摘要(点击查看)While inventions like the optical microscope and X-ray diffraction have significantly enhanced our ability to uncover the nature, they mainly concentrate on obtaining steady-state information. However, the microcosm is a realm of dynamic evolution, with processes such as the vibrational motion of nuclei within molecules often occurring on the picosecond or femtosecond timescales, driven fundamentally by ultrafast electronic motions at the attosecond timescale. This talk will highlight the progress on the measurements and control of the light-induced ultrafast dynamics in molecules and polaritons. In particular, the ultrafast dynamics of cold molecules, e.g. the molecules in superfluid Helium nanodroplets and the bimolecular interactions, will be discussed. By developing a femtosecond angle-resolved spectroscopic imaging technique, we reveal the mechanisms of room-temperature polariton condensation in a microcavity and manipulates the fundamental process in condensation dynamics.
