He, a theoretical quantum condensed matter physicist, is working in the area of strongly correlated systems. His present interest includes the fractional quantum Hall states in the second Landau level and some extoic non-Abelian quantum Hall states in the lowest Landau level, conventional BCS superconductors with disorder, and topological structures like skyrmions in ferromagnets, and ferroelectric systems. His group has been pioneered to predict an anomalous quantum Hall phase which they call as A-phase at much talked 5/2 quantum Hall state. His group has also prdicted the possibility of non-Abelian 2/5 quantum Hall state at the lowest Landau level. If it is experimentally proved, it will be an useful system for making fault-tolerant quantum computer.
