Correlated Phases and Quantum Anomalous Hall Effects in Multilayer Graphene

Recent experiments on multilayer graphene materials have unearthed a zoo of phases, including correlated insulators, ferromagnetism, and quantum anomalous Hall states. In this work, we investigate the microscopic origin of these phases employing Hartree-Fock methods to understand the renormalized electronic bandstructure and the ground states that can be supported in rhombohedral stacked pentalayer graphene. Our findings highlight the fertile ground of two-dimensional materials as a platform for realizing correlated and quantum anomalous Hall phases of matter.
