均匀填充的中性原子阵列的快速产生
Rapid production of uniformly-filled arrays of neutral atoms
摘要：
我们展示了快速加载的一个小阵列的光镊与一个单一的$^{87}$ Rb原子每个网站。我们发现，负载效率高达90%，每镊子是在不到170毫秒的陷阱分离超过$1.7 \,μ\text{m}$。有趣的是，我们发现负载效率是由附近的陷阱和目前的效率作为两个光镊之间的间距的函数。这种增强的负载，结合随后的填充位点的重新排列，将使量子多体系统的研究通过量子气体组装。
英文摘要：
We demonstrate rapid loading of a small array of optical tweezers with a single $^{87}$Rb atom per site. We find that loading efficiencies of up to 90% per tweezer are achievable in less than 170 ms for traps separated by more than $1.7 \,μ\text{m}$. Interestingly, we find the load efficiency is affected by nearby traps and present the efficiency as a function of the spacing between two optical tweezers. This enhanced loading, combined with subsequent rearranging of filled sites, will enable the study of quantum many-body systems via quantum gas assembly.
