Probing the cosmological viability of non-gaussian statistics
Rafael C. Nunes, Edésio M. Barboza, Everton M. C. Abreu +1
Based on the relationship between thermodynamics and gravity we propose, with the aid of Verlinde's formalism, an alternative interpretation of the dynamical evolution of the Fried…
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…
Holographic considerations on non-gaussian statistics and gravothermal catastrophe
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
In this paper we have derived the equipartition law of energy using Tsallis formalism and the Kaniadakis power law statistics in order to obtain a modified gravitational constant.…
Thermodynamic aspects of dark energy fluids
Edésio M. Barboza, Rafael C. Nunes, Éverton M. C. Abreu +1
In this paper we have investigated the limits imposed by thermodynamics on a dark energy fluid. We have obtained the heat capacities and the compressibilities for a dark energy flu…
