1.   Topological Physics  

Investigate topological quantum states under strong magnetic fields. By exploiting Landau quantization to reconstruct the electronic structure, achieve effective control of orbital and spin orders, and explore novel topological materials and quantum responses arising from Landau bands.

Representative work: Discovery of one-dimensional Weyl fermions; identification of three-dimensional van Hove singularities.

2.   Development of Magneto-Infrared Spectroscopy under High Magnetic Fields

Advance magneto-infrared spectroscopy techniques to address key challenges such as low sensitivity and limited spectral coverage under strong magnetic fields, enabling high-precision infrared measurements in extreme magnetic environments.

Representative work: Successful development of a high-precision, broadband, polarization-resolved magneto-infrared spectroscopy system.

3. Topological Infrared Devices

Explore novel infrared response mechanisms and establish new physical principles for infrared functional devices.

Representative work: Realization of 2D super-linear optoelectronic devices

4. Interdisciplinary Research

Leveraging advances in instrumentation, conduct cross-disciplinary studies in medicine, information science, and materials science using techniques such as infrared microscopy and high magnetic fields.

Representative work: Prediction of STILL rare disease based on infrared spectroscopy of a single human hair.
