Welcome to the Molecular Quantum Optics & Quantum Nanophysics Group

Our research is focused on:

  • Universal matter-wave interferometry:
    We are working on scalable concepts and universal beam splitters for quantum experiments with atoms, atomic and molecular clusters, tailored organic molecules, native biomolecules and nanoparticles.
  • Quantum physics at the interface to the classical world:
    We explore the mass and complexit limits of matter-wave interference, experimental quantum decoherence and interferometric tests of wave function collapse
  • Quantum physics at the  interface to chemistry:
    We use matter-wave interference fringes as quantum nanorulers to measure electric, magnetic, optical and structural and dynamic properties of delocalized molecules.
  • Quantum physics at the  interface to biology:
    We realize matter-wave experiments with vitamins, antibiotics and polypeptides. For that purpose, we develop new beam and detection techniques for biomolecules.
  • Quantum physics at the  interface to mass spectrometry technologies:
    We study superconducting nanowire detectors for biomolecular beams, ultra-fast optical methods to prepare mass and charge controlled biomolecular beams for advanced mass and optical spectroscop as well as quantum experiments.
  • Quantum physics at the interface to optomechanics:
    We exploit optical forces to achieve optical cooling of dielectric nanospheres in high-finesse microcavities as well as rotational cooling of dielectric nanorods to enable high-mass quantum experiments.
