Event Details & Abstract: 

The alkaline-earth element strontium has a rich electronic structure comprising metastable states, broad and narrow linewidth transitions, and a ground state free of electronic magnetic moment. We exploit these properties to create a Bose-Einstein condensate by using laser cooling as the only cooling mechanism. Variations of our technique might in the future enable the construction of a truly continuous atom laser. Furthermore I will present the creation of quantum degenerate Rb-Sr mixtures, for which sympathetic cooling of Rb by laser cooled Sr plays a crucial role. We intend to create RbSr ground-state molecules, which are open-shell polar molecules, providing a large control parameter space for ultracold chemistry and the study of many-body physics.
