Linearised Second Law for Higher Curvature Gravity and Non-Minimally Coupled Vector Fields
Aron C. Wall, Zihan Yan
Expanding the work of arXiv:1504.08040, we show that black holes obey a second law for linear perturbations to bifurcate Killing horizons, in any covariant higher curvature gravity…
Violation of Unitarity in Gravitational Subregions
Aron C. Wall
This essay contends that in quantum gravity, some spatial regions do not admit a unitary Hilbert space. Because the gravitational path integral spontaneously breaks CPT symmetry, "…
A Survey of Black Hole Thermodynamics
Aron C. Wall
This is an introductory, up-to-date review of the essentials of black hole thermodynamics. The main topics surveyed are: (i) the four laws of thermodynamics as applied to a black h…
The holographic entropy increases in quadratic curvature gravity
Srijit Bhattacharjee, Sudipta Sarkar, Aron C. Wall
Standard methods for calculating the black hole entropy beyond general relativity are ambiguous when the horizon is non stationary. We fix these ambiguities in all quadratic curvat…
A Second Law for Higher Curvature Gravity
Aron C. Wall
The Second Law of black hole thermodynamics is shown to hold for arbitrarily complicated theories of higher curvature gravity, so long as we allow only linearized perturbations to…
A holographic proof of the averaged null energy condition
William R. Kelly, Aron C. Wall
The averaged null energy conditions (ANEC) states that, along a complete null curve, the negative energy fluctuations of a quantum field must be balanced by positive energy fluctua…
