DESCRIPTION:In the early universe or in some regions of supernovae\, the n
 eutrino refractive index is dominated by the neutrinos themselves. Several
  previous studies have found numerically that these self-interactions have
  the effect of coupling different neutrino modes in such a way as to synch
 ronize the flavor oscillations which otherwise would depend on the energy 
 of a given mode. We show a simple explanation for this baffling phenomenon
  in analogy to a system of magnetic dipoles which are coupled by their sel
 f-interactions to form one large magnetic dipole which then precesses cohe
 rently in a weak external magnetic field (analogous to the weak-field Zeem
 an effect in atoms).\n\nhttps://indico.ific.uv.es/event/1266/
