The research involves two, complementary aspects of the interactions of ultracold excited atoms; the formation of weakly bound molecular states formed from highly excited Rydberg atoms and the collisional process that may destroy them, such as three-body recombination. The first part of the work exploits the group properties of these systems and relies heavily on quantum defect theory to provide some semi-analytic results. The research on recombination employs modifications of echniques that were pioneered by the PI many years ago in the context of gas discharge physics.

该研究涉及超冷激发原子相互作用的两个互补方面；由高度激发的里德伯原子形成的弱束缚分子态的形成以及可能破坏它们的碰撞过程，例如三体重组。 这项工作的第一部分利用了这些系统的群属性，并在很大程度上依赖于量子缺陷理论来提供一些半解析结果。 复合研究采用了 PI 多年前在气体放电物理背景下首创的技术改进。
