我们演示了单个离子在小质量超冷原子缓冲气体中的交感冷却。通过抑制碰撞加热，实现了高效碰撞冷却。我们尝试用一个简单的速率方程模型来解释实验结果，并对每次碰撞的冷却效率进行了定量的讨论。我们在这项工作中获得的知识是推进中性原子与离子共振冷却技术的重要组成部分。
We demonstrated sympathetic cooling of a single ion in a buffer gas of ultracold atoms with small mass. Efficient collisional cooling was realized by suppressing collision-induced heating. We attempt to explain the experimental results with a simple rate equation model and provide a quantitative discussion of the cooling efficiency per collision. The knowledge we obtained in this work is an important ingredient for advancing the technique of sympathetic cooling of ions with neutral atoms.
