Figure 2. Exciton-collective mode states and free exciton dynamics.

Figure 2

(a) The energy levels of the exciton-collective mode states used to describe energy transfer Inline graphic. The red arrow denotes population transfer from Inline graphic to Inline graphic. (b) Quantum coherent dynamics of the PEB50 dimer in PE545 illustrating population of the lowest exciton ρYY(t) (thick blue curve) and the inter-exciton coherence in the ground-state of the collective mode |ρX0−Y0(t)| (thin red curve).
