论文摘要

我们意识到,在元素周期表的主要组III中,第一个原子较慢,也称为“ Triel Elements”。尽管我们选择的原子(即indium)没有适合激光冷却的基态循环过渡,但通过驱动过渡$ \ lvert 5p_ {3/2}来实现放缓,f = 6 \ rangle \ rangle \ ranglearrow \ rightArrow \ rightarrow \ lerver \ lvert 5d_ {5/2} {5/2},f = 7 \ f = 7 \ rangle $ ser-rangle $ $,以下是rangle $,gater-gater-gety。使用基于横向场构型的永久磁体较慢的速度,我们在设计目标速度为70 m/s时观察到明亮的原子束的速度放缓。此处介绍的技术可以直接延伸到其他Triel原子,例如thallium,Aluminum和Gallium。此外,这项工作打开了冷却III原子的可能性,以至于超低温度。

We realize the first Zeeman slower of an atom in the Main Group III of the periodic table, otherwise known as the "triel elements". Despite that our atom of choice (namely indium) does not have a ground state cycling transition suitable for laser cooling, slowing is achieved by driving the transition $\lvert 5P_{3/2},F=6 \rangle \rightarrow \lvert 5D_{5/2},F=7 \rangle$, where the lower-energy state is metastable. Using a slower based on permanent magnets in a transverse-field configuration, we observe a bright slowed atomic beam at our design goal velocity of 70 m/s. The techniques presented here can straightforwardly extend to other triel atoms such as thallium, aluminum, and gallium. Furthermore, this work opens the possibility of cooling Group III atoms to ultracold temperatures.
