论文摘要
杂质物理学是当今凝结物理学的传统话题，如今，在超低气体领域正在探索。在不同类别的杂质中，我们专注于超速浴中的充电杂质。当单个离子与超电气气体接触时，会经过不同的反应性过程，可以从冷化学方法中理解。在这项工作中，我们介绍了在超低原子或分子浴中单个离子动力学的方法，并补充了凝结物理学中杂质物理的常规多体方法的特征。特别是，我们专注于不同浴缸中带电的杂质的演变，包括外部时间依赖性的捕获电位，我们探索了离子中性混合陷阱中存在的外部激光源的效果，使其成为杂质的寿命。
Impurity physics is a traditional topic in condensed matter physics that nowadays is being explored in the field of ultracold gases. Among the different classes of impurities, we focus on charged impurities in an ultracold bath. When a single ion is brought in contact with an ultracold gas it is subjected to different reactive processes that can be understood from a cold chemistry approach. In this work, we present an outlook of approaches for the dynamics of a single ion in a bath of ultracold atoms or molecules, complementing the usual many-body approaches characteristic of impurity physics within condensed matter physics. In particular, we focus on the evolution of a charged impurity in different baths, including external time-dependent trapping potentials and we explore the effect of the external laser sources present in ion-neutral hybrid traps into the lifetime of an impurity.
