Description

We present the novel Long-Baseline Universal Matter-wave Interferometer (LUMI) in Vienna, a near-field, Kapitza-Dirac-Talbot-Lau type interferometer designed for quantum interference of high-mass molecules. It improves on an earlier Kapitza-Dirac-Talbot-Lau interferometer [1] by a factor of 10 in length and a factor 100 in inertial force sensitivity.
The modular design of the experiment permits the in-vacuum exchange between optical and material diffraction gratings as well as the introduction of electric and magnetic fields, collision cells or spectroscopy lasers to explore the electronic, optical, magnetic and structural properties of a very diverse class of particles. We discuss new experiments with atoms, complex molecules and future prospects for high-mass clusters with improved precision over previous devices.
