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…

Dispersion Relations of Collective Flavor Excitations in Dense Neutrino Media
Anson Kost, Huaiyu Duan
We apply the Landau damping theory to collective flavor excitations in dense neutrino media. We demonstrate explicitly that the (meta-)stable modes of the collective flavor excitat…

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…
