When the neutral current neutrino-neutrino interaction is treated completely, rather than as an interaction among angle-averaged distributions, or as a set of flavor-diagonal effective potentials, the result can be flavor mixing at a speed orders of magnitude faster than that one would anticipate from the measured neutrino oscillation parameters. It is possible that the energy spectra of the three active species of neutrinos emerging from a supernova are nearly identical.

• Self-induced neutrino flavor conversion without flavor mixing (2016, background): “We study a new item on this list which has eluded most workers in this field with the notable exception of Ray Sawyer [5, 6], i.e., the surprising insight that collective flavor conversion need not depend on neutrino mixing parameters.”
• Collective neutrino flavor conversion: Recent developments (2016, background): “While this phenomenon had been noted a long time ago [9], its significance had eluded much of the community.”
• What can be learned from a future supernova neutrino detection (2017, background): “crossings’ - the electron lepton number current changes sign as a function of angle relative to the radial direction - and, using stability analysis, such crossings are expected to lead to new flavor transformation effects [288, 289, 290, 291].”
• Collective neutrino flavor transitions in supernovae and the role of trajectory averaging (2007, background): “The interest of such effects for the neutrino flavor evolution in the dense SN core has long been recognized [35–39].”
