1/3 Fractional and Gapless Integer Quantum Anomalous Hall States in Rhombohedral Graphene

Jackson P. Butler, Tonghang Han, Andrew DiFabbio +6

The fractional quantum anomalous Hall (FQAH) effect occurs in moiré superlattices in both twisted bilayer MoTe${}_2$ and rhombohedral $n$-layer graphene aligned to hexagonal boron ni…
