三体耦合腔环形阵列的PT相变和光子传输研究

Study on PT phase transition and single-photon transmission in a three-body coupled cavity array

针对三体耦合腔环形阵列的PT相变及光子局域化的动力学特征进行了研究.结果表明:当体系处在不同量子态时,不仅会对PT相变产生影响,即存在2个PT相变的临界参数,而且还会对体系透射性能产生影响,即本征模关于横轴的不对称性.

The dynamic characteristics of PT phase transition and photon localization of three-body coupled cavity ring arrays are discussed in detail. When the system is in different quantum states,there are two critical parameters for PT phase transition. Moreover,the transmission property of the system is affected by the asymmetry of the intrinsic mode respective to the transverse axis.
