耦合陷阱团中极化激元纠缠的非平衡动力学

Nonequilibrium dynamics of polariton entanglement in a cluster of coupled traps

L. Quiroga, C. Tejedor

摘要:

详细研究了耦合极化激元陷阱系统中量子相干性(纠缠)的产生和弛豫。利用基于李代数的超算子技术,我们给出了该系统的马尔可夫耗散动力学(Master方程)的解析精确解,该解适用于任意团簇大小、极化激元-极化激元相互作用强度、温度和初始状态.基于Master方程在T= 0 K时的精确解,我们讨论了耗散对耦合极化激元系统量子纠缠动力学的影响。

英文摘要:

We study in detail the generation and relaxation of quantum coherences (entanglement) in a system of coupled polariton traps. By exploiting a Lie algebraic based super-operator technique we provide an analytical exact solution for the Markovian dissipative dynamics (Master equation) of such system which is valid for arbitrary cluster size, polariton-polariton interaction strength, temperature and initial state. Based on the exact solution of the Master equation at T=0K, we discuss how dissipation affects the quantum entanglement dynamics of coupled polariton systems.
