DESCRIPTION:Speakers: SON\, Dam Thanh ()\nDescription: The theory of the
fractional quantum Hall effect is based on the notion of the composite
fermion\, which is the low-energy quasiparticle for filling factor close
to 1/2. I will show that the particle-hole symmetry of the half-filled
Landau level implies that the composite fermion is a Dirac particle\,
characterized by a Berry phase of $pi$ around the Fermi surface. Physical
consequences are discussed.\nURL: https://agenda.infn.it/contributionDisp

DESCRIPTION:Speakers: PARNACHEV\, Andrei ()\nDescription: Topological
entanglement entropy\, a measure of the long-ranged entanglement\, is
related to the degeneracy of the ground state on a higher genus surface.
We construct a class of holographic models where such relation is similar
to the one exhibited by Chern-Simons theory in a certain large N limit.
Both the non-vanishing topological entanglement entropy and the ground
state degeneracy in these holographic models are consequences of the
topological Gauss-Bonnet term in the dual gravitational description.\nURL:

membrane located at a stretched horizon\, i.e. a very small distance
outside the horizon. In this talk I will show what are the limits of
validity of such approximation scheme. In particular I will argue that it
generically fails to capture massive quasinormal modes. I will also show
how it instead reproduces hydrodynamical modes of and AdS black brane as
long as an additional spurious excitation is removed from the

diffusion are essential handles to grasp the transport of strongly coupled
systems where momentum is quickly dissipated. Holography without momentum
conservation allows to compute the diffusion constants and explore the
formulation of (possibly general) bounds in analogy with the eta/s bound.
The talk focuses on the description of the diffusion constants computation
and properties highlighting the strength and limitations of the
associated conjectured bounds\, especially in view of attacking the

DESCRIPTION:Speakers: SEO\, Yunseok ()\nDescription: We study electric\,
thermoelectric\, and thermal conductivities of a strongly correlated
system in the presence of magnetic field by gauge/gravity duality. We
consider a general class of Einstein-Maxwell-Dilaton theory with axion
fields imposing momentum relaxation. Analytic general formulas for DC
conductivities and the Nernst signal are derived in terms of the black
hole horizon data. For an explicit model study we analyse in detail the
dyonic black hole modified by momentum relaxation. In this model\, the
Nernst signal shows a typical vortex-liquid effect when momentum
relaxation effect is comparable to chemical potential. We compute all AC
electric\, thermoelectric\, and thermal conductivities by numerical
analysis and confirms that their zero frequency limits precisely reproduce
our analytic formulas\, which is a non-trivial consistency check of our
methods. We discuss the momentum relaxation effect on conductivities
including cyclotron resonance poles.\nURL: https://agenda.infn.it/contribu

strongly-coupled conformal field theory with a holographic dual is coupled
to another theory that is weakly interacting. We show how semiholography
is set up in accordance with the Ward identities of the total theory. As
an example\, we charge fermions in the total theory under a U(1) gauge
field\, and compute the total electrical conductivity and Ward identity
corresponding to charge conservation. The resulting conductivity can be
expressed in vacuum CFT correlators which we compute in the dual
holographic spacetime. Most importantly one has to include the 3-point
vertex in the curved background for consistency.\nURL: https://agenda.infn

holographic model of the Kondo effect recently proposed by Erdmenger et.
al.\, i.e. of a magnetic impurity interacting with a strongly coupled
system. Specifically\, I focus on the challenges of computing
gravitational backreaction in this model\, which demands a study of the
Israel junction conditions. I present general results on these junction
conditions\, including analytical solutions for certain toy models\, that
may be relevant also more generally in the AdS/boundary CFT
correspondence. Furthermore\, similar junction conditions for a bulk
Chern-Simons field appearing in the holographic Kondo model are discussed.
I then focus on the computation and interpretation of entanglement
entropy in this holographic model.\nURL: https://agenda.infn.it/contributi

formulation of the local renormalization group equation is discussed.
This is framework in which the constraints of holomorphy and R-symmetry on
supersymmetric RG flows are manifest. Background fields are used to
define the super-Weyl symmetry off-criticality and to derive the
consistency conditions associated with this symmetry. An analog of the
"a-maximization" equation\, which is valid off-criticality is introduced.
This machinery is also applied to the study of conformal manifolds and a
simple proof is given that the metric on such manifolds is Kahler.\nURL: h

