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…
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…
Dispersion Relations in Noncommutative Theories
Tiago Mariz, J. R. Nascimento, Victor O. Rivelles
We present a detailed study of plane waves in noncommutative abelian gauge theories. The dispersion relation is deformed from its usual form whenever a constant background electrom…
