Oscillation Induced Neutrino Asymmetry Growth in the Early Universe
Kimmo Kainulainen, Antti Sorri
We study the dynamics of active-sterile neutrino oscillations in the early universe using full momentum-dependent quantum-kinetic equations. These equations are too complicated to…
Creation of large spatial fluctuations in neutrino asymmetry by neutrino oscillations
Kari Enqvist, Kimmo Kainulainen, Antti Sorri
We consider active-sterile neutrino oscillations in the early universe in an inhomogeneous isocurvature background. We show that very small initial baryonic seed-inhomogeneities ca…
Physical origin of "chaoticity" of neutrino asymmetry
Antti Sorri
We consider the indeterminacy in the sign of the neutrino asymmetry generated by active-sterile neutrino oscillations in the early universe. The dynamics of asymmetry growth is dis…
On chaoticity of the amplification of the neutrino asymmetry in the early universe
Kari Enqvist, Kimmo Kainulainen, Antti Sorri
We consider numerically the growth of neutrino asymmetry in active-sterile neutrino oscillations in the early universe. It is shown that the final sign of the asymmetry can be high…
