Welcome! We are an experimental condensed matter physics research group at Tsinghua University. We use and develop advanced optical spectroscopies to investigate ultrafast phenomena and optical properties in novel materials. Experimental tools include pump-probe spectroscopy, transient grating spectroscopy, spin noise spectroscopy, photoluminescence, second-harmonic generation, and terahertz spectroscopy. Current fields of research include 2D materials, topological materials and magnetic thin films.
