报告摘要：

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 original electronic systems is far from perfect. Recently the counterpart realization of TBG in cold atoms was reported[1]. In this system, two internal spin components are taken as the two synthetic layers, and distinctive lattice potentials are applied. When bosonic atoms are loaded, several different phases can be found. In this talk, I will discuss the physics in behind.
