标题： Concurrence of Two Identical Atoms in a Rectangular Waveguide: Linear Approximation with Single Excitation

摘要： 我们研究两个两能级系统（TLSs）与受限在矩形波导中的引导模式的环境相互作用。 对于远离横向模式截止频率的相同TLSs的能量分离，通过TLSs中的单激发初始条件得到延迟微分方程。 检查了互TLS距离对TLSs纠缠度时间演化的影响。 显示英文摘要

摘要： We study two two-level systems (TLSs) interacting with a reservoir of guided modes confined in a rectangular waveguide. For the energy separation of the identical TLSs far away from the cutoff frequencies of transverse modes, the delay-differential equations are obtained with single excitation initial in the TLSs. The effects of the inter-TLS distance on the time evolution of the concurrence of the TLSs are examined.
