Fig. presents the population dynamics for stronger electron-phonon couplings. We can see that the Spin Mapping method reproduces the exact result reasonably well up to t=5 a.u. At a longer time, however, this approach becomes less accurate compared to the exact results, missing the recurrence of the electronic Rabi oscillations. Nevertheless, as an independent trajectorybased approach, the Spin Mapping approach still outperforms both LSC-IVR and Ehrenfest for all model calculations presented here.
