Generalized Second Law of Thermodynamics in Quintom Dominated Universe

TL;DR

This paper examines whether the generalized second law of thermodynamics holds in a universe dominated by Quintom dark energy, analyzing different scenarios including quintessence, phantom, and their transition.

Contribution

It investigates the validity of the generalized second law in the Quintom dark energy model across various cosmic dominance scenarios.

Findings

The law holds in quintessence dominated universe

The law is valid during the transition phase

The law's validity in phantom dominated universe depends on specific conditions

Abstract

In this paper we will investigate the validity of the Generalized Second Law of thermodynamics for the Quintom model of dark energy. Reviewing briefly the quintom scenario of dark energy, we will study the conditions of validity of the generalized second law of thermodynamics in three cases: quintessence dominated, phantom dominated and transition from quintessence to phantom will be discussed.
