Electron EDM measurements in molecules: What current limits mean, and how we are moving forward.
ORAL · Invited
Abstract
In the wake of JILA's record-sensitivity limit set on the electron’s electric dipole moment that appeared last summer, we have been working on a new-generation apparatus to extend sensitivity still farther. I will put recent measurements of magnetic and electric dipole moments on an equal footing with respect to the search for physics beyond the standard model. Looking forward, I will discuss the various effects that stand in the way of realizing a 20-second coherence time in trapped-molecule spectroscopy, and I will explain how we hope to derive the largest possible metrological advantage from the coherence time we are able to achieve.
