Evaporating Black Holes Coupled to a Thermal Bath
Hong Zhe Chen, Zachary Fisher, Juan Hernandez +2
We study the doubly holographic model of [arXiv:1908.10996] in the situation where a black hole in two-dimensional JT gravity theory is coupled to an auxiliary bath system at arbit…
Information Flow in Black Hole Evaporation
Hong Zhe Chen, Zachary Fisher, Juan Hernandez +2
Recently, new holographic models of black hole evaporation have given fresh insights into the information paradox [arXiv:1905.08255, arXiv:1905.08762, arXiv:1908.10996]. In these m…
A Semiclassical, Entropic Proof of a Weak Gravity Conjecture
Zachary Fisher, Christopher J. Mogni
We present a semiclassical proof of the weak gravity conjecture in spacetime dimensions for scalar matter gauged under a gauge group. We compute the non-perturbati…
Proof of the Quantum Null Energy Condition
Raphael Bousso, Zachary Fisher, Jason Koeller +2
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 aros…
A Quantum Focussing Conjecture
Raphael Bousso, Zachary Fisher, Stefan Leichenauer +1
We propose a universal inequality that unifies the Bousso bound with the classical focussing theorem. Given a surface that need not lie on a horizon, we define a finite general…
Entropy on a null surface for interacting quantum field theories and the Bousso bound
Raphael Bousso, Horacio Casini, Zachary Fisher +1
We study the vacuum-subtracted von Neumann entropy of a segment on a null plane. We argue that for interacting quantum field theories in more than two dimensions, this entropy has…
Proof of a Quantum Bousso Bound
Raphael Bousso, Horacio Casini, Zachary Fisher +1
We prove the generalized Covariant Entropy Bound, , for light-sheets with initial area and final area . The entropy is defined as a difference o…
