I joined the Physics Division Colloquium at Argonne this morning. Dr. Eric Cornell, 2001 Nobel Prize winner presented a great talking about his resent research on electron electric dipole moment (eEDM).
Searching for the Electron's Electric Dipole Moment in Trapped Molecular Ions
The current experimental upper bound on the electron electric dipole moment (eEDM) already cuts into the natural scale predicted by supersymmetry. I'll discuss an ongoing experiment in our lab to push experimental sensitivity down some two orders of magnitude. The effective electric fields inside a molecule can be thousands of times larger than in free space. A molecule with unpaired electron spin serves as our high-field lab for this benchtop particle physics experiment.
