内容摘要：In crystalline solids, the interplay between topology and interactions can lead to various exotic topological correlated states, i.e., the recently discovered fractional Chern insulators (FCIs). Graphene based topological flat-bands provide a clean and highly tunable platform to investigate these states. In this talk, I will introduce our recent experiments on the observation of FCIs and other emergent correlated phenomena in rhombohedral hexalayer graphene (RHG)/hBN moiré superlattices. I will also talk about our recent results on the unconventional Chern insulators in magic angle bilayer graphene and twisted multilayer graphene systems.
