Extended Data Fig. 4: Dynamical trajectories near the conical intersection.
From: Few-fs resolution of a photoactive protein traversing a conical intersection
Unless otherwise stated, arbitrary units. a, b, Time evolutions (chronos) of modes 2 and 3, respectively. c, The experimental dynamical trajectory (in black) obtained from modes 2 and 3 as collective variables x and y, respectively, and the best-fit simulated trajectory, with color showing the passage of time (see color bar). The red dot indicates the position of the conical intersection. d, The calculated de-excitation dynamics as reflected in the electronic state population for the trajectory shown in Panel c above. The brown and blue curves represent the populations of the upper and the lower adiabatic electronic states, respectively.
