报告题目:Light-induced ultrafast dynamics of molecules
and polaritons
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.
