Ultracold Atoms and Molecules Research

at the University of Washington

There are two main themes in our research work. In the first we cool and trap a mixture of two different atomic species (lithium and ytterbium) for studies of interacting ultracold mixtures, and preparation and studies of polar diatomic molecules. More details here and in the publications and presentations pages.
In the second, we are developing precision atom interferometers with Bose-Einstein condensates with a major goal of measuring the fine structure constant and thus testing quantum electrodynamics at the sub-part per billion level. More details here and in the publications and presentations pages.
