Popis: | 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. Comment: Invited contribution to a special issue of Nano Materials Science. 12 pages, 8 figures. arXiv admin note: substantial text overlap with arXiv:2004.01577 |
