Large Breakdowns of Entanglement Wedge Reconstruction
Chris Akers, Stefan Leichenauer, Adam Levine
We show that the bulk region reconstructable from a given boundary subregion --- which we term the reconstruction wedge --- can be much smaller than the entanglement wedge even whe…
Upper and Lower Bounds on the Integrated Null Energy in Gravity
Stefan Leichenauer, Adam Levine
We prove a lower bound on the integrated null energy along achronal geodesic segments using induced gravity on a brane in AdS/CFT. The bound follows from the assumption that bulk c…
QNEC-Preserving IR Regulators for the Entropy
Stefan Leichenauer
Recent work by Ishibashi, Maeda, and Mefford shows that the validity of the QNEC is sensitive to the IR regulator that one uses to define the entropy and its variations. In this no…
Energy is Entanglement
Stefan Leichenauer, Adam Levine, Arvin Shahbazi-Moghaddam
We compute the local second variation of the von Neumann entropy of a region in theories with a gravity dual. For null variations our formula says that the diagonal part of the Qua…
The Quantum Null Energy Condition, Entanglement Wedge Nesting, and Quantum Focusing
Chris Akers, Venkatesa Chandrasekaran, Stefan Leichenauer +2
We study the consequences of Entanglement Wedge Nesting for CFTs with holographic duals. The CFT is formulated on an arbitrary curved background, and we include the effects of curv…
The Quantum Focusing Conjecture Has Not Been Violated
Stefan Leichenauer
Recent work of Fu, Koeller, and Marolf shows that in dimensions a nonzero Gauss-Bonnet coupling of either sign can lead to a pointwise violation of the Quantum Focusing C…
