Probing physics beyond the standard model with ultracold mercury — Thorsten Groh and •Simon Stellmer — Physikalisches Institut, Universität Bonn, Germany

Ultracold samples of atoms, cooled to temperatures of a few µK or even into the quantum-degenerate regime, allow for an exquisite control of all their internal and external degrees of freedom. It is this high degree of control, combined with the small size of these samples, that we want to exploit to search for physics beyond the standard model.

As a first experiment, we aim to measure the atomic EDM of mercury. Improving the sensitivity of current experiments (which operate with thermal samples) might allow us to constrain the parameter range of beyond-standard-model theories.

We are currently setting up the experiment and will report on the progress.
