Research will be undertaken in the field of laser cooling and trapping, particularly in studying the interactions between atoms in this ultra-low energy sub-milli Kelvin temperature regime. These include direct (collisional) interactions such as associative ionization, radiative association, and charge exchange and indirect radiation effects such as super-radiance and radiation trapping. One project is to create a sample of ultra-cold dense Rydberg atoms and trap them using DC electric fields. It may be possible to observe a phase transition (Mott transition) from an insulator to a metal when the size of Rydberg atoms becomes a significant fraction of the average interatomic spacing.

将在激光冷却领域开展研究 特别是在研究 原子在这个超低能量的亚毫开尔文温度下 政权 这些包括直接（碰撞）相互作用， 如缔合电离、辐射缔合和电荷 交换和间接辐射效应，如超辐射 和辐射捕获。 一个项目是创建一个样本， 超冷的致密里德伯原子，并使用直流电捕获它们 领域的 可以观察到相变（Mott 过渡）从绝缘体到金属时的大小 里德伯原子成为平均原子数的一个重要部分 原子间距
