Towards high-precision EDM measurements of ultracold mercury — •Thorsten Groh and Simon Stellmer — Physikalisches Institut, Nussallee 12, Universität Bonn, 53115 Bonn, Germany

The baryon asymmetry of the universe explained by recent baryogenesis therories requires a degree of CP-violation that exceeds the value predicted by the Standard Model by several orders of magnitude. Such a large CP-violation would result in a sizeable permanent electric dipole moment (EDM) of fundamental particles and might reflect in an atomic EDM whose magnitude is within the sensitivity of future experiments. We report on a new experimental apparatus for the generation of ultracold gases of mercury. For loading a three-dimensional magneto-optical trap (λ=254 nm) we employ a spatially separate high-flux low-velocity atomic source. This scheme should allow the generation of large statistical samples while still achieving ultra-high vacuum conditions in the science chamber and therefore fulfilling the demands for beyond the state-of-the-art high-precision measurements of the atomic EDM of mercury.
