Abstract

We derive the modified Friedmann equation corresponding to the power-law corrected entropy-area relation S A = A 4 h 1 − K α A 1− α 2 i which is motivated by the entan- glement of quantum fields in and out of the apparent horizon. We consider a non-flat modified FRW universe containing an interacting viscous dark energy with dark matter and radiation. For the selected model, we study the effect of the power-law correction term to the entropy on the dynamics of dark energy. Furthermore, we investigate the validity of the generalized second law (GSL) of gravitational thermodynamics on the apparent horizon and conclude that the GSL is satisfied for α < 2.
