Self-consistency in models of neutrino scattering and fast flavor conversion
Lucas Johns, Hiroki Nagakura
Several recent numerical studies have examined the effects of neutrino neutral-current scattering on fast flavor conversion (FFC). Those studies are in apparent conflict, with some…
Fast flavor instabilities and the search for neutrino angular crossings
Lucas Johns, Hiroki Nagakura
With the recognition that fast flavor instabilities likely affect supernova and neutron-star-merger neutrinos, using simulation data to pin down when and where the instabilities oc…
Fast oscillations, collisionless relaxation, and spurious evolution of supernova neutrino flavor
Lucas Johns, Hiroki Nagakura, George M. Fuller +1
Mounting evidence indicates that neutrinos likely undergo fast flavor conversion (FFC) in at least some core-collapse supernovae. Outcomes of FFC, however, remain highly uncertain.…
Neutrino oscillations in supernovae: angular moments and fast instabilities
Lucas Johns, Hiroki Nagakura, George M. Fuller +1
Recent theoretical work indicates that the neutrino radiation in core-collapse supernovae may be susceptible to flavor instabilities that set in far behind the shock, grow extremel…
