He is mainly engaged in the study of electronic structure and ultrafart-resolved dynamics of quantum materials, and the experimental methods are angular resolved photoelectron spectroscopy (ARPES) and ultrafARt-time-resolved ARPES. It includes the following aspects:
1. Use ARPES of laboratory and synchrotron radiation sources to conduct research on electronic band structure of quantum materials such as superconducting, topological and low-dimensional materials, and deeply understand the microscopic mechanism of novel phenomena in materials.
2. Develop time-resolved ARPES based on extreme ultraviolet femtosecond light sources, carry out research on the non-equilibrium electronic structure during the interaction between laser and matter, and explore the optical regulation of materials.
