A Molecular Zeeman slowing scheme — •Maurice Petzold, Paul Kaebert, Philipp Gersema, Mirco Siercke, and Silke Ospelkaus — Institut für Quantenoptik, Leibniz Universität Hannover

We present our results on implementing a novel technique for slowing molecules to velocities trappable by magneto-optical traps. The scheme relies on the decoupling of angular momenta at high magnetic fields and is capable of continuously slowing and compressing the 1D velocity distribution. Detailed Monte-Carlo simulations show a significant increase in flux of slow molecules compared to current slowing techniques. To underline our theoretical efforts, we perform an experiment on an atomic test bed with similar level structure, showing good agreement between experimental and theoretical results. The advantages and implementation of our scheme closely resemble those of atomic Zeeman slowing, and implementation of our idea in a molecular system could be the missing link for realizing a large, ultra-cold ensemble of directly cooled molecules.
