Research Activities

Theoretical condensed matter physics is a very important area in physical sciences because not only it concerns with many fundamental subjects but also it has very wide and potentially important applications in material science, biophysical science, high technology, and even economy and finance, etc.  We have a very active research group in this field.  Our current research interest includes:

  1. strongly correlated electron systems;
  2. topological matters;
  3. quantum materials;
  4. quantum computing;
  5. quantum magnetism;
  6. spintronics and valleytronics;
  7. quantum transport;
  8. semiconductor optics;
  9. interdisciplinary study of cold atom physics and condensed matter physics
  10. computational approaches in quantum many-body systems
  11. scientific computing and neuromorphic AI accelerator in physics
