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…
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…
Local-equilibrium theory of neutrino oscillations
Lucas Johns, Anson Kost
Miscidynamics describes coarse-grained neutrino transport under the assumption that flavor mixing is in local equilibrium. Here we introduce the concept of turbulent flavor-wave vi…
Once-in-a-lifetime encounter models for neutrino media: From coherent oscillations to flavor equilibration
Anson Kost, Lucas Johns, Huaiyu Duan
Collective neutrino oscillations are typically studied using the lowest-order quantum kinetic equation, also known as the mean-field approximation. However, some recent quantum man…
Collisional flavor pendula and neutrino quantum thermodynamics
Lucas Johns, Santiago Rodriguez
Neutrinos in core-collapse supernovae and neutron-star mergers are susceptible to flavor instabilities of three kinds: slow, fast, and collisional. Prior work has established mappi…
