在周期外场驱动下,对两个量子点的系统的动力学进行了研究,根据Floquet定理并引入时间演化算符进而求得系统的准能,通过分析系统准能的变化情况,对系统激子态的演化和纠缠进行了讨论.
The exciton dynamics of two coupled Quantum-dot driven by the time-periodic field was investigated. By diagonalizing the evolution operator, we calculated the quasienergies, through which the evolution behavior and quantum entanglement of the exciton dynamics were revealed.
