Fig. presents the results of population dynamics in the three-state coupled Morse potential. Here, we present the Spin Mapping results only using focused initial conditions (solid lines). A time-step of 1 a.u., and 10 5 to 5 × 10 5 trajectories were used. The sampled initial conditions for spin mapping variables generates less accurate population as the initial nuclear force does not respect the physical occupancy of the electronic states. This has been extensively discussed in the recent work on trajectory-adjusted electronic zero point energy in classical Meyer-Miller vibronic dynamics. Nevertheless, the population dynamics of the Spin Mapping method with the focused initial conditions give almost exact results compared to the numerically exact calculations (dots), and outperform Ehrenfest dynamics (dashed lines). The Spin Mapping approach generates both accurate short time branching dynamics among three states as well as long time plateau value of the population, that is almost exact for models presented in panel (a) and (c). For the model presented in panel (b), the spin mapping formalism slightly outperforms the state-of-the-art γ-SQC approach, as well as the non-adiabatic ring polymer molecular dynamics approach.
