In this work, we reported on a comparison between the coupled-trajectory schemes for nonadiabatic dynamics derived from the exact factorization and implemented in G-CTMQC, namely CTMQC, CTMQC-E and CTTSH, and the corresponding independent-trajectory methods Ehrenfest and surface hopping. We chose to perform the calculations on a molecular model for the photo-induced hydrogen dissociation process in phenol that despite its simplicity (analytical model with three electronic states and two nuclear coordinates) presents some fundamental challenges for the methods above, as we illustrated in the numerical studies reported here. The trajectory-based results have been benchmarked against exact results obtained based on the propagation of quantum vibronic wavepackets.
