We work in the field of experimental Atomic, Molecular and Optical Physics. One major effort involves leveraging the techniques of precision metrology to look for evidence of new particle physics. A second effort makes use of ultralow temperature atomic gases to explore few- and many-body quantum physics.
In this experimental collaboration with the Ye group (previously with the Jin group) we use an ultracold gas of Rb85 to create a strongly interacting Bose Einstein Condensate. Rb85 has a magnetic Feshbach resonance that can be tuned to create very strong interactions similar to that which can be found in a superfluid, such as liquid helium. We have recently equipped our new generation BEC machine with K39 in addition to Rb85, both of which will provide an ideal platform to study few- and many-body…
The purpose of this experiment is to make a precision measurement of the electic dipole moment (EDM) of the electron. Because a finite electron EDM violates time symmetry, and thus by the CPT theorem violates CP symmetry as well, a precision upper bound on an electron EDM constrains modelbuilders. In this experiment we use trapped HfF+ molecular ions and use the intermolecular electric field to greatly enhance a potential electron EDM signal.
