Entropic gravity from noncommutative black holes
Rafael C. Nunes, Hooman Moradpour, Edésio M. Barboza +2
In this paper we will investigate the effects of a noncommutative (NC) space-time on the dynamics of the universe. We will generalize the black hole entropy formula for a NC black…
Compressible Fluids with Maxwell-type equations, the minimal coupling with electromagnetic field and the Stefan-Boltzmann law
Albert C. R. Mendes, Flavio I. Takakura, Everton M. C. Abreu +1
In this work we have obtained a higher-derivative Lagrangian for a charged fluid coupled with the electromagnetic fluid and the Dirac's constraints analysis was discussed. A set of…
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…
Gauge-invariant extensions of the Proca model in a noncommutative space-time
Everton M. C. Abreu, Jorge A. Neto, Rafael L. Fernandes +1
The gauge invariance analysis of theories described in noncommutative (NC) space-times can lead us to interesting results since noncommutativity is one of the possible paths to inv…
A note on the relations between thermodynamics, energy definitions and Friedmann equations
H. Moradpour, Rafael C. Nunes, Everton M. C. Abreu +1
In what follows, we investigate the relation between the Friedmann and thermodynamic pressure equations, through solving the Friedmann and thermodynamic pressure equations simultan…
Jeans instability criterion from the viewpoint of non-gaussian statistics
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
In this Letter we have derived the Jeans length in the context of the Kaniadakis statistics. We have compared this result with the Jeans length obtained in the non-extensive Tsalli…
