Thermodynamic behavior of particular f(R,T)-gravity models

Nuclei, Particles, Fields, Gravitation, and Astrophysics

Abstract

We investigate the thermodynamics at the apparent horizon of the FRW universe in f(R, T) theory in the nonequilibrium description. The laws of thermodynamics are discussed for two particular models of the f(R, T) theory. The first law of thermodynamics is expressed in the form of the Clausius relation \(T_h d\hat S_h = \delta Q\), where δQ is the energy flux across the horizon and \(d\hat S\) is the entropy production term. Furthermore, the conditions for the generalized second law of thermodynamics to be preserved are established with the constraints of positive temperature and attractive gravity. We illustrate our results for some concrete models in this theory.
