Symmetry breaking states at commensurate fillings of the Moire bands of the twisted bilayer graphene

ORAL

Abstract

We study the twisted bilayer graphene system with the continuous model together with the long-range Coulomb interaction. Within the Hartree Fock approximation, we are able to find some symmetry breaking ground states at commensurate fillings of the Moire bands, which will gap out the Dirac points at the reduced Brillouin Zone that are otherwise protected by the symmetry.
