TL;DR
This paper investigates the validity of the generalized second law of thermodynamics in a flat universe with interacting and non-interacting tachyonic, phantom, and scalar fields, finding it generally holds except in phantom-dominated cases.
Contribution
It analyzes the generalized second law in various field interactions, highlighting conditions under which it remains valid or breaks down.
Findings
Entropy derivative is negative and increases as redshift decreases in most cases.
The law does not hold in phantom field dominated universe.
Results depend on the type of scalar or tachyonic field involved.
Abstract
In the present work, we have considered tachyonic field, phantom field and scalar field in both interacting and non-interacting situations and investigated the validity of the generalized second law of thermodynamics in a flat FRW universe. We found that in all cases, excepting the phantom field dominated universe, the derivative of the entropy is remaining at negative level and is increasing with the decrease in the redshift.
