Strong Correlation in Quantum Materials

My research is focused on finding and understanding exotic phenomena in the quantum materials. Especially, we study strongly correlated electron systems, where the entanglement of charge, spin and orbital degrees of freedom gives rise to a variety of emergent phenomena, for example, Mott insulators, various charge, spin and orbital orderings, metal–insulator transitions, multiferroics, superconductivity and so on.
