1.Study and construct the structure of quantum states (We plan to design a new algorithm inspired by MERA(one particular tensor network) to study quantum state, which could also provide a good theoretical model to analyze a many-body problem by calculating geodesic in geometrical position) 2.Obtain maximally localized Wannier function by Lowdin orthogonalization （In this work, we use one traditional statistical algorithm: Principal component analysis(PCA)to handle the database of the trial function of old algorithm, we can obtain MLWF in some particular potential well condition conveying our new algorithm） I also do some research on time crystal in 2016 I have full interest in condensed matter physics by using brand new ways.
