标题： Trap-induced atom-ion complexes: a time-independent approach

摘要： 被困离子沉浸在中性浴中会显示出长期存在的原子-离子复合物，这些复合物显著改变其化学性质，从而影响离子的稳定性。在本工作中，我们展示了对被困离子-原子散射的一般研究，其中离子被建模为其基态波函数的空间扩展所定义的电荷分布。将时变问题映射到一个时不变框架后，我们研究了陷阱、原子种类、原子-离子相互作用和碰撞能量在塑造系统混沌动力学中的作用。我们发现，原子-离子复合物形成的概率直接测量了系统的混沌程度。因此，我们的结果建立了混沌散射的出现与离子-原子复合物存在之间的明确关系。 显示英文摘要

摘要： A trapped ion immersed in a neutral bath shows long-lived atom-ion complexes that significantly alter its chemical properties, and, thus the ion stability. In this work, we present a general study of trapped ion-atom scattering with the ion modeled as a charge distribution defined by the spatial extent of its ground-state wavefunction. After mapping the time-dependent problem onto a time-independent framework, we investigate the role of the trap, the atomic species, atom-ion interaction, and collision energy in shaping the chaotic dynamics of the system. We find that the probability of atom-ion complex formation directly measures its chaoticity. Therefore, our results establish a clear relationship between the emergence of chaotic scattering and the presence of ion-atom complexes.
