Thermodynamic Implications of Multiquintessence Scenario

In this paper, we discuss the validity of the generalized second law of thermodynamics in the presence of a multi-component scalar field ([Formula: see text]) in a spatially flat Friedmann-Robertson-Walker (FRW) universe. We describe the first-order formalism by defining the Hubble parameter as [For...

description In this paper, we discuss the validity of the generalized second law of thermodynamics in the presence of a multi-component scalar field ([Formula: see text]) in a spatially flat Friedmann-Robertson-Walker (FRW) universe. We describe the first-order formalism by defining the Hubble parameter as [Formula: see text]. By using three super-potential models of the Hubble parameter, we analyze the validity of the generalized law and thermal equilibrium conditions in the presence of the logarithmically-corrected, Bekenstein-Hawking, Sharma-Mittal and [Formula: see text] entropies. It is noticed that the generalized law and thermal equilibrium conditions hold for some cases.
