Testing common approximations of neutrino fast flavor conversion

Erick Urquilla, Lucas Johns

Common approximations for neutrino fast flavor conversion are limited by discretizing continuous evolution, assuming spatial homogeneity, and requiring accompanying instability.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The approximations of FFC that have been implemented so far are limited by at least two of three factors: (1) approximating continuous evolution as a discrete sequence of instabilities, (2) using spatially homogeneous asymptotic states, and (3) assuming that FFC must be accompanied by instability.

C2weakest assumption

That the numerical experiments performed in this study sufficiently represent the physical regimes and continuous evolution relevant to FFC in supernovae and mergers to identify the primary limiting factors in existing approximations.

C3one line summary

Numerical experiments reveal that common approximations for neutrino fast flavor conversion are limited by discrete instability sequences, spatially homogeneous asymptotic states, and the assumption that conversion requires instability.
