Massive Dirac fermions in moiré superlattices: A route towards topological flat minibands and correlated topological insulators

We demonstrate a generic mechanism to realize topological flat minibands by confining massive Dirac fermions in a periodic moiré potential, which can be achieved in a heterobilayer of transition metal dichalcogenides. We show that the topological phase can be protected by the symmetry of moiré poten...
