论文摘要
研究浸入超速原子浴的激光冷却离子的实验设置合并了两个令人兴奋且完善的量子气体和捕获离子的领域。这些实验受益于对几个体体离子系统的精致读出和控制，以及多体方面，可调相互作用和原子的超低温度。但是，将这两种结合起来导致实验设计和可以研究的物理学的挑战。然而，这些系统为离子原子碰撞，离子的缓冲气体冷却以及离子原子相互作用中的量子效应提供了见解。这使他们有望进行超低量子化学研究，创建用于光谱和精确测量的冷分子离子，以及作为带电杂质物理学的量子模拟的测试床。在这篇综述中，我们旨在提供有关最新进度的实验说明，并介绍实验设置和技术，从而可以观察量子效应。
Experimental setups that study laser-cooled ions immersed in baths of ultracold atoms merge the two exciting and well-established fields of quantum gases and trapped ions. These experiments benefit both from the exquisite read-out and control of the few-body ion systems as well as the many-body aspects, tunable interactions, and ultracold temperatures of the atoms. However, combining the two leads to challenges both in the experimental design and the physics that can be studied. Nevertheless, these systems have provided insights into ion-atom collisions, buffer gas cooling of ions and quantum effects in the ion-atom interaction. This makes them promising candidates for ultracold quantum chemistry studies, creation of cold molecular ions for spectroscopy and precision measurements, and as test beds for quantum simulation of charged impurity physics. In this review we aim to provide an experimental account of recent progress and introduce the experimental setup and techniques that enabled the observation of quantum effects.
