Cosmology and Non-additive Entropy

TL;DR

This paper investigates cosmological models derived from non-additive entropies, particularly those from superstatistics, to explore their implications for black hole thermodynamics and emergent gravity.

Contribution

It introduces cosmological models based on non-additive entropies from superstatistics, linking thermodynamics, black holes, and emergent gravity concepts.

Findings

Cosmologies from superstatistics entropies exhibit novel thermodynamic behaviors.

Non-additive entropies provide alternative frameworks for black hole thermodynamics.

Results suggest potential links between entropy formulations and emergent gravity theories.

Abstract

Non-additive entropies have been proposed as alternatives to understanding the thermodynamics of Black Holes. Moreover, it has been suggested that the difficulties of quantization of gravity are an indication that gravity is an emergent phenomenon, and therefore an entropic formulation is warranted. In this work, we explore cosmologies that come from non-additive entropies. We focus our study on the cosmologies derived from entropies in superstatistics.
