Traversable wormholes via a double trace deformation
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
- 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
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.
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
- 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
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.
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
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.
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
- 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
