Rydberg Spectroscopy of Ultracold Ytterbium

Apoorva Hedge
University of Düsseldorf

The interesting features of Rydberg atoms have made them very desirable for research in atomic physics, in studying strongly interacting Rydberg gases, dipole interactions between Rydberg atoms, Rydberg atom blockade and so on. Creation of Rydberg states in ultracold systems could be of significance due to their long range interactions. In this presentation, Rydberg excitation of ytterbium that has been enabled using the techniques of laser cooling and trapping is discussed. The experimental setups for cooling the ytterbium atoms in a magneto-optical trap and further exposing them to the light required for the Rydberg transition is explained, followed by a brief account on the data that has been obtained so far.
