库仑关联对耦合量子点局域电荷弛豫的影响

Coulomb correlations effects on localized charge relaxation in the coupled quantum dots

P. I. Arseyev, N. S. Maslova, V. N. Mantsevich

摘要:

分析了两个相互作用量子点(人工分子)与连续谱态耦合系统中局域电荷的时间演化。我们表明,库仑相互作用修改弛豫速率,并负责非单调时间演化的本地化电荷。我们提出了这种非单调的电荷时间演化的新机制,与每个量子点中不同弛豫通道之间的电荷重新分配有关。

英文摘要:

We analyzed localized charge time evolution in the system of two interacting quantum dots (QD) (artificial molecule) coupled with the continuous spectrum states. We demonstrated that Coulomb interaction modifies relaxation rates and is responsible for non-monotonic time evolution of the localized charge. We suggested new mechanism of this non-monotonic charge time evolution connected with charge redistribution between different relaxation channels in each QD.
