Collaborations and Links


  • Interferometry and Suprafluid Helium Gyroscope:
    This is a link to the group of F.Hasselbach in Tübingen. This group has done a lot of fascinating experiments in electron interferometry. At their institute G.Möllenstedt and H.Düker invented the biprism interferometer for electrons in 1955. This was the first well working two-path interferometer for massive particles ever. When we started to build up an interferometer without any experience in this field, the friendly assistence of F.Hasselbach and U.Maier was very helpful.
  • Quantum Optics and Foundations of Physics
    The group of Prof. A.Zeilinger in Innsbruck has many different areas of interest among which the interferometry with atoms and neutrons is closely related to our field of activity.
    • Experimental test of the foundations of physics;
    • Complementarity in quantum physics, which includes the wave-particle duality and the Heisenberg uncertainty relations;
    • Einstein-Podolsky-Rosen correlations;
    • Bell inequality experiments studying nonlocality of quantum measurements;
    • Experimental tests of the contextuality of quantum measurements, i.e. even commuting observables will show different measurement results depending on the context of measurement;
    • The manipulation of single quantum entities, single or photon pair effects, single atom and neutron interferometry;
    • Gravitational and inertial effects in quantum systems;
    • Quantum information processing, quantum cryptography, and quantum computation.
  • Karl Svozil
    Karl Svozil is a colleague of J.Summhammer and G.Krenn working at the Institute of Theoretical Physics of the TU-Wien (Vienna).     His major interests are:
    • Quantum information and computation theory
    • Automaton logic --- deterministic modelling of complementarity
    • Applications of the theory of recursive (computable) functions to physics
    • Physical undecidability by diagonalization
    • Intrinsic (Endo-) physics
    • Signalling by stochastic fractal coding (stochastic interference)

In regular meetings which, corresponding to local tradition, take place in a coffee house various topics concerning relativity, complementarity and foundations of physics are discussed.
