标题： Light-Assisted Collisions in Tweezer-Trapped Lanthanides

摘要： 我们对在光学镊子中暴露于近共振光下的少数铒原子发生的一体和二体光介导过程进行了定量研究。 为了研究反冲加热、冷却以及光辅助碰撞的相互作用效应，我们开发了一种基于第一性原理的蒙特卡罗算法，该算法可以求解原子内部和外部自由度的耦合动力学。 在用实验数据验证我们的理论模型后，我们利用代码的预测能力来指导实验，并且特别研究了铒的不同跃迁在光辅助碰撞方面的效率和单原子制备保真度。 显示英文摘要

摘要： We present a quantitative investigation of one- and two-body light-mediated processes that occur to few erbium atoms in an optical tweezer, when exposed to near-resonant light. In order to study the intertwined effects of recoil heating, cooling and light-assisted collisions, we develop a first-principles Monte Carlo algorithm that solves the coupled dynamics of both the internal and external degrees of freedom of the atoms. After validating our theoretical model against experimental data, we use the predictive power of our code to guide our experiment and, in particular, we explore the performance of different transitions of erbium for light-assisted collisions in terms of their efficiency and fidelity for single-atom preparation.
