Thermodynamics in $F(R)$ gravity with phantom crossing
arXiv:0901.1509 · doi:10.1016/j.physletb.2009.07.039
Abstract
We study thermodynamics of the apparent horizon in $F(R)$ gravity. In particular, we demonstrate that a $F(R)$ gravity model with realizing a crossing of the phantom divide can satisfy the second law of thermodynamics in the effective phantom phase as well as non-phantom one.
