    Neutron Matter Wave Quantum Optics.Helmut Rauch - 2012 - Foundations of Physics 42 (6):760-777.
    Neutron matter-wave optics provides the basis for new quantum experiments and a step towards applications of quantum phenomena. Most experiments have been performed with a perfect crystal neutron interferometer where widely separated coherent beams can be manipulated individually. Various geometric phases have been measured and their robustness against fluctuation effects has been proven, which may become a useful property for advanced quantum communication. Quantum contextuality for single particle systems shows that quantum correlations are to some extent more demanding than classical (...)

    The Wave-Particle Dualism in 1992: A Summary. [REVIEW]Marie-Christine Combourieu & Helmut Rauch - 1992 - Foundations of Physics 22 (12):1403-1434.
    We review the past and present theoretical and experimental situations relating to wave-particle dualism. New tests aimed at enlightening the individual behavior as awave, then as aparticle, of asingle quantum mechanical system in the same experimental run are presented. The related epistemological, philosophical, and historical backgrounds are presented in a twofold exposition taking into account thepositivistic standard Copenhagen interpretation as well as therealist de Broglian point of view.

    Quantum Physics with Neutrons: From Spinor Symmetry to Kochen-Specker Phenomena. [REVIEW]Helmut Rauch - 2012 - Foundations of Physics 42 (1):153-172.
    In 1974 perfect crystal interferometry has been developed and immediately afterwards the 4π-symmetry of spinor wave-functions has been verified. The new method opened a new access to the observation of intrinsic quantum phenomena. Spin-superposition, quantum state reconstruction and quantum beat effects are examples of such investigations. In this connection efforts have been made to separate and measure various dynamical and geometrical phases. Non-cyclic and non-adiabatic topological phases have been identified and their stability against various fluctuations and dissipative forces has been (...)

    Epistemological and Experimental Perspectives on Quantum Physics.Abner Shimony, Helmut Rauch, Giancarlo Ghirardi, Catherine Chevalley, Jean-Marc Lévy-Leblond & Yuri F. Orlov - 1999 - Springer Verlag.
    The Society for the Advancement of the Scientific World Conception has done me a great honor by inviting me to be the Sixth Vienna Circle Lecturer. The invitation has also stirred some deep emotions. A central figure of the Vienna Circle, Rudolf Carnap, was my revered teacher of philosophy at the University of Chicago in 1948–9 and later an informal adviser when I wrote a doctoral thesis at Yale University on inductive logic, and he was a friend during those years (...)
