Spontaneous Lorentz symmetry breaking and cosmological constant
T. Mariz, J. R. Nascimento, A. Yu. Petrov +2
This paper has been withdrawn by the authors due to need of essential revision.
On the ambiguities in the effective action in Lorentz-violating gravity
M. Gomes, T. Mariz, J. R. Nascimento +3
We investigate the occurrence of ambiguities for Lorentz-violating gravitational Chern-Simons term. It turns out that this term is accompanied by a coefficient depending on an unde…
On the noncommutative fields method in the three-dimensional Yang-Mills theory
J. R. Nascimento, A. Yu. Petrov, E. O. Silva
We apply the noncommutative fields method to the three-dimensional non-Abelian gauge theory. We find that, first, implementing the noncommutativity between the canonical momenta im…
On duality of the noncommutative Maxwell-Chern-Simons theory
M. Gomes, J. R. Nascimento, A. Yu. Petrov +2
We study the possibility of establishing the dual equivalence between the noncommutative Maxwell-Chern-Simons theory and the noncommutative self-dual theory. It turns to be that wh…
Lorentz symmetry violation and an Analog of Landau levels
E. Passos, L. R. Ribeiro, C Furtado +1
Within the context of Lorentz violating extended electrodynamics, we study an analog of Landau quantization for a system where a neutral particle moves in the presence of an electr…
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…
