Selection of dominant multi-exciton transitions in disordered linear J-aggregates
arXiv:0707.0826 · doi:10.1016/j.jlumin.2007.11.052
Abstract
We show that the third-order optical response of disordered linear J-aggregates can be calculated by considering only a limited number of transitions between (multi-) exciton states. We calculate the pump-probe absorption spectrum resulting from the truncated set of transitions and show that, apart from the blue wing of the induced absorption peak, it agrees well with the exact spectrum.
