I am the postdoctoral fellow of Prof Ziyang Meng in the University of Hong Kong. I got my doctoral degree in Wuhan University under the guidance of Prof Yu Wang. For years, I have been interested in the numerical studies of the exotic physical states in optical lattice systems. With the development of experimental techniques, the twisted bilayer lattice has been realized in optical lattice experiment, and I am now interested in the interdisciplinary area of twistronics and optical lattice experiment. I am now studying how to design the quantum geometry-driven superfluid to Mott phase transition in both the bosonic and fermionic optical lattice systems.