of these divergencies as arising from an infinite integration region for
a certain off-shell momentum. When one treats the theory purely on-shell\,
these divergencies must be seen (and regularized) in some other way. In
this talk I present an approach to tackle this problem\, in the particular
case of divergencies of scattering amplitudes\, using the so-called on-

local physics in a theory of quantum gravity is an important problem.
(A)dS/ CFT gives us a platform to study this issue from the CFT
perspective. The construction of local bulk scalars in semiclassical limit
of AdS/ CFT is well-known at order by order in 1/N perturbation. Here we
discuss the recent developments on this topic and in particular describe
how to extend this program for fields with spin- 1 and higher. We work in
both AdS and dS spaces. Local field construction is also made at arbitrary
cut-off surfaces in (A)dS and their prospective connections to
holographic RG are explored. Finally we argue about various finite N
scenarios and their effects on bulk locality and black hole information
paradox. Based on 1204.0126\, 1408.0415\, 1411.4657\, 1501.XXXXX and

DESCRIPTION:Speakers: GOUTERAUX\, Blaise ()\nDescription: What can
Gauge/Gravity duality teach us about Condensed Matter physics? While the
search goes on for gravitational duals to strange metals and other
strongly-coupled Condensed Matter systems\, I'll discuss two specific
examples where holographic computations have allowed us to formulate
effective theories of thermoelectric transport\, the existence of which
does not rely on holography or long-lived Landau quasiparticles. One is a
scaling theory of thermal quantum critical transport\, the other a theory
of 'hydrodynamics' without conserved momentum.\nURL: https://agenda.infn.i

light-hadron spectrum will be described from a superconformal
semiclassical approximation to light-front QCD and its embedding in AdS
space. This procedure uniquely determines the confinement potential for
arbitrary spin. To this end\, we will show that wave equations in AdS
space are dual to light-front supersymmetric quantum mechanical bound-
state equations in physical space-time. The specific breaking of
dilatation invariance within the supersymetric algebra explains hadronic
properties common to light mesons and baryons\, such as the observed mass
pattern in the radial and orbital excitations\, as well as their
distinctive and systematic features. Furthermore\, the generalized
supercharges connect the baryon and meson spectra. The lowest-lying
state\, the the pi-meson\, is massless in the chiral limit and has no
supersymmetric partner. Preliminary results extending the supersymmetric
relations across the heavy-light hadronic spectrum will also be
presented.\nURL: https://agenda.infn.it/contributionDisplay.py?contribId=4

Rosen bridge changes the topology of spacetime\, allowing (for example)
electric field lines to penetrate it. It has recently been suggested that
in the bulk of a theory of quantum gravity\, the quantum entanglement of
ordinary perturbative quanta should be viewed as creating a quantum
version of an Einstein-Rosen bridge between the quanta\, or a “quantum
wormhole”. For this “ER=EPR” correspondence to make sense it then
seems necessary for a quantum wormhole to allow (for example) electric
field lines to penetrate it. I will discuss (within low-energy effective
field theory) whether or not this happens.\nURL: https://agenda.infn.it/co

DESCRIPTION:Speakers: SCHALM\, Koenraad ()\nDescription: Holography has
provided a brand new window on the thermalization of Yang-Mills plasmas.
Compared to data from Relavistic Heavy Ion Collisions\, holographic
computations tend to (1) have a shorter thermalization time scale\, (2)
permit a linearized description in terms of quasinormal modes already at
extremely early stages rather than close to the final configuration\, (3)
thermalize less from the IR up than one would infer from weakly coupled
field theories. We will argue in particular that the holographic
linearized quasinormal description is an artefact of the large N limit\,
and that 1/N corrections should make the system more realistic. We test
this by introducing an additional decay of the quasinormal modes to each
other. Our results show that this diminishes the three discordances
between holographic thermalization and experiment.\nURL: https://agenda.in

charged operators are line operators\, surface operators\, etc.\, and
whose charged excitations are strings\, membranes\, etc. Many of the
properties of ordinary global symmetries apply here. They lead to Ward
identities and hence to selection rules on amplitudes. Such global
symmetries can be coupled to classical background fields and they can be
gauged by summing over these classical fields. These generalized global
symmetries can be spontaneously broken (either completely or to a
subgroup). They can also have ’t Hooft anomalies\, which prevent us from
gauging them\, but lead to ’t Hooft anomaly matching conditions. Such
anomalies can also lead to anomaly inflow on various defects and exotic
Symmetry Protected Topological phases. Our analysis of these symmetries
gives a new unified perspective of many known phenomena and uncovers new
results.\nURL: https://agenda.infn.it/contributionDisplay.py?contribId=9&s

