Fast Neutrino Flavor Conversion: Collective Motion vs. Decoherence
Francesco Capozzi, Georg Raffelt, Tobias Stirner
In an interacting neutrino gas, flavor coherence becomes dynamical and can propagate as a collective mode. In particular, tachyonic instabilities can appear, leading to "fast flavo…

Normal-mode Analysis for Collective Neutrino Oscillations
Sagar Airen, Francesco Capozzi, Sovan Chakraborty +3
In an interacting neutrino gas, collective modes of flavor coherence emerge that can be propagating or unstable. We derive the general dispersion relation in the linear regime that…

Liouville term for neutrinos: Flavor structure and wave interpretation
Tobias Stirner, Günter Sigl, Georg Raffelt
Neutrino production, absorption, transport, and flavor evolution in astrophysical environments is described by a kinetic equation .…
