Thermostatistical analysis and negative heat capacities of Yukawa and Lee-Wick potentials in noncommutative phase spaces
Maria G. Sousa, Everton M. C. Abreu, Albert C. R. Mendes +1
In recent years, physical models based on noncommutative algebras have attracted considerable interest, as they provide a natural framework to incorporate a fundamental scale, ofte…
Noncommutative effects in Bianchi I cosmology with reduced relativistic gas
Thiago Moralles de Abreu, Gil de Oliveira Neto, Albert Carlo Rodrigues Mendes +1
In this work, we conduct a noncommutative analysis of a Bianchi I model coupled to a reduced relativistic gas. The classical field equations are modified by introducing noncommutat…
Revealing hidden symmetries and gauge invariance of the massive Carroll-Field-Jackiw model
Paulo R. F. Alves, Cleber N. Costa, Everton M. C. Abreu +2
In this paper we have analyzed the improved version of the Gauge Unfixing (GU) formalism of the massive Carroll-Field-Jackiw model, which breaks both the Lorentz and gauge invarian…
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…
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…
Hořava-Lifshitz cosmological models in noncommutative space-times
E. M. C. Abreu, A. C. R. Mendes, G. Oliveira-Neto +3
In this work, we will analyze a noncommutative (NC) version of the Friedmann-Robert-Walker cosmological models within the gravitational Hořava-Lifshitz theory. The matter content o…
