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.
