Fast flavor conversions of supernova neutrinos: Classifying instabilities via dispersion relations
Fast flavor conversions of supernova neutrinos: Classifying instabilities via dispersion relations
Supernova neutrinos can exhibit a rich variety of flavor conversion mechanisms. In particular, they can experience ``fast'' self-induced flavor conversions almost immediately above the core. Very recently, a novel method has been proposed to investigate these phenomena, in terms of the dispersion relation for the complex frequency and wave number …
