INTERACTIONS AND COLLISIONS IN ULTRACOLD RYDBERG GASES AND PLASMAS

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和可能破坏它们的碰撞过程，如三体复合。 工作的第一部分利用这些系统的群属性，并在很大程度上依赖于量子亏损理论提供一些半解析结果。 对复合的研究采用了PI多年前在气体放电物理学背景下开创的技术的修改。

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.
