Research Interests:

My present research interest mainly focuses on exploring collective quantum (magnetic) states in strongly correlated many-body systems, including spin liquids, supersolid, spin transport, phase transition and critical phenomena, and other emergent phenomena. This direction has developed into a thriving field in recent decades in context of many important modern findings, such as the transition metal oxides and the artificial correlated systems induced by optical lattice.
