We are interested in
understanding and controlling intramolecular vibrational
energy redistribution - the primordial step
in a chemical reaction. We seek both time-dependent
and time-independent (eigenstates) insights using
classical, semiclassical
and quantum perspectives. The primary aim is to highlight the
classical-quantum correspondence of
energy flow dynamics in polyatomic molecules.
More specifically, we hope to elucidate
the phase space topology/transport in such systems which
typically show a mixed regular-chaotic phase space. Ultimately,
we would like to use our insights into classical dynamics to control
both classical and quantum dynamics. A brief introduction
to our research can be found
here and the writeup
gives a bit more detail.
