between their low energy
spectra, that is, there is no edge-ES correspondence. However, if supplement
the Z_2 topological order with a global symmetry (translational invariance
along the edge/cut), i.e. by considering the Wen-plaquette model as a symmetry
enriched topological phase (SET), then there is a finite domain in Hamiltonian
space in which both H_edge^a and H_ent.^a realize the critical Ising model,
whose low energy effective theory is the c = 1/2 Ising CFT. This is achieved
because the presence of the global symmetry implies that both Hamiltonians, in
addition to being Z_2 symmetric, are Kramers-Wannier self-dual. Thus, the bulk
topological order and the global translational symmetry of the Wen-plaquette
model as a SET imply an edge-ES correspondence at least in some finite domain
in Hamiltonian space.

Title: Topological invariant quintessence
Authors: Mariafelicia De Laurentis
Categories: gr-qc astro-ph.GA hep-th
Comments: 8 pages
\\
  The issues of quintessence and cosmic acceleration can be discussed in the
framework of $F(R, {\cal G})$ theories of gravity where $R$ is the Ricci
curvature scalar and ${\cal G}$ is the Gauss-Bonnet topological invariant. It
is possible to show that such an approach exhausts all the curvature content
related to the Riemann tensor giving rise to a fully geometric approach to dark
energy.

Title: Inertial non-vacuum states viewed from the Rindler frame
Authors: Kinjalk Lochan, T. Padmanabhan
Categories: gr-qc hep-th
Comments: 25 pages, Comments welcome !
\\
  The appearance of the inertial vacuum state in Rindler frame has been
extensively studied in the literature, both from the point of view of QFT
developed using Rindler foliation and using the response of an Unruh-Dewitt
Detector (UDD). In comparison, less attention has been devoted to the study of
inertial non-vacuum states when viewed from the Rindler frame. We provide a
comprehensive study of this issue in this paper. We first present a general
formalism describing characterization of an arbitrary inertial state when
described using (i) an arbitrary foliation and (ii) the response of UDD moving
along an arbitrary trajectory. We use this formalism to explicitly compute the
results for the Rindler frame and uniformly accelerated detectors. Any
arbitrary inertial state will always have a thermal component in the Rindler
frame with additional contributions arising from the non-vacuum nature of the
inertial state. We classify the nature of the additional contributions in terms
of functions characterizing the inertial state. We establish that for all
physically well behaved normalizable inertial states, the correction terms
decay with the energy of the Rindler mode so that the high frequency limit is
dominated by the thermal noise. However, inertial states which are not strictly
normalizable, lead to a constant contribution at all high frequencies in the
Rindler frame. A similar behavior arises in the response of the UDD as well. In
the case of the detector response, we provide a physical interpretation for the
constant contribution at high frequencies in terms of total detection rate of
co-moving inertial detectors. We discuss two different approaches for defining
a transition rate for the UDD, when the two-point function lacks the time
translation invariance and discuss several features of different definitions of
transition rates. The implications are discussed.
