局域二能级系统的一维双光子散射

Two-Photon Scattering in One Dimension by Localized Two-Level System

T. Shi, C. P. Sun

摘要:

研究了一维耦合谐振腔阵列中双光子与局域化的量子控制器二能级系统的散射。$S$矩阵是通过TLS针对各种双光子散射过程解析计算的,例如,一个光子被TLS限制以形成束缚态,而另一个光子处于散射态。从$S$ -矩阵的极点发现,存在两种描述两个束缚光子局域在TLS周围的三体束缚态。

英文摘要:

We study two-photon scattering in a one-dimensional coupled resonator arrays (CRA) by a two-level system (TLS), which is localized as a quantum controller. The $S$-matrix is analytically calculated for various two-photon scattering processes by TLS, e.g., one photon is confined by TLS to form a bound state while the other is in the scattering state. It is discovered from the poles of the $S$-matrix that there exist two kinds of three-body bound states for describing two bound photons localized around TLS.
