News Molecular Quantum Gases The POLAR experiment found the ground state of bosonic NaK ! In recent experimental efforts, the ultracold Na+K team performed photoassociation of their ultracold samples to the excited state manifold converging to the Na(3s) + K(4p) asymptote. Having ... Torben defended his thesis! Congratulations! Zeeman slower paper published An efficient radiative slowing scheme for molecules. Paper published! Feshbach spectroscopy and dual-species Bose-Einstein condensation of Na - K mixtures PhD positions available Experiments with ultracold NaK dipolar molecules First double BECs. Both, 23Na and 39K are condensed at the same spot at the same time. New PhD student! Philipp joined our team. Welcome! First Na-K Feshbach Spectroscopy We managed to get nice signals both on 23Na and 39K in the optical dipole trap and saw first losses due to three body interactions. First Na BEC We managed to load sodium atoms to the crossed optical dipole trap and evaporate them. We end up with a nice bimodal distribution. Paper published! Our electrode paper is on arXiv and got accepted for publication. Matthias defended his thesis! Congratulations! Vacuum Chamber Finally! After a long struggle, we finally got rid of our weird vacuum problems! Now, the lifetime of the atomic ensembles is no longer degrading over a period of several months – but stable in the ... Paper published! Our paper on the reaction kinetics of chemical processes occurring in the ultracold regime has been published. Paper published! Our paper on the modelling and the experimental demonstration of a two-photon coherent transfer path from ultracold Na and K atoms to ultracold ground state molecules has been published. Finally, we can move into our labs!
