Description
I will present a brief overview of current research activities in my group at the Institute for Quantum Matter at the University of Ulm. A main focus point of our experiments is cold chemistry where ultracold atoms combine to form diatomic molecules or more general bound states. We have developed experimental methods to precisely determine the quantum states of these bound states. Using these methods, we can learn how the cold reactions work on a fundamental level and we can test novel ways to coherently control the reaction processes. Tools for this control can be, e.g., magnetically tunable scattering resonances, laser radiation, as well as optical cavities. The types of bound states we produce and study range from weakly-bound dimeric molecules in the electronic ground state, to highly-excited ultralong-range Rydberg molecules, to many-body bound states in a fermionic atomic gas. Finally, I will also introduce an additional project of ours where we want to use holography for imaging atoms in an optical lattice.
