Extended Data Fig. 2: 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 3 and 4, respectively. c, The experimental dynamical trajectory (in black) obtained from modes 3 and 4 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. For additional trajectories, see Supplementary Information. 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.
