Research Group - Molecular Quantum Gases

This research group focuses on the study of ultracold molecules and quantum gases of polar molecules. Ultracold molecules offer promising perspectives as novel quantum many-body systems with a complex and interesting interaction, as highly controllable systems for the study of chemical processes at the quantum limit and as objects for precision measurements.
