Research Area & Interest
      My research area is theoretical condensed-matter physics, focusing on the theory about strongly-correlated electronic systems and superconductivity. The ultimate goal of my research is to find some fundamental law governing the structure of matter. One of my long term research area is the pairing mechanism of high temperature cuprate superconductivity, which is a mystery and great challenge of modern condensed-matter physics. A related area is quantum antiferromagnetism, particularly quantum spin liquid. This intriguing quantum state has attracted a lot of interest in the past several decades because it breaks Landau’s universal framework about phase and phase transition of matter and thus is of fundamental importance, but materials exhibiting genuine quantum spin liquid states have not yet been identified. Recently, I am also interested in other unconventional superconductors family including the Fe-based SC and the newly synthesized Cr-based SC, which share somewhat similar pairing mechanism with the cuprates superconductors. Another research area on my recent and future focus is topologically nontrivial quantum states. In the past several years, I was dedicated to predicting chiral and helical topological SC in real materials and model systems. Such efforts will be continued. I will also be interested in such many-body states as the topological-ordered states and the symmetry-protected topological phases.  I’m also interested in developing new numerical technics in the study of strongly-correlated systems, including the variational Monte-Carlo, the quantum Monte-Carlo, the density-matrix renormalization group and the tensor renormalization group.
