Outline of Final Research Achievements

In order to search for EDM in a diamagnetic atom Xe-129, which if present will constitute an undeniable evidence for physics beyond the Standard Model, we have conducted frequency stabilization studies and co-magnetometer development.
As a result, a co-running spin maser of Xe-131, a spin 3/2 isotope of Xe-129, has been proven to serve as an excellent co-magnetometer with high compensation powers against the magnetic field and Rb density drifts. A digitalized feedback architecture and temperature stabilization systems have been implemented. Thus, all the factors perceived to cause the frequency drifts became under control, but at the same time, this has disclosed the presence of another effect causing the drift, i.e., the spin phase deviation of Rb from Xe due to the feedback field. A method to avoid this effect has been proposed and its validity demonstrated, thus indicating a prospect for an order of magnitude improvement from the present experimental upper limit on the Xe-129 EDM.
