论文摘要
我们证明了一个85RB原子在距离耳语 - 盖尔式模式瓶微孔子表面距离为200 nm的距离。该原子被困在光电位中，该原子是通过从谐振器表面反射反射的重点激光束而产生的。我们通过使用适当选择的功率和失调的第二激光束超级粘液来抵消原子过渡频率的陷阱引起的光移。这使我们能够在耦合原子谐振系统的激发光谱中观察真空狂犬病。在强耦合方案中，单个原子与窃窃私语模式的稳定和受控相互作用的首次证明为实施量子方案和应用的途径开辟了途径，这些方案和应用收集了这类谐振剂中存在的手性原子 - 光耦合。
We demonstrate trapping of a single 85Rb atom at a distance of 200 nm from the surface of a whispering-gallery-mode bottle microresonator. The atom is trapped in an optical potential, which is created by retroreflecting a red-detuned focused laser beam from the resonator surface. We counteract the trap-induced light shift of the atomic transition frequency by superposing a second laser beam with suitably chosen power and detuning. This allows us to observe a vacuum Rabi-splitting in the excitation spectrum of the coupled atom-resonator system. This first demonstration of stable and controlled interaction of a single atom with a whispering-gallery-mode in the strong coupling regime opens up the route towards the implementation of quantum protocols and applications that harvest the chiral atom-light coupling present in this class of resonators.
