【摘要】 以具有PT对称性的一维耦合多腔阵列为研究对象,主要研究散射核中腔的数量为5时单光子的散射行为,以及在散射核中心腔中有原子时对单光子散射的影响.将5个腔核的结果与3个腔核的结果进行了对比.发现合理的调节散射核中腔的数量、增益率(耗散率)、散射核的耦合系数以及加入原子可以很好地调控单光子的传输.更多还原

【Abstract】 The photonic scattering was discussed on a PT-symmetric multi-cavity array the number of whose scattering nucleu is five.As well the influence of a two-level atom which was prepared in the central cavity on the scattering was analyzed.Then the results were compared with those obtained in the case of three-cavity nucleu.It is found that the photonic scattering can be well-controlled by adjusting the number of scattering cavities and the gain rate(dissipation rate),the coupling coefficient of nucleu,as well as the atomic interaction.更多还原
