“…4 -12 Specifically, it has been recognized that intense neutrinos interact with the background plasma electrons due to the driving force of the neutrinos. Thus, strong electric fields and plasma waves 4,7,8,10,11 are produced on account of the charge separation in dense plasmas. Neutrino driven plasma waves ͑Langmuir and ion-sound waves͒ undergo Landau damping, thereby reducing the neutrino energies, and allowing the neutrinos to escape more easily from the core of the supernova.…”

The nonlinear interaction between intense neutrino beams and sound waves in dense plasmas is considered. Accordingly, a Schrödinger-type equation is derived for the amplitude wave function of neutrinos interacting with a background plasma via the weak Fermi force. The neutrino driving (ponderomotive) force pushes the plasma electrons locally, thereby creating space charge electric fields through which the inertial ions are reinforced. It is shown that the nonlinearly coupled neutrinos and the ion sound perturbations are responsible for the formation of stationary envelope solitons and nonstationary shocks. The relevance of these nonlinear structures to supernova explosions is pointed out.
