Self-Maintained Coherent Oscillations in Dense Neutrino Gases
arXiv:hep-ph/9506262 · doi:10.1103/PhysRevD.52.621
Abstract
We present analytical solutions to the nonlinear equations describing the behavior of a gas of neutrinos with two flavors. Self-maintained coherent flavor oscillations are shown to occur when the gas density exceeds a critical value determined by the neutrino masses and the mean neutrino energy in the gas. Similar oscillations may have occurred in the early Universe.
