Seminar Title:
“NOVEL PATH-INTEGRAL BASED DYNAMICS FOR PHOTOCHEMISTRY”

Abstract:
The rational design of organic photovoltaics will require a clear understanding of the mechanism of photo- induced charge and energy transfer. In this talk, we describe a recently developed path-integral based method that employs classical molecular dynamics trajectories to simulate quantum dynamic effects in photochemical reactions [1, 2]. Further, we describe our work towards applying this new method to characterize the mechanism of nonadiabatic electronic state transitions for model systems that mimic exciton dynamics in organic photovoltaics.
