Structure and Dynamics of Excited Atoms

Abstract

During the grant period we focused on the use of microwaves to manipulate and probe interacting atoms. Cold Rydberg atoms in a magneto optical trap (MOT) are randomly spaced, leading to a large variation in the dipole-dipole interaction strength, and, in general, cusp shaped energy transfer resonances. We demonstrated that driving one microwave transition, for example ns-(n-1)p, we could remove ns atoms with selected spacings, allowing the ns-np to be observed without the deselected atoms. Removing widely spaced ns atoms results in a Lorentzian line shape.
