One-Dimensional Nonlinear and Nonlocal Oscillations of Plasma in Solid Body
A simple one-dimensional model describing nonlinear and nonlocal oscillations of electron plasma is considered. Due to regard of the nonlocality of the field potential, it allows one to smooth down the peaks of nonlinear waves, to steep up the wave front, and to modify the velocity amplitude and phase of the traveling wave.
