On the Possibility of Electric Dipole Moments for Elementary Particles and Nuclei
Published on this day 75 years ago is the paper by Edward M. Purcell and Norman F. Ramsey that launched search for the permanent electric dipole moment (EDM) neutrons, electrons, atomic nuclei, and other elementary particles such as muons. Ramsey recounts the story of how this paper and the first…

Preprint of EDM Review Paper posted to arXiv:1710.02504
This paper has been seven years in the making and counting. I have only participated in the last two and half years of this massive undertaking and found the process to be profoundly humbling. I am tremendously relieved to see this posted online and am looking forward to all of the feedback…

Fundamental Symmetries of the Early Universe and the Origin of Matter
This week I hosted Prof. Michael Ramsey-Musolf, Director of the Amherst Center for Fundamental Interactions, who was visiting from UMass.-Amherst to give the MSU P&A Colloquium on “Fundamental Symmetries of the Early Universe and the Origin of Matter.” Abstract: Explaining why the universe contains more matter than antimatter remains an open problem…

This technical note by Lee & Yang, first published in October 1957, is based on a series of lectures given in January 1957. Of particular note is “Section III.4 Static Electric Dipole Moment” on page 17 which indicated, perhaps for the first time, that non-zero EDMs would violate not only…

CUSTIPEN-IMP-PKU Workshop on Physics of Exotic Nuclei
I was asked to give a talk on “The Search for Electric Dipole Moments Using Octupole-Deformed Nuclei” @ the Workshop on Physics of Exotic Nuclei in Huizhou, Guandong, China. This is the first public talk I’ve given on our concept for a Protactinium-229 EDM search in the FRIB era. While in China,…
