Strongly-correlated gases of ultracold strontium Rydberg atoms

In our laboratory we produce and study ultracold gases of strontium atoms which we subsequently excite to high-lying electronic (Rydberg) states. Strontium, as an earth-alkaline element, offers different features as compared to alkali atoms, which are commonly used in experimental ultracold atomic physics. It is our plan to pursue the study of strongly interacting Rydberg gases, taking advantage of an efficient BEC formation scheme, and possibly using an optical lattice for Rydberg atoms or an autoionization detection scheme.

Our laboratory is based at the Shanghai Institute of Advanced Studies. Here we are embedded into the Division of Quantum Physics and Quantum Information of the University of Science and Technology of China (USTC). Our Chinese-European mixed team is the result of a fruitful collaboration with the Quantum Dynamics group at the Physikalisches Institut of the University of Heidelberg, Germany.
