: We present an explicit reconstruction of the interior of an AdS 2 black hole in Jackiw-Teitelboim gravity, that is entirely formulated in the dual SYK model and makes no direct reference to the gravitational bulk. We do this by introducing a probe “observer” in the right wormhole exterior and using the prescription of [arXiv:2009.04476] to transport SYK operators along the probe’s infalling worldline and into the black hole interior, using an appropriate SYK modular Hamiltonian. Our SYK…

Euclidean-to-Lorentzian wormhole transition and gravitational symmetry breaking in the Sachdev-Ye-Kitaev model
We study a two-site Sachdev-Ye-Kitaev (SYK) model with complex couplings and a weak inter-site interaction. At low temperatures, the system is dual to a Euclidean wormhole in Jackiw-Teitelboim (JT)…
Collisions of localized shocks and quantum circuits
We study collisions between localized shockwaves inside a black hole interior. We give a holographic boundary description of this process in terms of the overlap of two growing perturbations in a…
Going beyond ER=EPR in the SYK model
TLDR
It is suggested that a semiclassical wormhole corresponds to a certain class of such density matrices, and how they are constructed is suggested, and it is shown that this language allows for a finer criteria for when the wormhole is semiclassicals, which goes beyond entanglement.

Six-point functions and collisions in the black hole interior
Abstract In the eternal AdS black hole geometry, we consider two signals sent from the boundaries into the black hole interior shared between the two asymptotic regions. We compute three different…
Inside the hologram: reconstructing the bulk observer’s experience
Abstract We develop a holographic framework for describing the experience of bulk observers in AdS/CFT, that allows us to compute the proper time and energy distribution measured along any bulk…
Local bulk operators in AdS/CFT: A holographic description of the black hole interior
To gain insight into how bulk locality emerges from the holographic conformal field theory, we reformulate the bulk to boundary map in as local a way as possible. In previous work, we carried out…
Symmetries near the horizon
Abstract We consider a nearly-AdS2 gravity theory on the two-sided wormhole geometry. We construct three gauge-invariant operators in NAdS2 which move bulk matter relative to the dynamical…
Expanding the black hole interior: partially entangled thermal states in SYK
A bstractWe introduce a family of partially entangled thermal states in the SYK model that interpolates between the thermo-field double state and a pure (product) state. The states are prepared by a…
Probing typical black hole microstates
We investigate the possibility that the geometry dual to a typical AdS black hole microstate corresponds to the extended AdS-Schwarzschild geometry, including a region spacelike to the exterior. We…

Black holes and the butterfly effect
A bstractWe use holography to study sensitive dependence on initial conditions in strongly coupled field theories. Specifically, we mildly perturb a thermofield double state by adding a small number…
Diving into traversable wormholes
We study various aspects of wormholes that are made traversable by an interaction beween the two asymptotic boundaries. We concentrate on the case of nearly‐ AdS2 gravity and discuss a very simple…
