de Sitter Thermodynamics: A glimpse into non equilibrium

TL;DR

This paper explores the thermodynamic evolution of Schwarzschild de Sitter space, demonstrating black hole evaporation, and extends these results to higher-dimensional Lovelock gravity theories with a positive cosmological constant.

Contribution

It provides a novel analysis of black hole thermodynamics in de Sitter space and extends the framework to higher-dimensional Lovelock gravity theories.

Findings

Black hole evaporation occurs in Schwarzschild de Sitter space.

Thermodynamical evolution is consistent with black hole evaporation.

Results are generalized to higher dimensions in Lovelock theories.

Abstract

In this article is shown that the thermodynamical evolution of a Schwarzschild de Sitter space is the evaporation of its black hole. The result is extended in higher dimensions to Lovelock theories of gravity with a single positive cosmological constant.
