First-order phase-transition on dynamical Lorentz symmetry breaking system
Y. M. P. Gomes, M. J. Neves
A model of 4-component massless fermions in a quartic self-interaction based on ref. \cite{gomes2022} is investigated in the presence of chemical potential and temperature via…

First order phase transitions within Weyl type of materials at low temperatures
Y. M. P. Gomes, Everlyn Martins, Marcus Benghi Pinto +1
We analyze the possible dynamical chiral symmetry breaking patterns taking place within Weyl type of materials. Here, these systems are modeled by the (2+1)-dimensional Gross-Neveu…

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…
