Figure reports some results on the 1 ps dynamics simulated based on CT-TSH (upper panels) and on TSH-ED (lower panels) for the isolated system in 2D (green lines) and for the same system coupled to the bath of 23 harmonic oscillators (purple lines). In the figure, the dynamics is analyzed by showing the behavior of the excited-state S 1 population (left panels) and the formation probability of the trans conformer (right panels) as functions of time. In addition, we are able to compare the trans probability with the corresponding results obtained in Ref. with the multi-configuration time-dependent Hartree method (MCTDH) and its multilayer generalization .
