Microwave manipulation of neutral polar molecules — •Simon Merz1,2, Nicolas Vanhaecke3, Gerard Meijer3, and Melanie Schnell1,21Center for Free-Electron Laser Science, 22607 Hamburg — 2Max-Planck-Institut für Kernphysik, 69117 Heidelberg — 3Fritz-Haber-Institut der Max-Planck-Gesellschaft, 14195 Berlin

An important remaining challenge in the field of cold molecules is a general technique to manipulate the motion of polar molecules in high-field-seeking states. This is a crucial step towards control of cold molecules in their ground states and of all large and more complex molecules. As an interesting alternative to the already demonstrated and experimentally rather demanding alternating gradient methods, we use the interaction of polar molecules with near resonant microwave radiation.

Here, we present the latest results of our microwave decelerator [1], and we will show full control over the longitudinal phase space distribution of a slow packet of ammonia molecules. Furthermore, the next steps towards efficient microwave trapping will be discussed.
