Emergent topological states have been found in partially filled Landau levels and Hofstadter bands; in both cases, a large magnetic field is required to engineer the underlying flat band. The recent observation of quantum anomalous Hall effects (QAH) in narrow band moir\\'e systems has led to the theoretical prediction that such phases may be realized even at zero magnetic field.
