Landau Analog Levels for Dipoles in the Noncommutative Space and Phase Space
L. R. Ribeiro, E. Passos, C. Furtado +1
In the present contribution we investigate the Landau analog energy quantization for neutral particles, that possesses a nonzero permanent magnetic and electric dipole moments, in…
The geometric phases in a background with Lorentz-symmetry violation
L. R. Ribeiro, E. Passos, C. Furtado +1
We analyze the nonrelativistic quantum dynamics of a single neutral spin half particle, with non-zero magnetic and electric dipole moments, moving in an external electromagnetic fi…
The ambiguity-free four-dimensional Lorentz-breaking Chern-Simons action
F. A. Brito, J. R. Nascimento, E. Passos +1
The four dimensional Lorentz-breaking finite and determined Chern-Simons like action is generated as a one loop perturbative correction via an appropriate Lorentz-breaking coupling…
Dynamical Lorentz and CPT symmetry breaking in a 4D four-fermion model
M. Gomes, T. Mariz, J. R. Nascimento +1
In a 4D chiral Thirring model we analyse the possibility that radiative corrections may produce spontaneous breaking of Lorentz and CPT symmetry. By studying the effective potentia…
Lorentz violation and the proper-time method
T. Mariz, J. R. Nascimento, A. Yu. Petrov +2
In this paper, we apply the proper-time method to generate the Lorentz-violating Chern-Simons terms in the four-dimensional Yang-Mills and non-linearized gravity theories. It is sh…
On the finiteness of the noncommutative supersymmetric Maxwell-Chern-Simons theory
A. F. Ferrari, M. Gomes, J. R. Nascimento +3
Within the superfield approach, we prove the absence of UV/IR mixing in the three-dimensional noncommutative supersymmetric Maxwell-Chern-Simons theory at any loop order and demons…
