From magic angle twisted bilayer graphene to moiré superlattice quantum simulator

Abstract

Since the correlated insulating states and superconductivity in magic angle twisted bilayer graphene were discovered, the twisted moiré superlattice has attracted a wide range of research interest, and even has brought a new field, "twistronics", into being. In this review, we first give a history of experimentally discovering magic angle graphene and flat band, and then summarize the recent developments of twisted moiré superlattice, including twisted graphene systems and TMDCs, and finally introduce a notion of moiré superlattice quantum simulator.
