Many-body effects of collective neutrino oscillations
arXiv:2111.00437 · doi:10.1103/PhysRevD.105.103002
Abstract
Collective neutrino oscillations are critical to determine the neutrino flavor content, which has striking impacts on core-collapse supernovae or compact binary merger remnants. It is a challenging many-body problem that so far has been mainly studied at the mean-field approximation. We use a setup that captures the relevant physics and allows exact solution for a large number of neutrinos. We, for the first time, find quantitative deviation from the mean-field evolution due to many-body decoherence in flavor space. Similar features have been observed in a spin-1 Bose-Einstein condensate, which opens the possibility of experimental explorations of collective flavor phenomena. Our results call for more careful examinations on the possible many-body corrections to collective neutrino oscillations in astrophysical environments.
