Abstract:
Ultrafast spectroscopy provides a direct means to monitor real-time photochemical events in the femtosecond timescale. The key to understanding such experiments is to model the coupled electron-nuclear motion when the nuclear wavepacket passes through conical intersections - the region where two or more electronic states become degenerate. I will discuss our recent efforts in developing a novel local diabatic representation for the correlated electron–nuclear wave packet dynamics through conical intersections. This new framework captures all nonadiabatic effects, including electronic transitions, coherence, and geometric phases.
