摘　　要：基于对一维半无限超导波导中的动态Casimir效应的研究,并利用系统主方程进一步推导出考虑耗散后系统的协方差矩阵,在此基础上根据Mari等人提出的量子同步判据,讨论了动态Casimir光子的量子同步效应.并分析了系统中的各个参数对系统量子同步效应的影响.结果表明,降低温度、减小失谐与归一化振幅均可缩减系统到达同步的时间,提高系统同步水平.This paper is based on the study of the dynamic Casimir effect in a one-dimensional semi-infinite superconducting waveguide,and uses the system s main equation to further derive the covariance matrix of the system after considering dissipation.Based on the quantum synchronization criterion proposed by Mari et al.,the quantum synchronization effect of dynamic Casimir photons is discussed.The effects of various parameters of the system on the system s quantum synchronization effect are analyzed in detail.It is concluded that lowering the temperature,reducing the mismatch and the normalized amplitude can reduce the time for the system to reach synchronization and improve the synchronization level of the system.
