Generalized second law of thermodynamics in presence of interacting DBI essence and other dark energies

TL;DR

This paper examines the validity of the generalized second law of thermodynamics when dark energy models interact with DBI-essence, finding that the law generally breaks down under these interactions despite the event horizon increasing over time.

Contribution

It investigates the impact of interactions between DBI-essence and various dark energy models on the validity of the generalized second law of thermodynamics.

Findings

GSL breaks down with interactions between dark energy and DBI-essence.

Event horizon continues to increase over time despite GSL violation.

Interactions affect thermodynamic laws in dark energy cosmology.

Abstract

In the present work we investigated the validity of the generalized second law (GSL) of thermo- dynamics in presence of interaction between DBI-essence and other four candidates of dark energy namely modified Chaplygin gas, hessence, tachyonic field and new agegraphic dark energy. It has been observed that the GSL breaks down in presence of the interactions. However, the event horizon remains to be an increasing function of time.
