Controlling single Cs atoms with a Rb condensate

我们的项目将解决以下更普遍的物理问题：在原子的小样本水平上，多粒子概念是以何种方式反映出来的？玻色凝聚能用来控制少量杂质原子的性质吗？我们能确定性地创造出单个分子吗？这一时期的具体项目：系统研究Rb-Cs相互作用和测定s波散射长度;寻找Feshbach共振;观察RbCs分子的形成;将少量Cs原子注入Rb凝聚体并进行观察。长期目标：确定性地产生单个RbCs分子。

Our project will address the following more general physical questions: In which way are many-particle concepts reflected at the level of small samples of atoms? Can Bose condensates be used to control the properties of a small number of impurity atoms? Can we deterministically create a single molecule? Specific Projects for this period: Systematic study of the Rb-Cs interaction and determination of the s-wave scattering length; Search for Feshbach resonances; Observation of the formation of RbCs molecules; Implantation and observation of a small number of Cs atoms into a Rb condensate. Longterm goal: Deterministic creation of a single RbCs molecule.
