Abstract: Twisted moirè superlattice receives tremendous interests since the discovery of correlated insulating states and superconductivity in magic angle twist bilayer graphene (MA-TBG) [Nature 556 80 (2018), Nature 556 43 (2018)], even gives arise to a new field "twistronics" [Science 361 690 (2018)]. It is a new platform hosting strong electron correlations, providing an alternative for understanding unconventional superconductivity. In this article, we provide a review of recent experimental advances in the twisted moirè superlattice, from MA-TBG to twisted double bilayer graphene and other two-dimensional materials based moirè superlattice, covering correlated insulating states, superconductivity, magnetism, et al.

Key words: twisted 2D moirè, superlattice, electron correlations, superconductivity, magnetism
