A Lorentz-violating low-energy model for the bilayer Graphene
Y. M. P. Gomes, M. J. Neves
In this work, we propose a model with Lorentz symmetry violation which describes the electronic low energy limit of the AA-bilayer graphene (BLG) system. The AA-type bilayer is kno…

Tilted Dirac cone effects and chiral symmetry breaking in a planar four-fermion model
Y. M. P. Gomes, Rudnei O. Ramos
We analyze the chiral symmetry breaking in a planar four-fermion model with non-null chemical potential, temperature and including the effect of the tilt of the Dirac cone. The sys…
