Thermodynamics of event horizon with modified Hawking temperature in scalar-tensor gravity

摘要: In recent past, Hawking temperature has been modified for the validity of thermodynamical laws at event horizon in general relativity context. This lead to introduction and it found that is more realistic on horizon. With this motivation, here we investigate consistency scalar-tensor gravity based models by examining generalized second law thermodynamics (GSLT) equilibrium (TE) order attain our goal, consider a spatially flat Friedman–Robertson–Walker Universe filled with ordinary matter boundary bounded thermal temperature. Next, calculate expressions GSLT TE using context action where there non-minimally coupling between scalar field Lagrangian (as chameleon field). From expression GSLT, find null energy condition must hold viable model dominated perfect fluid. Furthermore, better understand these complicated TE, explore two namely Brans–Dicke self-interacting potential Chameleon special cosmological solutions. Finally, some graphical representation have presented. analysis, power-law forms scale factor much favourable study universal as compared other choices analytic function.
