Phys. Rev. D 53, 5382–5393 (1996)Bimodal coherence in dense self-interacting neutrino gasesReceived 17 July 1995; published in the issue dated 15 May 1996 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. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
