Ultracold mercury as a probe for physics beyond the standard model — •Sascha Heider, Thorsten Groh, and Simon Stellmer — Physikalisches Institut, Universität Bonn, Nußallee 12, 53115 Bonn, Germany

Mercury, being one of the heaviest laser-coolable elements, is an ideal platform for beyond standard model physics like baryon asymmetry searches and isotope shift spectroscopy by exploring its relativistic nucleus and the large number of naturally occurring isotopes, all of which we laser cool in our lab.

We report on recent improvements and upgrades to the machine for transferring magneto-optically trapped mercury atoms to a high power optical dipole trap as a step towards degenerate quantum gases of mercury and measurements of the atomic electric dipole moment.

Keywords: electric dipole moment; beyond standard model physics; optical dipole trap; UV transitions; magneto optical trap
