Besides the conventional means of chemical reaction control, e.g., through the change of temperature and pressure, the exploitation of quantum effects offers many further possibilities for influencing the outcome of chemical processes. In recent years, we have developed laser- and magnetic-field-based techniques in order to precisely control the fate of a chemical reaction at the quantum level [1,2].

This research project involves the study of chemical reaction dynamics in the gas phase using quantum-state preparation following previous experiments with trapped ultracold atoms in Freiburg [3] and using an innovative approach for coherent control in the phase domain [4], which relies on the generation of interference in between different reaction pathways using laser fields. A designated laboratory with two existing experimental setups is available for carrying out independent experiments in this direction and beyond.
