which quantifies the exciton flux between molecules m and n. In this expression, the sign of F mn specifies the direction of the coherent exciton transfer, with F mn > 0 indicating transfer from m to n. The exciton flux is normalized by scaling each value to its maximum magnitude, F mn , and calculated for the dimer as a function of θ for both RCP and LCP light as plotted in Fig. and, respectively. We observe, except in the limiting cases of θ = 0 and θ = π, that F (RCP) mn (t) ̸ = -F (LCP) mn (t), indicating that inverting the polarization of the pulse will not simply shift the direction of the exciton flux, but will also affect the magnitude of flux at a given time.
