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…
Accelerated cosmos in a non-extensive setup
H. Moradpour, Alexander Bonilla, Everton M. C. Abreu +1
Here, we consider a flat FRW universe whose its horizon entropy meets the Rényi entropy of non-extensive systems. In our model, the ordinary energy-momentum conservation law is not…
The magnetocaloric effect from the point of view of Tsallis non-extensive thermostatistics
Isaías G. de Oliveira, Moisés A. S. M. Araújo, Everton M. C. Abreu +1
In this work we have analyzed the magnetocaloric effect (MCE) from the Tsallis thermostatistics formalism (TTF) point of view. The problem discussed here is a two level system MCE.…
Faddeev-Jackiw approach of the noncommutative spacetime Podolsky electromagnetic theory
Everton M. C. Abreu, Rafael L. Fernandes, Albert C. R. Mendes +1
The interest in higher derivatives field theories has its origin mainly in their influence concerning the renormalization properties of physical models and to remove ultraviolet di…
Faddeev-Jackiw analysis for the charged compressible fluid in a higher-derivative electromagnetic field background
Albert C. R. Mendes, Everton M. C. Abreu, Jorge Ananias Neto +1
In the present paper we will discuss the Faddeev-Jackiw symplectic approach in the analysis of a charged compressible fluid immersed in a higher-derivative electromagnetic field th…
Emergence of cosmic space, Gauss-Bonnet gravity, MOND theory and nonextensive considerations
Everton M. C. Abreu, Jorge Ananias Neto, Albert C. R. Mendes +1
In this paper, by using Verlinde's formalism and a modified Padmanabhan's prescription, we have obtained the lowest order quantum correction to the gravitational acceleration and M…
