- Our results on ultracold chemistry are published in Science 358, 921 (2017). Using a novel method we have quantum state-selectively probed the molecular products of a chemical reaction with unprecedented resolution and in a quantitative fashion. As model system we have investigated three-body recombination of neutral Rb atoms. From our measurements it was possible to derive propensity rules for the population of the product states.
- Using an optical lattice we have performed collision experiments with Rb2 molecules. For different well-defined quantum states (e.g. the triplet rovibrational ground state) we have measured reaction rates. We have observed that these reaction rates depend on the confinement of the molecules and the collision energy. This might be exploited in future to control chemical reactions. The results are published in Nat. Commun. 8, 14854 (2017).
- We offer a PhD position at the rubidium experiment: In the new project, ultracold chemical reactions will be controlled and detected using an optical microcavity for the first time.

- In our Rubidium Lab we were able to create an ensemble of aligned molecules in an optical lattice which has been probed using a novel method.
The results are published in Phys. Rev. Lett. 113, 233004 (2014).
