In keeping with our theme of simplicity, integration of the TDQT approach with exact factorization, as a means of addressing the nonadiabatic regime, also appears to provide the "perfect marriage" of methodologies. In particular, the collection of multiple BOPES surfaces (and their couplings) that characterize the standard approach, is replaced with just a single TDPES (ignoring the TDVP for now)-that is treated in TDQT in exactly the same manner as a single-PES adiabatic calculation. This is key, because it appears to be extremely difficult to extend TDQT theory to multiple components. Conversely, within the exact factorization framework, TDQT appears to offer a much cleaner and more effective quantum trajectory methodology than do conventional wavefunction-based QTMs. In particular, the behavior of the TDQT trajectory ensemble evolution-even when computed from a numerically-determined, and thus noisy, TDPES-demonstrates its stability without introducing ad hoc smoothing procedures (as for example, in the form of viscosity forces also used by more traditional QTMs).
