Fig. 4. EET through the quantum mechanical motion of the nuclei.

(A) Population evolution within the 24-unit complex, analogous to Fig. 3A. Again, a representative set of pigment excitations in each ring are shown as solid lines. Dashed blue and green lines show the total populations of the two rings. The dashed cyan and lime lines show the total ring populations obtained from a classical treatment of the nuclei. (B) Enlarged view of the short time transients during excitation transfer. (C) Snapshots showing the spatial distribution of excitation energy as a function of time, analogous to Fig. 3C. Dynamical fluctuations arising from the quantum mechanical motion of the nuclei enable inward energy transfer.
