Our research interest is to optically access quantum materials with high sensitivity, and optically control their physical properties at ultrafast speed.

We use commerical Ti-Sapphire lasers and build our own terahertz and mid-infrared light sources to investigate quantum materials properties in and out of equilibrium. Recently we have been focusing on unconventional superconductors and mutiferroelectrics, the properties of which show a high sensitivity to their lattice structures. We use homebuilt pump-probe terahertz spectroscopy and second harmonic generation polarimetry to investigate novel phenomena emerged in the phonon driven state.