DESCRIPTION:Speakers: FRANCHINI\, Fabio ()\nDescription: Matrix Models have
a strong history of success in describing a variety of situations\, from
nuclei spectra to conduction in mesoscopic systems\, from strongly
interacting systems to various aspects of mathematical physics\, from
holographic models to supersymmetric theories in the localization limit.
Traditionally\, the requirement of base invariance has lead to a
factorization of the eigenvalue and eigenvector distribution and\, in
turn\, to the conclusion that invariant models describe extended
systems.\nMoreover\, Wigner-Dyson statistics for the eigenvalues is a
hallmark of eigenvector delocalization. Thus\, in virtually all
applications of matrix models\, eigenvectors are discarded and one
considers just the eigenvalues. We show that deviations of the eigenvalue
statistics from the Wigner-Dyson universality reflects itself on the
eigenvector distribution and that a gap in the eigenvalue density breaks
the U(N) symmetry to a smaller one. Moreover\, this spontaneous symmetry
breaking means that egeinvectors become localized and that the system
looses ergodicity and that the system has lost replica symmetry
invariance.\nWe also consider models with log-normal weight\, such as
those emerging in Chern-Simons and ABJM theories. Their eigenvalue
distribution is intermediate between Wigner-Dyson and Poissonian\, which
candidates these models for describing a system intermediate between the
extended and localized phase. We show that they have a much richer energy
landscape than expected\, with their partition functions decomposable in a
large number of equilibrium configurations\, growing exponentially with
the matrix rank. We argue that this structure is a reflection of the non-
trivial (multi-fractal) eigenvector statistics.\nURL: https://agenda.infn.

theories with higher derivative corrections in AdS are dual to non-unitary
QFTs. In particular\, these may provide holographic examples of scale but
not conformally invariant field theories (SFT). A distinct signature of a
SFT is the non-vanishing scale anomaly R^2\, which may be computed
holographically. We perform a systematic near-boundary analysis of
relevant gravitational theories. Generically the R^2 anomaly is not
present. However we identify a very special class of theories (e.g. Chern-
Simons gravity in 5d) with non-standard near-boundary behaviour. For these
theories the R^2 anomaly may be present.\nURL: https://agenda.infn.it/con

the exact partition function of D-type N=4 quivers SCFTs on a three-
sphere coincides with the partition function of a gas of free fermions in
one dimension with a non-standard Hamiltonian. I will describe briefly the
mirror dual quiver theories and show that mirror symmetry is expressed as
a simple canonical transformation on the density operator of the quantum
mechanics. Finally I will discuss the exact evaluation of the perturbative
part of the free energy for these theories\, which takes the form an Airy

DESCRIPTION:Speakers: HARMARK\, Troels ()\nDescription: We introduce a new
type of quantum mechanical theory called Spin Matrix theory. It is a
generalization of nearest-neighbor spin chain theories. We show that Spin
Matrix theory arise from N=4 super Yang-Mills theory near certain zero-
temperature critical points. We find that Spin Matrix theory contains a
variety of phases that mimics that of the AdS/CFT correspondence\, and
hence gives a quantum mechanical model of the AdS/CFT correspondence.
Finally\, we suggest that Spin Matrix theory by itself can describe a
Holographic correspondence.\nURL: https://agenda.infn.it/contributionDispl

