The Gödel solution in the modified gravity
C. Furtado, T. Mariz, J. R. Nascimento +2
We consider the modified gravity whose action represents itself as a sum of the usual Einstein-Hilbert action and the gravitational Chern-Simons term and show that the Gödel metric…
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…
Landau quantization for a neutral particle in presence of topological defects
K. Bakke, L. R. Ribeiro, C. Furtado +1
In this paper we study the Landau levels in the non-relativistic dynamics of a neutral particle which possesses a permanent magnetic dipole moment interacting with an external elec…
Gravitational Geometric Phase in the Presence of Torsion
Knut Bakke, Claudio Furtado, J. R. Nascimento
We investigate the relativistic and non-relativistic quantum dynamics of a neutral spin-1/2 particle submitted an external electromagnetic field in the presence of a cosmic disloca…
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…
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This paper has been withdrawn by the authors due to need of essential revision.
