A recent experiment reported a large anomalous Hall effect in magic angle twisted bilayer graphene (TBG) aligned with a hexagonal boron nitride (h-BN) substrate at 3/4 filling of the conduction band. In this paper we study this system theoretically and propose explanations of this observation. We em...
