论文摘要
在本文中，我们研究了两种原子系统的动力学，该系统将其与矩形横截面耦合到准二维波导。波导支持不同的TM和TE模式，而前者则通过按需选择原子的偶极力矩作为环境发挥作用。这种环境引起原子的相互作用和集体耗散。当两个原子中的两个都位于波导的中间时，我们会观察到一种延迟效果，该效应通过移动一个原子以不为中心而打破。为了通过黑暗状态机制保留系统的完全耗散，我们提出了一种方案，其中原子的连接垂直于波导的轴。我们希望我们的研究将在基于状态到ART波导结构的量子信息处理中有用。
In this paper, we investigate the dynamics of a two-atom system which couples to a quasi-one dimensional waveguide with rectangle cross section. The waveguide supports different TM and TE modes and the former ones play as environment by on-demand choosing the dipole moment of the atoms. Such environment induces the interaction and collective dissipation of the atoms. When both of the two atoms are located in the middle of the waveguide, we observe a retardation effect, which is broken by moving one of the atom to be off-centered. To preserve the complete dissipation of the system via dark state mechanism, we propose a scheme where the connection of the atoms are perpendicular to the axis of the waveguide. We hope our study will be useful in quantum information processing based on state-to-art waveguide structure.
