当中微子-反中微子不对称性存在时，得到了描述中微子振荡的非线性方程的解析解。如果中微子的化学势不为零，那么在早期宇宙中就会出现这样的系统。方程的解导致由两种模式支配的新型相干行为。这些双峰解提供了对早期宇宙中稠密中微子气体和中微子振荡的新见解，从而使人们能够用非零化学势来观察中微子的味道行为。美国物理学会（American Physical Society）
Analytical solutions are obtained to the nonlinear equations describing neutrino oscillations when explicit neutrino-antineutrino asymmetries are present. Such a system occurs in the early Universe if neutrinos have a nonzero chemical potential. Solutions to the equations lead to a new type of coherent behavior governed by two modes. These bimodal solutions provide new insight into dense neutrino gases and into neutrino oscillations in the early Universe, thereby allowing one to surmise the flavor behavior of neutrinos with a nonzero chemical potential. {copyright} {ital 1996 The American Physical Society.}
