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…
