Exciton band topology in spontaneous quantum anomalous Hall insulators: applications to twisted bilayer graphene

Exciton band topology in spontaneous quantum anomalous Hall insulators: applications to twisted bilayer graphene

We uncover topological features of neutral particle-hole pair excitations of correlated quantum anomalous Hall (QAH) insulators whose approximately flat conduction and valence bands have equal and opposite nonzero Chern number. Using an exactly solvable model we show that the underlying band topolog...
