Strongly correlated topological phases in moire materials

ORAL · Invited

Abstract

Moire materials offer a rich playground to realize strongly correlated topological phases. We discuss recent advances on correlation-driven topological phases in graphene and transition metal dichalcogenide moire heterostructures and conclude with an efficient algorithm to predict topological insulators in moire materials from the symmetry and quantum geometry of the constituent layers.
