Research Description: 

My research activities are mainly concentrated in two fields. One is to develop computational methods for the strongly correlated materials. The other one is to search for the topological non-trivial quantum state in realistic materials. In the first field, I developed the Gutzwiller density functional theory (LDA+Gutzwiller) with my collaborators and applied it to study many of the correlated materials, i.e. ferromagnetic metals, iron based superconductors and topological Kondo insulators. In the second field, together with my collaborators, I have proposed several very important topological insulators, i.e. Bi2Se3, Bi2Te3 and Sb2Te3. Later, we further predicted the quantum anomalous Hall effect in the magnetic topological insulator thin films, which has been observed in 2013. In 2015, my research team predicted the Wely semimetal materials TaAs family, which has soon been confirmed by both photo emission and transport experiments.
