TL;DR: In this paper, large-amplitude Alfven waves propagating along the guide magnetic field in a three-component plasma are shown to be spatially localized due to their nonlinear interaction with nonresonant electrostatic density fluctuations.

TL;DR: In this paper, it was shown that an accelerated electron can emit unstable electromagnetic waves which propagate along the guide magnetic field, which can be used to generate right-handed circularly polarized whistler waves.

TL;DR: In this paper, the dynamics of large localized repulsive clouds are examined by means of exact non-stationary solutions of the one-dimensional Thomas-Fermi model, showing the nonlinear flattening of the cloud peak, the wave breakdown at the cloud peripheries, and the condensate velocity distributions.

TL;DR: In this paper, the reduced magnetohydrodynamic equations governing low-frequency electromagnetic turbulence are derived taking into account the compressional and sheared magnetic field perturbations in high-beta magnetoplasmas.

TL;DR: In this paper, the potential distribution of uniformly drifting colloidal ions was investigated using a test particle approach and appropriate dielectric-response function for an n-type piezoelectric semiconductor plasma, and the dynamical oscillatory wake potential, besides the usual static Coulombian Debye-Huckel potential, was found to contribute more dominantly due to the plasma effect, rather than due to electron-phonon coupling interactions.