DESCRIPTION:Speakers: BERKOOZ\, Micha ()\nDescription: Field theories on
anti-de Sitter (AdS) space can be studied by realizing them as low-energy
limits of AdS vacua of string/M theory. In an appropriate limit\, the
field theories decouple from the rest of string/M theory. Since these
vacua are dual to conformal field theories\, this relates some of the
observables of these field theories on anti-de Sitter space to a subsector
of the dual conformal field theories. We exemplify this `rigid
holography' by studying in detail the six-dimensional ${\\cal N}=(2\,0)$
$A_{K-1}$ superconformal field theory (SCFT) on $AdS_5\\times
\\mathbb{S}^1$\, with equal radii for $AdS_5$ and for $\\mathbb{S}^1$. We
choose specific boundary conditions preserving sixteen supercharges that
arise when this theory is embedded into Type IIB string theory on
$AdS_5\\times \\mathbb{S}^5 / \\mathbb{Z}_K$. On
$\\mathbb{R}^{4\,1}\\times \\mathbb{S}^1$\, this six-dimensional theory
has a $5(K-1)$-dimensional moduli space\, with unbroken five-dimensional
$SU(K)$ gauge symmetry at (and only at) the origin. On $AdS_5\\times
\\mathbb{S}^1$\, the theory has a $2(K-1)$-dimensional `moduli space' of
supersymmetric configurations. We argue that in this case the $SU(K)$
gauge symmetry is unbroken everywhere in the `moduli space' and that this
five-dimensional gauge theory is coupled to a four-dimensional theory on
the boundary of $AdS_5$ whose coupling constants depend on the `moduli'.
This involves non-standard boundary conditions for the gauge fields on
$AdS_5$. Near the origin of the `moduli space'\, the theory on the
boundary contains a weakly coupled four-dimensional ${\\cal N}=2$
supersymmetric $SU(K)$ gauge theory. We show that this implies large
corrections to the metric on the `moduli space'. The embedding in string
theory implies that the six-dimensional ${\\cal N}=(2\,0)$ theory on
$AdS_5\\times \\mathbb{S}^1$ with sources on the boundary is a subsector
of the large $N$ limit of various four-dimensional ${\\cal N}=2$ quiver
SCFTs that remains non-trivial in the large $N$ limit. The same subsector
appears universally in many different four-dimensional ${\\cal N}=2$
SCFTs. We also discuss a decoupling limit that leads to ${\\cal
N}=(2\,0)$ `little string theories' on $AdS_5\\times \\mathbb{S}^1$.\nURL:

correspondence connects classes of Ricci-flat spacetimes to asymptotically
anti-de Sitter spacetimes\, and thus endows these vacuum gravity
solutions with a generalized conformal symmetry and a holographic
structure\, both inherited from AdS. The precise map requires however the
dimensional reduction over a round sphere\, and is therefore unsuitable to
gain insights into asymptotically flat spacetimes\, such as the
Schwarzschild black hole. In this talk\, I will explore the possibility of
circumventing this limitation and to extend the correspondence to more

the flavor fully backreacts to the glue. I will sketch the phase diagram

DESCRIPTION:Speakers: BRODSKY\, Stanley ()\nDescription: One of the most
fundamental problems in Quantum Chromodynamics is to understand the origin
of the mass scale which controls the range of color confinement and the
hadronic spectrum. We show that a mass gap and a fundamental color
confinement scale arise when one extends the formalism of de Alfaro\,
Fubini and Furlan to frame-independent light-front Hamiltonian theory.
Remarkably\, the resulting light-front potential has a unique form of a
harmonic oscillator in the light-front invariant impact variable if one
requires that the action remains conformally invariant. The result is a
single-variable relativistic equation of motion for qq¯ bound states\, a
"Light-Front Shr\\"odinger Equation"\, analogous to the nonrelativistic
radial Schr\\"odinger equation\, which incorporates color confinement and
other essential spectroscopic and dynamical features of hadron physics\,
including a massless pion for zero quark mass and linear Regge
trajectories with the same slope in the radial quantum number and orbital
angular momentum. The same equations with the correct hadron spin
dependence arise from the holographic mapping of modified AdS5 space with
a specific dilaton profile. A fundamental mass parameter ? appears\,
determining the hadron masses and the length scale which underlies hadron
structure. Quark masses can be introduced to account for the spectrum of
strange hadrons. This Light-Front Holographic approach predicts not only
hadron spectroscopy successfully\, but also hadronic form factors\, the
QCD running coupling at small virtuality\, and the light-front
wavefunctions of hadrons. Thus the combination of light-front dynamics\,
its holographic mapping to gravity in a higher-dimensional space and the
dAFF procedure provides new insight into the physics underlying color
confinement\, chiral invariance\, and the QCD mass scale.\nURL: https://ag

