Traversable wormholes via a double trace deformation

- P. Gao, D. Jafferis, Aron C. Wall
- Physics
- 19 August 2016

A bstractAfter turning on an interaction that couples the two boundaries of an eternal BTZ black hole, we find a quantum matter stress tensor with negative average null energy, whose gravitational… Expand

Maximin Surfaces, and the Strong Subadditivity of the Covariant Holographic Entanglement Entropy

- Aron C. Wall
- Physics
- 15 November 2012

The covariant holographic entropy conjecture of AdS/CFT relates the entropy of a boundary region R to the area of an extremal surface in the bulk spacetime. This extremal surface can be obtained by a… Expand

Quantum extremal surfaces: holographic entanglement entropy beyond the classical regime

- N. Engelhardt, Aron C. Wall
- Physics
- 14 August 2014

A bstractWe propose that holographic entanglement entropy can be calculated at arbitrary orders in the bulk Planck constant using the concept of a “quantum extremal surface”: a surface which… Expand

Reconstruction of Bulk Operators within the Entanglement Wedge in Gauge-Gravity Duality.

- X. Dong, Daniel Harlow, Aron C. Wall
- Physics, Medicine
- Physical review letters
- 20 January 2016

In this Letter we prove a simple theorem in quantum information theory, which implies that bulk operators in the anti-de Sitter/conformal field theory (AdS/CFT) correspondence can be reconstructed as… Expand

Proof of the Quantum Null Energy Condition

- R. Bousso, Zachary Kenneth Fisher, Jason Koeller, Stefan Leichenauer, Aron C. Wall
- Physics
- 8 September 2015

We prove the quantum null energy condition (QNEC), a lower bound on the stress tensor in terms of the second variation in a null direction of the entropy of a region. The QNEC arose previously as a… Expand

Eternal Black Holes and Superselection in AdS/CFT

- D. Marolf, Aron C. Wall
- Physics
- 12 October 2012

It has been argued i) that Lorentz-signature solutions with wormholes connecting n asymptotically AdS regions describe bulk quantum states dual to n entangled but non-interacting CFTs and ii) that… Expand

Entanglement entropy of electromagnetic edge modes.

- William Donnelly, Aron C. Wall
- Physics, Medicine
- Physical review letters
- 5 December 2014

The vacuum entanglement entropy of Maxwell theory, when evaluated by standard methods, contains an unexpected term with no known statistical interpretation. We resolve this two-decades old puzzle by… Expand

Coarse graining holographic black holes

- N. Engelhardt, Aron C. Wall
- Physics
- 4 June 2018

A bstractWe expand our recent work on the outer entropy, a holographic coarse-grained entropy defined by maximizing the boundary entropy while fixing the classical bulk data outside some surface.… Expand

Decoding the Apparent Horizon: Coarse-Grained Holographic Entropy.

- N. Engelhardt, Aron C. Wall
- Physics, Medicine
- Physical review letters
- 7 June 2017

When a black hole forms from collapse in a holographic theory, the information in the black hole interior remains encoded in the boundary. We prove that the area of the black hole's apparent horizon… Expand

A proof of the generalized second law for rapidly changing fields and arbitrary horizon slices

- Aron C. Wall
- Physics
- 17 May 2011

The generalized second law is proven for semiclassical quantum fields falling across a causal horizon, minimally coupled to general relativity. The proof is much more general than previous proofs in… Expand
