报告简介：

Twisted bilayer graphene (TBG), or more generally, twistronics, is a hot topic in quantum physics. Intensive studies have been stimulated on the superconductivity, insulator transition and topological properties of TBG and related moiré systems. However, control of high degrees on the electronic systems is far from perfect. Owing to the excellent controllability of the system parameters and refined measurement techniques, optical lattices hosting ultracold atoms have become an ideal platform for simulating twistronics. By loading ultracold atoms into spin-dependent optical lattices, we have successfully realized the counterpart of TBG and observed exotic behaviors beyond TBG. In this talk, I will discuss our recent works on this topic.