equilibration rates of strongly coupled quark-gluon plasmas in the absence
of conformal symmetry. We primarily consider a supersymmetric mass
deformation within N}=2^* gauge theory and use holography to compute
quasinormal modes of a variety of scalar operators\, as well as the
energy-momentum tensor. In each case\, the lowest quasinormal frequency\,
which provides an approximate upper bound on the thermalization time\, is
proportional to temperature\, up to a pre-factor with only a mild
temperature dependence. We find similar behaviour in other holographic
plasmas\, where the model contains an additional scale beyond the
temperature. Hence\, our study suggests that the thermalization time is
generically set by the temperature\, irrespective of any other scales\, in
strongly coupled gauge theories.\nURL: https://agenda.infn.it/contributio

heavy-ion collisions may be modeled as the collisions of black holes in
asymptotic anti-de-Sitter spacetimes. I will present results from the
evolution of spacetimes that describe the merger of asymptotically global
AdS black holes in 5D with an SO(3) symmetry. The initial trapped regions
are sourced by scalar field collapse and we are able to evolve through the
ensuing black hole merger as well as subsequent ring-down. The boundary
stress tensor corresponding to this evolution is found to correspond to
hydrodynamics at late times\, but not at early times. Implications and
generalizations of this work and signatures that could be relevant to
experimental observations at RHIC and the LHC will be discussed.\nURL: htt

whether arbitrarily small perturbations in global AdS space are
generically unstable and collapse into black holes on the time scale set
by gravi- tational interactions. We argue that current evidence\, combined
with our analysis\, strongly suggests that a set of nonzero measure in
the space of initial conditions does not collapse on this time scale. On
the other hand\, existing results do not provide an equally strong
indication whether the unstable solutions also form a set of nonzero mea-
sure. We perform an analysis in position space to address this puzzle\,
and our formalism allows us to directly address the vanishing-amplitude
limit. We show that gravitational self-interaction leads to tidal
deformations which are equally likely to focus or defocus energy\, and we
sketch the phase diagram accordingly. We also clarify the connection
between gravitational evolution in global AdS and holographic
thermalization.\nURL: https://agenda.infn.it/contributionDisplay.py?contri

is an external “dilaton” field introduced to match Weyl anomalies

DESCRIPTION:Speakers: TAYLOR\, Marika ()\nDescription: In this talk we will
discuss entanglement entropy for massive flavors\, from both holographic
and field theory perspectives. We will describe efficient computational
methods for the holographic entanglement entropy of brane systems\, and we
will show that the holographic entanglement entropy agrees precisely with
field theory expectations. We will explain how to extract finite terms in
the the entanglement entropy unambiguously and give physical
interpretations to these finite contributions. Finally we will discuss the
differential entropy for such systems\, arguing that (in contrast to
earlier work) the differential entropy does not capture global spacetime
structure.\nURL: https://agenda.infn.it/contributionDisplay.py?contribId=4

DESCRIPTION:Speakers: GRIGNANI\, Gianluca ()\nDescription: The possibility
of inter-layer exciton condensation in holographic models of a strongly
coupled double monolayer Dirac semi-metal are studied in detail. It is
showed that\, when the charge densities on the layers are exactly balanced
so that\, at weak coupling\, the Fermi surfaces of electrons in one
monolayer and holes in the other monolayer would be perfectly nested\,
inter-layer condensates can form for any separation of the layers. The
case where both monolayers are charge neutral is special. There\, the
inter-layer condensate occurs only for small separations and is replaced
by an intra-layer exciton condensate at larger separations. The phase
diagram for charge balanced monolayers for a range layer separations and
chemical potentials is found. We also show that\, in semi-metals with
multiple species of massless fermions\, the balance of charges required
for Fermi surface nesting can occur spontaneously by breaking some of the
internal symmetry of the monolayers. This could have important
consequences for experimental attempts to find inter-layer
condensates.\nURL: https://agenda.infn.it/contributionDisplay.py?contribId

DESCRIPTION:Speakers: DE BOER\, Jan ()\nDescription: Effective actions
based on scalar fields or Goldstone bosons are frequently used to describe
fluids. The precise interpretation of such actions from a gravitational
point of view has been somewhat unclear. In this talk I will describe a
holographic interpretation of such effective actions and discuss the
connection to other approaches to fluid/gravity duality.\nURL: https://age
