双量子点中的集体发光和声子诱导过程

Collective luminescence and phonon-induced processes in double quantum dots

Paweł Machnikowski, Katarzyna Roszak, Anna Sitek

摘要:

研究了双量子点系统在电磁环境和晶格模相互作用下,当两个量子点之间存在耦合时,系统的量子态的演化。我们提出了一个统一的方法来模拟两个水库联合影响下的系统演化。我们讨论了亚辐射和超辐射的辐射衰减系统,声子诱导的点之间的纠缠衰减,和它们之间的激发转移。

英文摘要:

We study the evolution of a quantum state of a double quantum dot system interacting with the electromagnetic environment and with the lattice modes, in the presence of a coupling between the two dots. We propose a unified approach to the simulation of the system evolution under joint impact of the two reservoirs. We discuss the sub- and superradiant radiative decay of the system, the phonon-induced decay of entanglement between the dots, and the transfer of excitation between them.
