摘要：
The two-exciton dynamics in a dendritic molecular aggregate composed of monomers coupled with each other by the dipole-dipole interaction is performed to investigate the effect of two-exciton states on the exciton migration using the master equation approach. Although the spatial unique feature of exciton migration from the periphery to the core in the one-exciton model is also observed in the two-exciton model, about 36% of such exciton migration is found to be carried out by the relaxation among two-exciton states in the present model.
