摘要

研究了具有激子跳变随机性的一维分子集合体的动力学特性。我们发现,聚集体激子跳跃符号分布的随机性极大地改变了动态特性。在同质情况下,分子集合体的动力学特征表现为集合体弗伦克尔激子带边缘的窄线。另一方面,我们证明所考虑的随机性会对带内所有激子的动态特性产生非零贡献。

Dynamical characteristics of inhomogeneous molecular aggregates
The dynamical characteristics of one-dimensional molecular aggregate with the randomness in exciton hopping is considered. We show that the randomness of the distribution of signs of the exciton hopping of the aggregate dramatically changes the dynamical characteristics. In the homogeneous case, the dynamical characteristics of the molecular aggregate manifest narrow lines at edges of the band of Frenkel excitons of the aggregate. On the other hand, we show that the considered randomness yields nonzero contributions to the dynamical characteristics of all excitons of the band.
