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…
Forecast on lepton asymmetry from future CMB experiments
Alexander Bonilla, Rafael C. Nunes, Everton M. C. Abreu
We consider a cosmological lepton asymmetry in the form of neutrinos and impose new expected sensitivities on such asymmetry through the degeneracy parameter () by using some…
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…
Loop Quantum Gravity Immirzi parameter and the Kaniadakis statistics
Everton M. C. Abreu, Jorge Ananias Neto, Albert C. R. Mendes +1
In this letter we have shown that a possible connection between the LQG Immirzi parameter and the area of a punctured surface can emerge depending on the thermostatistics theory pr…
Tsallis' entropy, modified Newtonian accelerations and the Tully-Fisher relation
Everton M. C. Abreu, Jorge Ananias Neto, Albert C. R. Mendes +1
In this paper we have shown that the connection between the number of bits and the area of the holographic screen, where both were established in Verlinde's theory of entropic grav…
Classical electrodynamics and gauge symmetry of the X-boson
Mario J. Neves, Lucas Labre, Everton M. C. Abreu
In this paper we have obtained several new results concerning the X-boson, which is being considered recently as one of the main candidate of the dark matter particle content. The…
