Research paperTheoreticalComputational MultiscaleFractional quantum anomalous Hall effects in rhombohedral multilayer graphene in the moir´eless limitBoran Zhou, Hui Yang, Ya-Hui ZhangarXiv·2024·10.48550/arXiv.2311.04217·arXiv:2311.04217AbstractThe paper studies fractional quantum anomalous Hall effects in rhombohedral multilayer graphene aligned with hBN in the limit where the moiré potential is a weak perturbation. Using Hartree-Fock and exact diagonalization, the authors argue that interaction-driven C=1 Chern insulators and fractional quantum anomalous Hall phases can arise even without an external moiré potential, interpreted as a spontaneous QAH crystal pinned by a small moiré perturbation. They analyze 4-, 5-, 6-, and 7-layer graphene systems and propose tuning of an interaction-generated moiré potential from a control layer.Read more
