Bulk-Boundary interaction and the second law in Hořava-Lifshitz cosmology
arXiv:1511.07580 · doi:10.1103/PhysRevD.92.123511
Abstract
By defining as a function which realizes the energy transference between the bulk and the boundary of spacetime, as we interprete it here in the framework of Hořava-Lifshitz (HL) cosmology, flat case, we discuss the validity of the second law of thermodynamics in the light of the sign changes of (changes in the direction of energy transference) and its consequences through the cosmic evolution, in particular, whether the thermal equilibrium between bulk and boundary is reached or not. Additionally, we discuss possible phase transitions experienced by the bulk and the boundary (seen as sign changes in their heat capacities) through the cosmic evolution. The energy density in the bulk is modeled under an holographic perspective. As far as we know, currently there is not observational data on bulk-boundary interaction.
