摘要:

我们提出了一种方法,用于放大一个单一的或分散的杂质沉浸在背景气体的超冷原子,使他们可以光学成像和空间分辨。我们的方法依赖于两个稳定的原子超精细态之间的拉曼转移,其条件是杂质原子的存在。这种放大是基于激发到里德伯态的原子之间的强相互作用。我们进行了详细的分析研究所提出的计划的性能,特别强调多体效应的影响。

英文摘要:

We present a method for amplifying a single or scattered impurities immersed in a background gas of ultra cold atoms so that they can be optically imaged and spatially resolved. Our approach relies on a Raman transfer between two stable atomic hyperfine states that is conditioned on the presence of an impurity atom. The amplification is based on the strong interaction among atoms excited to Rydberg states. We perform a detailed analytical study of the performance of the proposed scheme with particular emphasis on the influence of many-body effects.
