Ultracold Collisions in Traps, Beams, and Condensates

这个研究项目探索利用光场来操纵原子碰撞。这项工作有两个主要目标，超冷分子的产生和捕获以及玻色-爱因斯坦凝聚体及其附近的超冷碰撞光谱，尽管铷原子的光结合电离的连续动力学和光学屏蔽和抑制的极化各向异性的研究将发挥作用。所有的过程都依赖于原子被激发到与分子间电位曲线有特定关系的选定状态，这样键的形成和断裂就能以一种精心控制的方式发生。

This research program explores the use of optical fields to manipulate atomic collisions. The work has two principal goals, production and trapping of ultracold molecules and ultracold collision spectroscopy in and near a Bose-Einstein condensate, although studies in continuum dynamics in the photoassociative ionization of rubidium atoms and polarization anisotropy of optical shielding and suppression will play a part. All processes rely on the excitation of atoms to selected states that have specific relationships to the intermolecular potential curves, such that bond formation and breaking can occur in a carefully controlled manner.
