Gravitationally induced Decoherence in Neutrino Oscillations: Bridging between Phenomenological and Microscopic Models — Alba Domi1, João Coelho3, Kristina Giesel1, Max Joseph Fahn2, Renata Ferrero1, and •Roman Kemper1 — 1Friedrich-Alexander Universität Erlangen-Nürnberg, Germany — 2Università di Bologna, Italy — 3APC, Paris
In this talk, the role of gravitationally induced decoherence in open quantum systems is discussed in the context of neutrino oscillations. Often in phenomenological models, the decoherence parameters appear as free parameters encoded in a vectorised dissipator. The properties of a class of such dissipators are examined. Possible links to underlying gravitational microscopic models are discussed, which can provide a physical interpretation of the involved decoherence parameters. In addition, it is considered how different physical assumptions entering the decoherence model are reflected in the resulting neutrino oscillation probabilities.
