The effects of long range electrostatic interaction in twisted bilayer graphene have been investigated using the Hartree-Fock approximation. The results demonstrate a significant dependence of band widths and shapes on electron filling, as well as the existence of broken symmetry phases at various densities.
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 sub-lattice symmetry, or both.
