GRAvity, Spectroscopy and Interferometry with ultra-cold Atoms and Neutrons

In the GRASIAN collaboration we pursue research with the lightest neutral particles/atoms at lowest kinetic energies, nearly at rest. Subject of our work are hydrogen and antihydrogen, neutrons, muonium and positronium. Their quantum properties in the field of gravity, Casimir-Polder and Van-der-Waals potentials, precise optical and microwave spectroscopy are in the focus of our collaboration.
