A new perspective for nonadiabatic dynamics with phase space mapping models

X He, J Liu - The Journal of Chemical Physics, 2019 - pubs.aip.org
Based on the recently developed unified theoretical framework [J. Liu, J. Chem. Phys. 145
(20), 204105 (2016)], we propose a new perspective for studying nonadiabatic dynamics
with classical mapping models (CMMs) of the coupled multistate Hamiltonian onto the
Cartesian phase space. CMMs treat the underlying electronic state degrees of freedom
classically with a simple physical population constraint while employing the linearized
semiclassical initial value representation to describe the nuclear degrees of freedom. We …
