Fractional Chern insulator states in twisted bilayer graphene: An analytical approach
Recent experiments on bilayer graphene twisted near the magic angle have observed spontaneous integer quantum Hall states in the presence of an aligned hexagonal boron nitride substrate. These states arise from the complete filling of Chern bands. A natural question is whether fractional filling of...
