Barrow's black hole entropy and the equipartition theorem
Everton M. C. Abreu, Jorge Ananias Neto, Edésio M. Barboza
The Barrow entropy appears from the fact that the black hole surface can be modified due to quantum gravitational outcome. The measure of this perturbation is given by a new expone…
On the equipartition theorem and black holes nongaussian entropies
Everton M. C. Abreu, Jorge Ananias Neto, Edésio M. Barboza +2
In this Letter we have shown that, from the standard thermodynamic functions, the mathematical form of an equipartition theorem may be related to the algebraic expression of a part…
Black holes quasinormal modes, Loop Quantum Gravity Immirzi parameter and nonextensive statistics
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
It is argued that, using the black hole area entropy law together with the Boltzmann-Gibbs statistical mechanics and the quasinormal modes of the black holes, it is possible to det…
Non-Gaussian thermostatistical considerations upon the Saha equation
Bráulio B. Soares, Edésio M. Barboza, Everton M. C. Abreu +1
The Saha equation provides the relation between two consecutive ionization state populations, like the Maxwell-Boltzmann velocity distribution of the atoms in a gas ensemble. Saha…
The unphysical character of dark energy fluids
Ronaldo C. Duarte, Edésio M. Barboza, Everton M. C. Abreu +1
It is well known that, in the context of general relativity, an unknown kind of matter that must violate the strong energy condition is required to explain the current accelerated…
Constraints on kinematic parameters at
C. Rodrigues Filho, Edésio M. Barboza
The standard cosmographic approach consists in performing a series expansion of a cosmological observable around and then using the data to constrain the cosmographic (or kin…
