Research Interests
My main research interests focus on the theoretical and numerical investigations of quantum many-body physics, such as quantum phase transition, quantum critical behavior and exotic topological states in strongly correlated fermionic systems and quantum magnetism, with help of the quantum Monte Carlo method, exact diagonalization and so on.
