Parametric Resonance Amplification of Neutrino Oscillations in Electromagnetic Wave with Varying Amplitude and "Castle Wall" Magnetic Field

Abstract

Within the Lorentz invariant formalizm for description of neutrino evolution in electromagnetic fields and matter we consider neutrino spin oscillations in the electromagnetic wave with varying amplitude and in "castle wall" magnetic field. It is shown for the first time that the parametric resonances of neutrino oscillations in such systems can occur.
