TL;DR

This paper explores subtle aspects of neutrino oscillations, including coherence, entanglement, and potential influences from cosmic structures and dark matter, using space-time localization diagrams to analyze these phenomena.

Contribution

It introduces a novel approach using localization diagrams to analyze neutrino oscillations and discusses effects of cosmic structures and dark matter on oscillation behavior.

Findings

Decoherence effects are negligible for reactor and source neutrinos.

Space-time localization diagrams reveal coherence and entanglement in neutrino oscillations.

Potential influence of cosmic strings and dark matter on neutrino behavior is discussed.

Abstract

Space-time localization diagrams ``unlock" subtle aspects of $\nu$ oscillations such as coherence and entanglement. Observability of propagation decoherence in oscillating neutrino state is discussed. The sizes of WPs of reactor and source neutrinos are estimated and it is shown that damping effect due to decoherence is negligible. Among topics of interest are transition from microscopic to macroscopic description of matter effects, oscillations in non-linear generalization of Quantum Mechanics, influence of complex structure of vacuum, in particular, possible presence of cosmic strings and domain walls on oscillations, neutrino oscillations driven by the effective neutrino masses generated via refraction on very light dark matter particles.
