One-shot holography
Chris Akers, Adam Levine, Geoff Penington +1
Following the work of [2008.03319], we define a generally covariant max-entanglement wedge of a boundary region , which we conjecture to be the bulk region reconstructible from…
Large N algebras and generalized entropy
Venkatesa Chandrasekaran, Geoff Penington, Edward Witten
We construct a Type II von Neumann algebra that describes the large physics of single-trace operators in AdS/CFT in the microcanonical ensemble, where there is no need…
Finding Pythons in Unexpected Places
Netta Engelhardt, Geoff Penington, Arvin Shahbazi-Moghaddam
We argue that novel (highly nonclassical) quantum extremal surfaces play a crucial role in reconstructing the black hole interior even for isolated, single-sided, non-evaporating b…
A World without Pythons would be so Simple
Netta Engelhardt, Geoff Penington, Arvin Shahbazi-Moghaddam
We show that bulk operators lying between the outermost extremal surface and the asymptotic boundary admit a simple boundary reconstruction in the classical limit. This is the conv…
Holographic scattering requires a connected entanglement wedge
Alex May, Geoff Penington, Jonathan Sorce
In AdS/CFT, there can exist local 2-to-2 bulk scattering processes even when local scattering is not possible on the boundary; these have previously been studied in connection with…
Entanglement Wedge Reconstruction and the Information Paradox
Geoffrey Penington
When absorbing boundary conditions are used to evaporate a black hole in AdS/CFT, we show that there is a phase transition in the location of the quantum Ryu-Takayanagi surface, at…
Holographic Tensor Networks in Full AdS/CFT
Ning Bao, Geoffrey Penington, Jonathan Sorce +1
We present a general procedure for constructing tensor networks for geometric states in the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence. Given a state in a large…
Entanglement Wedge Reconstruction using the Petz Map
Chi-Fang Chen, Geoffrey Penington, Grant Salton
At the heart of recent progress in AdS/CFT is the question of subregion duality, or entanglement wedge reconstruction: which part(s) of the boundary CFT are dual to a given subregi…
Beyond Toy Models: Distilling Tensor Networks in Full AdS/CFT
Ning Bao, Geoffrey Penington, Jonathan Sorce +1
We present a general procedure for constructing tensor networks that accurately reproduce holographic states in conformal field theories (CFTs). Given a state in a large- CFT wi…
Learning the Alpha-bits of Black Holes
Patrick Hayden, Geoffrey Penington
When the bulk geometry in AdS/CFT contains a black hole, the boundary reconstruction of a given bulk operator will often necessarily depend on the choice of black hole microstate,…
