Quantum focusing conjecture
- R. Bousso, Zachary Kenneth Fisher, Stefan Leichenauer, and Aron C. Wall
- Physics
- 8 June 2015
We propose a universal inequality that unies the Bousso bound with the classical focussing theorem. Given a surface that need not lie on a horizon, we dene a nite generalized entropy Sgen as the area… 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
Disrupting Entanglement of Black Holes
- Stefan Leichenauer
- Physics
- 28 May 2014
We study entanglement in thermofield double states of strongly coupled conformal field theories by analyzing two-sided Reissner-Nordstrom solutions in anti–de Sitter space. The central object of… Expand
Consistent effective theory of long-wavelength cosmological perturbations
- S. Carroll, Stefan Leichenauer, Jason Pollack
- Physics
- 10 October 2013
Effective field theory provides a perturbative framework to study the evolution of cosmological large-scale structure. We investigate the underpinnings of this approach, and suggest new ways to… Expand
Holographic Proof of the Quantum Null Energy Condition
- Jason Koeller, Stefan Leichenauer
- Physics
- 18 December 2015
We use holography to prove the quantum null energy condition (QNEC) at leading order in large N for CFTs and relevant deformations of CFTs in Minkowski space which have Einstein gravity duals. Given… Expand

Null Geodesics, Local CFT Operators and AdS/CFT for Subregions
- R. Bousso, Ben Freivogel, Stefan Leichenauer, V. Rosenhaus, C. Zukowski
- Physics
- 20 September 2012
We investigate the nature of the AdS/CFT duality between a subregion of the bulk and its boundary. In global AdS/CFT in the classical G_N=0 limit, the duality reduces to a boundary value problem that… Expand
Entanglement Tsunami in (1+1)-Dimensions
- Stefan Leichenauer, M. Moosa
- Physics
- 15 May 2015
We study the time dependence of the entanglement entropy of disjoint in- tervals following a global quantum quench in (1+1)-dimensional CFTs at large-c with a sparse spectrum. The result agrees with… Expand
Geometric Constraints from Subregion Duality Beyond the Classical Regime
- C. Akers, Jason Koeller, Stefan Leichenauer, A. Levine
- Physics
- 27 October 2016
Subregion duality in AdS/CFT implies certain constraints on the geometry: entanglement wedges must contain causal wedges, and nested boundary regions must have nested entanglement wedges. We… Expand
The Quantum Focusing Conjecture Has Not Been Violated
- Stefan Leichenauer
- Physics
- 15 May 2017
Recent work of Fu, Koeller, and Marolf shows that in $d\geq 5$ dimensions a nonzero Gauss-Bonnet coupling of either sign can lead to a pointwise violation of the Quantum Focusing Conjecture. This… Expand
