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…
