Generalized Second Law of Thermodynamics with Corrected Entropy in Tachyon Cosmology

TL;DR

This paper investigates the validity of the generalized second law of thermodynamics in tachyon cosmology, incorporating corrected entropy models and observational constraints to establish conditions for thermodynamic consistency.

Contribution

It introduces corrected entropy forms into tachyon cosmology and derives conditions under which the generalized second law holds, supported by observational data.

Findings

Conditions for GSL validity with corrected entropies are derived.

Logarithmic and power law entropy corrections are analyzed.

Model constraints are obtained from observational data.

Abstract

This work is to study the generalized second law (GSL) of thermodynamics in tachyon cosmology where the boundary of the universe is assumed to be enclosed by a dynamical apparent horizon. The model is constrained with the observational data. The two logarithmic and power law corrected entropy is also discussed and conditions to validate the GSL and corrected entropies are obtained.
