Non-Equilibrium Fluctuations of Black Hole Horizons

TL;DR

This paper explores the non-equilibrium fluctuations of black hole horizons using statistical physics theorems, suggesting a microscopic violation of the second law to align with the Jarzynski equality.

Contribution

It applies fluctuation theorems and the Jarzynski equality to black hole horizons, providing a new perspective on their thermodynamic behavior.

Findings

Generalized second law derived from fluctuation theorems

Microscopic violations of the second law proposed

Connection between non-equilibrium physics and black hole thermodynamics

Abstract

We investigate non-equilibrium nature of fluctuations of black hole horizons by applying the fluctuation theorems and the Jarzynski equality developed in the non-equilibrium statistical physics. These theorems applied to space-times with black hole horizons lead to the generalized second law of thermodynamics. It is also suggested that the second law should be violated microscopically so as to satisfy the Jarzynski equality.
