"The Ongoing Radium EDM Experiment"

ABSTRACT:
Radium, due to its simple atomic structure, heavy mass, and large nuclear deformation, is an exciting candidate for a CP violation search in the form of an atomic electric dipole moment (EDM). Since CP violation is expected to play an important role in beyond the standard model physics, such a search is a sensitive probe of new physics. An ongoing experiment at Argonne National Lab, which aims to measure the EDM of laser cooled and trapped radium-225 atoms, has made considerable progress in recent years. Here I report the control and preparation of such atoms as well as the first observation of nuclear precession in trapped radium atoms. Together with the application of an electric field, nuclear precession is the signal that will become the first measurement of radium's EDM.
