无序线性J-聚集体中多激子优势跃迁的选择

Selection of dominant multi-exciton transitions in disordered linear J-aggregates

J. A. Klugkist, V. A. Malyshev, J. Knoester

摘要:

我们表明,无序线性J-聚集体的三阶光学响应可以通过只考虑有限数量的(多)激子态之间的跃迁来计算。我们计算的泵浦-探测吸收光谱产生的截断设置的过渡,并表明,除了蓝翼的诱导吸收峰,它同意以及与确切的光谱。

英文摘要:

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.
