Research
I am interested in Strongly correlated electronic systems, High temperature superconductivity, Graphene, Magnetism, Computational Physics, Phase transitions, etc. More specifically, I study spin and charge orderings in cuprate superconductors, iron-based superconductors, nickelates and other layered perovskites. Using Quantum Monte Carlo methods and exact diagonalization, I investigate quantum phase transitions and critical phenomena. I also study noval quantum phase transitions which do not belong to conventional theories. Graphene and Frustrated spin systems are my favorite research fields too. During my MA+BA study, I worked on quantum solvable models, geometric phase, quantum optics, etc. Currently I am in Carlson group.
