I mainly engaged in frontier research on quantum transport theory, quantum impurity models, nanoelectronics, molecular electronics, and orbital physics.

Current Research directions

1. Development and Application of Accurate Calculation Methods for Quantum Impurity Models. We have developed a set of non-perturbative density matrix cascade equations of motion for quantum open systems, which can solve nonequilibrium quantum many-body problems under different temperatures and correlation strengths. This calculation method is currently being used to accurately solve quantum multi-impurity models and has been applied to multi-quantum dot systems.

2. Many-Body Effects in Quantum Dots. Using non-perturbative density matrix cascade equations of motion, we systematically study many-body effects in single-, double-, and triple-quantum dots, including known phenomena such as the Kondo effect, many-body tunneling, spin gauge field effect, chiral spin states, topological Hall effect, and other potential new effects to be revealed.
