Perfect crystal neutron optics

Objective



Advanced neutron instrumentation is essential for the competitiveness of Neutron physics is usually performed in small groups and is mainly neutron scattering techniques for condensed matter research. Perfect University-based research utilizing central facilities for experimental crystal optics provide the most important contribution to this topic work. Therefore, students, graduates and post-docs are involved in all because coherent beam handling can open up new possibilities and several groups as well as engineers and technicians. They become educated in advanced instrumentation techniques, neutron applications in condensed further breakthroughs can be anticipated when optical methods are able to be adapted to neutrons. The network will progress research and the matter research and in international cooperation work.

The scope of development of new methods in the following areas: a) Perfect crystal research spans from fundamental quantum physics aspects via advanced measurement techniques and the technology of advanced crystal growth. small-angle scattering cameras (P. Mikula/Rez, H. Rauch/Wien, D. Schwahn/Julich, C. Zeyen/ Grenoble, F. Mezei, A. Ioffe/Berlin) b) Gradient and multiple crystals (B. Alefeld/Julich, W. Treimer/Berlin, L. Rosta/Budapest, Magerl/Grenoble) c) Neutron interferometers (U. Bonse/Dortmund, H. Rauch/Wien, A. Ioffe/Berlin, P. Boni, A. Furrer/Villigen, L. Rosta/Budapest) d) Crystal resonators (C. Carlile/Rutherford, H. Rauch/Wien) e) Vibrating crystals (P. Mikula/Rez, J. Kulda/Grenoble) f) Bragg focusing and wave propagation in crystals (P. Mikula/Rez, A. Zeilinger/Innsbruck) g) Quantum physics consequences (S. Pascazio/Bari, J. Perina, Z. Hradil/Olomouc) h) Crystal characterization, fabrication and testing (W. Zulehner/Burghausen, E. Seidl/Wien, U. Bonse/Dortmund) i) Phase space manipulation (B. Alefeld/Julich, H. Rauch/Wien) Besides the development and improvement of methods, perfect crystal optics will be used to establish neutron quantum optics.

Coherence properties of neutron beams, the development of neutron resonators and possibly of novel types of interferometers, as well as contributions to the foundation of quantum mechanics will be investigated within this network also. Methods of quantum optics will be applied to describe the statistical and coherence properties of neutron beams. Special attention will be devoted to the quantum limits and to possible nonclassical behaviour, such as momentum squeezing, sub-Poissonian behaviour and evidence for Schrodinger cat-like states. The investigation and interpretation of these effects will contribute to a deeper understanding of quantum mechanics. Cooperation with an industrial partner is an integral part of the network.
