Neutrino flavor-wave transport: Numerical tests and theoretical challenges
Anson Kost, Lucas Johns, Huaiyu Duan
Neutrino quantum kinetics is computationally intractable in the neutrino-dense arenas of core-collapse supernovae and neutron star mergers. Flavor-wave (or flavomon) transport is a…

Landau Damping of Collective Neutrino Oscillation Waves
Anson Kost, Huaiyu Duan
Dense neutrino media in core-collapse supernovae and neutron star mergers can experience collective flavor transformations in the form of neutrino oscillation waves. It was recentl…

Once-in-a-lifetime encounter models for neutrino media II: Quasi-steady states and miscidynamic flavor evolution
Anson Kost, Lucas Johns, Huaiyu Duan
We extended the once-in-a-lifetime encounter (OILE) model to stochastic interactions among neutrinos. As in the original OILE model, the new model reproduces the mean-field behavio…
