  Cold Clusters in Deep UV Light Fields for Quantum Interferometry

  We are setting up a new beam line for cold metal clusters, aiming at quantum states of particles the mass range up to 1 MDa. This combines the latest advances in cluster science, deep ultra-violet laser physics, mass spectroscopy, matter-wave technologies and quantum optics.

  LUMI Cluster Interferometry

  Quantum interferometry with large metal clusters promises to push the boundaries between quantum experiments and classical phenomena. Long coherence times, large beam separations and high masses will provide an unprecedented sensitivity to still hypothetical non-standard phenomena in physics, while at the same time offering a specific and highly sensitive tool to measure tiny forces.    

  Slow Proteins

  Advances in biomolecular quantum optics and analysis will profit from slow and cold proteins. If you are interested in working at the interface between the life sciences, laser physics, quantum optics and mass spectrometry, please contact us for more details.  

  Tools for Protein Interferometry

  Our group has pioneered universal interferometry, from atoms over fullerenes and hydrocarbons to vitamins, polypeptides and tailored macromolecules. We are advancing on this path to develop tools for the coherent manipulation of genuine biomolecules in the gas phase, aiming here at quantum interference of proteins.  

  Cooling of Non-Spherical Nanoparticles

  We are preparing, exploring and utilizing rotational quantum states of trapped dielectric nanorods. This work at the interface between optomechanics and quantum interferometry shall enable new tests of quantum linearity and advanced quantum sensing applications.
