Quantum dynamics from classical trajectories: New approaches to simulating biological and molecular photocatalysts

Abstract

We will describe new path-integral methods for the direct simulation of condensed-phase electron transfer, proton transfer, and proton-coupled electron transfer (PCET) reactions [1]. Specific topics will include (i) direct simulation PCET reaction mechanisms and rates in iron bi-imidazoline systems across multiple regimes [2,3] and (ii)recent progress in simulation of multi-electron processes.[1] Habershon S, Manolopoulos DE, Markland TE, and Miller TF, "Ring polymer mol. dynamics: Quantum effects in chem. dynamics from classical trajectories in an extended phase space," Annu.
