We are fascinated by these research fields

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 complexity limits of matter-wave interference, experimental quantum decoherence and interferometric tests of wave function collapse.
Cluster physics for matter-wave interferometry:
We are exploring advanced cluster sources and DUV laser technologies for high-mass interferometry.
Quantum measurements for physical chemistry:
We use matter-wave interference fringes as quantum nanorulers to measure electric, magnetic, optical and structural and dynamic properties of delocalized molecules.
Quantum tools for biomolecular physics:
We have realized matter-wave experiments with vitamins, antibiotics and polypeptides. For that purpose, we have developped ultra-fast biomolecular launch techniques.
Optomechanics for high-mass matter-wave interferometry:
We exploit optical forces to achieve optical cooling of dielectric nanoparticles in high-finesse cavities to enable novel high-mass quantum experiments.
Quantum sensors for mass spectrometry:
We are exploring superconducting nanowire detectors as in advanced mass spectroscopy
Single-photon charge control:
We are exploring new avenues towards biomolecular beams with high control over their charge and motional state for new experiments in protein quantum optics.
