Dynamical Lorentz symmetry breaking in a 4D four-fermion model at finite temperature
M. Gomes, T. Mariz, J. R. Nascimento +3
In a 4D four-fermion model we study the dynamical restoration of Lorentz and CPT symmetries at finite temperature. We evaluate the gap equation both at zero and at finite temperatu…
Equivalence between supersymmetric self-dual and Maxwell-Chern-Simons models coupled to a matter spinor superfield
A. F. Ferrari, M. Gomes, A. C. Lehum +3
We study the duality of the supersymmetric self-dual and Maxwell-Chern-Simons theories coupled to a fermionic matter superfield, using a master action. This approach evades the dif…
Dynamical Lorentz symmetry breaking in 3D and charge fractionalization
B. Charneski, M. Gomes, T. Mariz +2
We analyze the breaking of Lorentz invariance in a 3D model of fermion fields self-coupled through four-fermion interactions. The low-energy limit of the theory contains various su…
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 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…
