论文摘要
抛物面镜中电磁场的每种自然模式都表现出空间定位和极化特性，可以利用这些特性，用于量子控制其与原子系统的相互作用。定位区域不仅限于镜像的重点，从而导致被困在其附近的原子系统的选择性响应。我们报告了被困在镜子内部的原子的自发排放速率的计算，该原子占所有原子极化和各种诱捕区域的计算。结果表明，在深层抛物面镜的焦点附近可以增强电偶极转变，并清楚地识别涉及的少数矢量模式。从重点出发，增强功能逐渐消失，但相关模式的数量仍然很少。最终，这代表了一个量子电动力系统，其中内部和外部自由度合作以最大程度地进行选择性交换和对单个激发的检测。
Each natural mode of the electromagnetic field within a parabolic mirror exhibits spatial localization and polarization properties that can be exploited for the quantum control of its interaction with atomic systems. The region of localization is not restricted to the focus of the mirror leading to a selective response of atomic systems trapped on its vicinity. We report calculations of the spontaneous emission rates for an atom trapped inside the mirror accounting for all atomic polarizations and diverse trapping regions. It is shown that electric dipole transitions can be enhanced near the focus of a deep parabolic mirror with a clear identification of the few vectorial modes involved. Out of the focus the enhancement vanishes gradually, but the number of relevant modes remains small. Ultimately this represents a quantum electrodynamic system where internal and external degrees of freedom cooperate to maximize a selective exchange and detection of single excitations.
