Echoes of chaos from string theory black holes
AbstractThe strongly coupled D1-D5 conformal field theory is a microscopic model of black holes which is expected to have chaotic dynamics. Here, we study the weak coupling limit of the theory where it...
View ArticleConformal Flow on S 3 and Weak Field Integrability in AdS 4
AbstractWe consider the conformally invariant cubic wave equation on the Einstein cylinder \({\mathbb{R} \times \mathbb{S}^3}\) for small rotationally symmetric initial data. This simple equation...
View ArticleHeavy-heavy-light-light correlators in Liouville theory
AbstractWe compute four-point functions of two heavy and two “perturbatively heavy” operators in the semiclassical limit of Liouville theory on the sphere. We obtain these “Heavy-Heavy-Light-Light”...
View ArticleMaximally rotating waves in AdS and on spheres
AbstractWe study the cubic wave equation in AdSd+1 (and a closely related cubic wave equation on S3) in a weakly nonlinear regime. Via time-averaging, these systems are accurately described by...
View ArticleFrom conformal blocks to path integrals in the Vaidya geometry
AbstractCorrelators in conformal field theory are naturally organized as a sum over conformal blocks. In holographic theories, this sum must reorganize into a path integral over bulk fields and...
View ArticleNon-local observables at finite temperature in AdS/CFT
AbstractWithin gauge/gravity duality, we consider the AdS-Schwarzschild metric in arbitrary dimensions. We obtain analytical closed-form results for the two-point function, Wilson loop and entanglement...
View ArticleConjecture on the butterfly velocity across a quantum phase transition
AbstractWe study an anisotropic holographic bottom-up model displaying a quantum phase transition (QPT) between a topologically trivial insulator and a non-trivial Weyl semimetal phase. We analyze the...
View ArticleHolographic pump probe spectroscopy
AbstractWe study the non-linear response of a 2+1 dimensional holographic model with weak momentum relaxation and finite charge density to an oscillatory electric field pump pulse. Following the time...
View ArticleA nonrelativistic limit for AdS perturbations
AbstractThe familiar c→ ∞ nonrelativistic limit converts the Klein-Gordon equation in Minkowski spacetime to the free Schrödinger equation, and the Einstein-massive-scalar system without a cosmological...
View ArticleEntanglement versus entwinement in symmetric product orbifolds
AbstractWe study the entanglement entropy of gauged internal degrees of freedom in a two dimensional symmetric product orbifold CFT, whose configurations consist of N strands sewn together into “long”...
View ArticleSuperluminal chaos after a quantum quench
AbstractThermal states holographically dual to black holes in Einstein gravity display maximal Lyapunov growth as well as “butterfly effect cones”. We study these effects in highly non-equilibrium...
View ArticleCaustics bounding entanglement wedges
AbstractWe study the caustics on the boundaries of entanglement wedges in the context of holography in asymptotically AdS3 spacetimes. These entanglement wedges play an important role in our...
View ArticleGeometric secret sharing in a model of Hawking radiation
AbstractWe consider a black hole in three dimensional AdS space entangled with an auxiliary radiation system. We model the microstates of the black hole in terms of a field theory living on an end of...
View ArticleSlow scrambling in extremal BTZ and microstate geometries
AbstractOut-of-time-order correlators (OTOCs) that capture maximally chaotic properties of a black hole are determined by scattering processes near the horizon. This prompts the question to what extent...
View ArticleTime-periodicities in holographic CFTs
AbstractDynamics in AdS spacetimes is characterized by various time-periodicities. The most obvious of these is the time-periodic evolution of linearized fields, whose normal frequencies form...
View ArticleSubmerging islands through thermalization
AbstractWe illustrate scenarios in which Hawking radiation collected in finite regions of a reservoir provides temporary access to the interior of black holes through transient entanglement “islands.”...

AbstractWe compute out-of-time-order correlators (OTOCs) in two-dimensional holographic conformal field theories (CFTs) with different left- and right-moving temperatures. Depending on whether the CFT...

AbstractWe study two-dimensional eternal black holes with non-zero mass, where each asymptotic boundary is in contact with a CFT on a circle, following the doubly holographic braneworld models...
View ArticleDelicate windows into evaporating black holes
AbstractWe revisit the model of an AdS2 black hole in JT gravity evaporating into an external bath. We study when, and how much, information about the black hole interior can be accessed through...
View ArticleDefinitions of entwinement
AbstractEntwinement was first introduced as the CFT dual to extremal, non-minimal geodesics of quotiented AdS3 spaces. It was heuristically meant to capture the entanglement of internal, gauged degrees...
