双量子点中辐射和声子诱导的退相

Radiative and phonon-induced dephasing in double quantum dots

Paweł Machnikowski

摘要:

提出了一种描述双量子点系统同时与电磁环境和晶格模相互作用时量子态演化的简单方法。结果表明,这两个水库的联合行动导致非平凡的影响,在系统的失相。作为例子,讨论了声子诱导的初始退相对离域激子态辐射衰减的影响。

英文摘要:

A simple method for describing the evolution of a quantum state of a double quantum dot system interacting simultaneously with the electromagnetic environment and with the lattice modes is developed. It is shown that the joint action of the two reservoirs leads to nontrivial effects in the system dephasing. As an example, the impact of phonon-induced initial dephasing on the radiative decay of delocalized exciton states is discussed.
