Abstract

We present a detailed study of the decoherence correction to surface-hopping that was recently derived from the exact factorization approach. Ab initio multiple spawning calculations that use the same initial conditions and same electronic structure method are used as a reference for three molecules: ethylene, methaniminium cation, and fulvene, for which non-adiabatic dynamics follows a photo-excitation. A comparison with the Granucci-Persico energy-based decoherence correction, and the augmented fewest-switches surface-hopping scheme shows that the three decoherence-corrected methods operate on individual trajectories in a qualitatively different way, but results averaged over trajectories are similar for these systems.
