Quantum Nanophysics & Molecular Quantum Optics

  • We are exploring new ways to harness quantum phenomena with biomolecules,  clusters & nanoparticles in a complexity range that has not been accessible, hitherto. 
  • We are developping methods to prepare, cool & detect molecular beams of neutral biomolecules & nanomaterials.
  • We are exploring nanomechanical & optical matter-wave beam splitters for objects in this entire complexity range and we have combined them into a set of unique matter-wave interferometers.
  • Our new quantum-interference technologies are promising for interference-assisted molecule metrology, where we use miniscule matter-wave fringe shifts as a measure for electrical/optical/magnetic/structural properties of molecules in external fields.
  • We are advancing cavity cooling of dielectric nanoparticles, aiming at novel tests of the linearity of quantum mechanics in an unprecedented mass range.
