Multiscale confining dynamics from holographic RG flows

Daniel Elander, Anton F. Faedo, Carlos Hoyos +2

We consider renormalization group flows between conformal field theories in five (six) dimensions with a string (M-theory) dual. By compactifying on a circle (torus) with appropria…

State-Dependent Bulk-Boundary Maps and Black Hole Complementarity

Kyriakos Papadodimas, Suvrat Raju

We provide a simple and explicit construction of local bulk operators that describe the interior of a black hole in the AdS/CFT correspondence. The existence of these operators is…

The Black Hole Interior in AdS/CFT and the Information Paradox

Kyriakos Papadodimas, Suvrat Raju

We show that, within the AdS/CFT correspondence, recent formulations of the information paradox can be reduced to a question about the existence of certain kinds of operators in th…

Interpolating from Bianchi Attractors to Lifshitz and AdS Spacetimes

Shamit Kachru, Nilay Kundu, Arpan Saha +2

We construct classes of smooth metrics which interpolate from Bianchi attractor geometries of Types II, III, VI and IX in the IR to Lifshitz or $A d S_{2} \times S^{3}$ geometries in the…

A Note on Large N Thermal Free Energy in Supersymmetric Chern-Simons Vector Models

Shuichi Yokoyama

We compute the exact effective action for \cN=3 U(N)_k and \cN=4,6 U(N)_k\times U(N')_{-k} Chern-Simons theories with minimal matter content in the 't Hooft vector model limit unde…

Quantum Quench and Double Trace Couplings

Pallab Basu, Diptarka Das, Sumit R. Das +1

We consider quantum quench by a time dependent double trace coupling in a strongly coupled large N field theory which has a gravity dual via the AdS/CFT correspondence. The bulk th…

Superspace formulation and correlation functions of 3d superconformal field theories

Amin A. Nizami, Tarun Sharma, V. Umesh

We study $3 d$ SCFTs in the superspace formalism and discuss superfields and on-shell higher spin current multiplets in free $3 d$ SCFTs with $N = 1, 2, 3, 4$ and $6$ superconf…

Dynamical entanglement entropy with angular momentum and U(1) charge

Pawel Caputa, Gautam Mandal, Ritam Sinha

We consider time-dependent entanglement entropy (EE) for a 1+1 dimensional CFT in the presence of angular momentum and U(1) charge. The EE saturates, irrespective of the initial st…

Double Trace Flows and Holographic RG in dS/CFT correspondence

Diptarka Das, Sumit R. Das, Gautam Mandal

If there is a dS/CFT correspondence, time evolution in the bulk should translate to RG flows in the dual euclidean field theory. Consequently, although the dual field is expected t…

Cosmology or Catastrophe? A non-minimally coupled scalar in an inhomogeneous universe

Pawel Caputa, Sheikh Shajidul Haque, Joseph Olson +1

A non-minimally coupled scalar field can have, in principle, a negative effective Planck mass squared which depends on the scalar field. Surprisingly, an isotropic and homogeneous…

Chern Simons duality with a fundamental boson and fermion

Sachin Jain, Shiraz Minwalla, Shuichi Yokoyama

We compute the thermal free energy for all renormalizable Chern Simon theories coupled to a single fundamental bosonic and fermionic field in the 't Hooft large N limit. We use our…

Dissipative Nonlinear Dynamics in Holography

Pallab Basu, Archisman Ghosh

We look at the response of a nonlinearly coupled scalar field in an asymptotically AdS black brane geometry and find a behavior very similar to that of known dissipative nonlinear…

Confining Backgrounds and Quantum Chaos in Holography

Pallab Basu, Archisman Ghosh

Classical world-sheet string theory has recently been shown to be nonintegrable and chaotic in various confining string theory backgrounds -- the AdS soliton background in particul…

Duality and Higher Temperature Phases of Large $N$ Chern-Simons Matter Theories on $S^{2} \times S^{1}$

Tomohisa Takimi

It has been recently demonstrated that the thermal partition function of any large $N$ Chern-Simons gauge theories on $S^{2}$ , coupled to fundamental matter, reduces to a capped unit…

Quantum quench in matrix models: Dynamical phase transitions, Selective equilibration and the Generalized Gibbs Ensemble

Gautam Mandal, Takeshi Morita

Quantum quench dynamics is considered in a one dimensional unitary matrix model with a single trace potential. This model is integrable and has been studied in the context of non-c…

Extremal Horizons with Reduced Symmetry: Hyperscaling Violation, Stripes, and a Classification for the Homogeneous Case

Norihiro Iizuka, Shamit Kachru, Nilay Kundu +4

Classifying the zero-temperature ground states of quantum field theories with finite charge density is a very interesting problem. Via holography, this problem is mapped to the cla…

Phases of large $N$ vector Chern-Simons theories on $S^{2} \times S^{1}$

Sachin Jain, Shiraz Minwalla, Tarun Sharma +3

We study the thermal partition function of level $k$ U(N) Chern-Simons theories on $S^{2}$ interacting with matter in the fundamental representation. We work in the 't Hooft limit, $…
