Spectroscopy of Rydberg states in ultra cold ytterbium — •Christian Halter, Apoorva Hedge, Mustafa Jumaah, Christian Sillus, Thomas Burg, and Axel Görlitz — Heinrich-Heine-Universität Düsseldorf

Understanding the special features of Rydberg atoms, e.g. dipole-dipole interaction or van-der-Waals blockade, has become of utmost importance in quantum optics. Particularly ultra cold Rydberg atoms are of great interest for the investigation of long range interactions. Hence, in the present study, ultra cold ytterbium is spectroscopically investigated to gain precise knowledge on the Rydberg states. A special feature of ytterbium is that due to its two valance electrons atoms in Rydberg state can be easily manipulated and imaged using optical fields. For the above-mentioned spectroscopy an induced loss of atoms in a magneto-optical trap (MOT), that is caused by the Rydberg excitation, is used to detect the Rydberg states. Applying this method, we could measure several energy levels of Rydberg states in ultra cold ytterbium.
