We are interested in light-matter interaction in condensed matter physics, with an emphasis on novel physical phenomena emerging in nanoscale structures and at surfaces/interfaces. When electrons and phonons are confined in nanometer scale or at surface/interfaces, they respond differently to external stimuli. We investigate the unique nature and dynamics of such excited states using ultrafast laser spectroscopy. Our laser spectroscopy has sensitivity down to individual nanostructures, together with time resolution of femtoseconds and spectral coverage extending from far-infrared, visible to UV.
