Testing Foundations of Quantum Mechanics at Different Energy Scales. Teil 6B: Nikolaos Mavromatos (2)
Description (de)
Workshop in Honour of Reinhold A. Bertlmann Mitschnitt einer Veranstaltung der Fakultät für Physik der Universität Wien am Sonntag, dem 27. Juni 2010 im Seminar-Hotel Schneeberghof in Puchberg am Schneeberg Teil 6B: Nikolaos Mavromatos: Quantum Gravity and Entangled Particle States (zweiter Teil) Moderation: Beatrix Hiesmayr Some Quantum Gravity models entail a foamy structure for space time at microscopic (Planck-)scales. Matter in such backgrounds may experience quantum decoherence, as a result of information being carried out by gravitational degrees of freedom, not accessible by local scattering experiments. Concrete examples of such models may be provided by string theory with space-time membrane defects. In all such models, the quantum CPT operator of the effective field theory of the low-energy degrees of freedom may be "pertubatively ill-defined" leading to modifications in the Einstein-Podolsky-Rosen (EPR) correlators in entangled particle states. These may be falsifiable in future upgraded facilities of neutral mesons, for instance a possible upgrade of DaFNE detector or B-mesons. Complementary tests / bounds of such a decoherence may also be provided by cosmic neutrino and high-energy photon astronomies.
