论文摘要
我们在实验上证明了一维单原子阵列与高技能微型腔之间的强耦合。通过将单个原子加载到1D光学镊子阵列中，尺寸为1 $ \ times $ 11来获得原子阵列。因此，获得确定数量的原子数，并且原子数是通过实时成像CCD摄像机上的原子阵列来确定的。通过精确控制原子阵列在高技巧fabry中的位置和间距 - 孔洞，阵列中的所有原子都会同时与空腔相结合。真空狂犬分裂光谱被区分为确定性原子数，从1到8，而$ \ sqrt {n} $依赖性的耦合强度对原子数$ n $的集体增强的依赖性在单原子级别进行了验证。
We experimentally demonstrate strong coupling between a one-dimensional (1D) single-atom array and a high-finesse miniature cavity. The atom array is obtained by loading single atoms into a 1D optical tweezer array with dimensions of 1$\times$11. Therefore, a deterministic number of atoms is obtained, and the atom number is determined by imaging the atom array on a CCD camera in real time. By precisely controlling the position and spacing of the atom array in the high finesse Fabry--Perot cavity, all the atoms in the array are strongly coupled to the cavity simultaneously. The vacuum Rabi splitting spectra are discriminated for deterministic atom numbers from 1 to 8, and the $\sqrt{N}$ dependence of the collective enhancement of the coupling strength on atom number $N$ is validated at the single-atom level.
