标题： Precursors to Anderson Localization in the Holstein Model: Quantum and Quantum-Classical Solutions

摘要： 我们使用基于动态量子典型性的方法以及量子-经典方法，在接近绝热极限的情况下计算了一维Holstein极化子的频率依赖迁移率。完全量子和量子-经典解之间的吻合非常好。最显著的特征是在迁移率中出现了零频率峰，除了与安德森局域化前驱体相关的位移峰之外。零频率峰无法通过通常用于准一维有机半导体电荷传输半定量描述的现象学瞬态局域化方法获得。 显示英文摘要

摘要： We calculate the frequency-dependent mobility of the Holstein polaron in one dimension near adiabatic limit using the method based on dynamical quantum tipicality, as well as the quantum-classical method. The agreement between fully quantum and quantum-classical solutions is very good. The most prominent feature is the appearance of a zero-frequency peak in the mobility, in addition to the displaced peak associated to the precursors of Anderson localization. The zero-frequency peak cannot be obtained within the phenomenological transient localization approach, which is often used in a semiquantitative description of charge transport in quasi-one-dimensional organic semiconductors.
