Efficient geometric integrators for nonadiabatic quantum dynamics. II. The diabatic representation

open access: yes, 2019
Exact nonadiabatic quantum evolution preserves many geometric properties of the molecular Hilbert space. In a companion paper [S. Choi and J. Van\'{\i}\v{c}ek, 2019], we presented numerical integrators of arbitrary-order of accuracy that preserve these ...
