Research Overview

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.

Research Areas

  • 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.
