Description:

Abstract: Despite its triumphs, the Standard Model cannot explain, among other things, why our universe contains more matter than antimatter. So far, all our most valiant efforts to unveil the source of this asymmetry have failed. Giant accelerators, subterranean observatories and precision measurements have yet to detect new whispers from the darkness. In these trying times, the solid state beckons as a new frontier for precision. The EDM3 experiment aims to probe physics at the PeV scale on a tabletop by measuring the electron’s electric dipole moment (eEDM) using molecules trapped in inert gas crystals. In this talk, I’ll detail our group’s most recent results towards the development of this experiment. I will focus on our studies of optical pumping and RF transitions in BaF-doped neon crystals, as well as on my own work towards growing and characterizing crystals of the extreme purity necessary for a measurement of the eEDM.
