The entropy of Hawking radiation and the generalized second law
Diego Pavón
We derive an approximate expression for the entropy of Hawking radiation filling a spherical box in stable thermodynamic equilibrium with the Schwarzschild black hole that produced…
Does the second law hold at cosmic scales?
Manuel Gonzalez-Espinoza, Diego Pavón
The second law of thermodynamics is known to hold at small scales also when gravity plays a leading role, as in the case of black holes and self-gravitating radiation spheres. It h…
Considerations on the thermal equilibrium between matter and the cosmic horizon
José Pedro Mimoso, Diego Pavón
A common feature in the thermodynamic analysis of homogeneous and isotropic world models is the assumption that the temperature of the fluids inside the cosmic horizon (including d…
Irreversible matter creation processes through a nonminimal curvature-matter coupling
Francisco S. N. Lobo, Tiberiu Harko, José P. Mimoso +1
An interesting cosmological history was proposed by Prigogine {\it et al.} who considered the Universe as a thermodynamically open system. This scenario is characterized by a proce…
Phantom behavior via cosmological creation of particles
Rafael C. Nunes, Diego Pavón
Recent determinations of the equation of state of dark energy hint that this may well be of the phantom type, i.e., . If confirmed by future experiments, this would st…
On detecting interactions in the dark sector with H(z) data
Pedro C. Ferreira, Diego Pavón, Joel C. Carvalho
An interesting approach to the cosmological coincidence problem is to allow dark matter and dark energy interact with each other also nongravitationally. We consider two general An…
