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…
Probing the interference between non-linear, axionic and space-time-anisotropy effects in the QED vacuum
J. M. A. Paixão, L. P. R. Ospedal, M. J. Neves +1
We pursue the investigation of a generic non-linear extension of axionic electrodynamics in a Carroll-Field-Jackiw (CFJ) scenario that implements Lorentz-symmetry violation (LSV).…
Reconciling LSND and super-Kamiokande data through the dynamical Lorentz symmetry breaking in a four-Majorana fermion model
Y. M. P. Gomes, M. J. Neves
We propose a model of Majorana fermions with quartic self-couplings. These Majorana fermions acquire masses via a type II seesaw mechanism in which the physical eigenstates are ide…
Thermostatistical analysis for short-range interaction Potentials
M. J. Neves, Everton M. C. Abreu, Jorge B. de Oliveira +1
In this paper, we study the thermodynamics of short-range central potentials, namely, the Lee-Wick potential, and the Plasma potential. In the first part of the paper we obtain the…
A general relativity formulation for the Doplicher-Fredenhagen-Roberts noncommutative space-time
M. J. Neves, Everton M. C. Abreu
The Doplicher, Fredenhagen and Roberts (DFR) noncommutative (NC) formalism is propose in a curved space-time. In DFR approach, the NC parameter is promoted to the set of coordinate…
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…
