Abstract
Analytical models for weakly nonlinear electron plasma waves are considered in order to obtain dynamic equations for the space-time evolution of their local power spectra. The model contains the wave kinetic equation as a limiting case for slow, long wavelength modulations. It is demonstrated that a finite spectral width in wavenumbers has a stabilizing effect on the modulational instability. The results invite a simple heuristic relation between the spectral width and the root-mean-square amplitude of stable stationary turbulent Langmuir wave spectra. A non-local average dispersion relation is derived as a limiting form by using the formalism developed for the spectral dynamics.

Langmuir wave electric fields induced by electron beams in the heliosphere

TL;DR: In this article, the authors investigate how solar wind density turbulence changes the probability distribution functions, mean value and variance of the beam-driven electric field distributions, and demonstrate how the properties of the electric field distribution should vary radially from the Sun to the Earth and provide a numerical prediction for the upcoming Solar Orbiter and Solar Probe Plus spacecraft.

On the Quantum Correction for Thermodynamic Equilibrium

TL;DR: In this paper, it was shown that instead of Wigner's approximation, instead of the classical potential U in the exponent by U-kTf, where f is the same as Wigneer's function, the probability of any configurational position is then proportional to exp −U/kT, with U the potential energy.

Exact Nonlinear Plasma Oscillations

TL;DR: In this paper, it is shown that, by adding appropriate numbers of particles trapped in the potential energy troughs, essentially arbitrary traveling wave solutions can be constructed, and the possible existence of such waves in an actual plasma will depend on factors ignored in this paper, as in most previous works, namely interparticle collisions and the stability of the solutions against various types of perturbations.
