Extremal Surface Barriers
Netta Engelhardt, Aron C. Wall
We present a generic condition for Lorentzian manifolds to have a barrier that limits the reach of boundary-anchored extremal surfaces of arbitrary dimension. We show that any surf…
Coarse-grained entropy and causal holographic information in AdS/CFT
William R. Kelly, Aron C. Wall
We propose bulk duals for certain coarse-grained entropies of boundary regions. The `one-point entropy' is defined in the conformal field theory by maximizing the entropy in a doma…
Generalized second law at linear order for actions that are functions of Lovelock densities
Sudipta Sarkar, Aron C. Wall
In this article we consider the second law of black holes (and other causal horizons) in theories where the gravitational action is an arbitrary function of the Lovelock densities.…
Unitarity of Maxwell theory on curved spacetimes in the covariant formalism
William Donnelly, Aron C. Wall
Quantum field theory in curved spacetime may be defined either through a manifestly unitary canonical approach or via the manifestly covariant path integral formalism. For gauge th…
