Electrostatic interactions in twisted bilayer graphene
arXiv:2109.06038 · doi:10.1016/j.nanoms.2021.10.001
Abstract
The effects of the long range electrostatic interaction in twisted bilayer graphene are described using the Hartree-Fock approximation. The results show a significant dependence of the band widths and shapes on electron filling, and the existence of broken symmetry phases at many densities, either valley/spin polarized, with broken sublattice symmetry, or both.
