TL;DR: In this paper, a unified theory of ion holes and electron-acoustic vortices is presented, coupled with the hydrodynamic equations for electrons via the Poisson equation, and a novel type of nonlinear structures is found, which has the form of a quasi two-dimensional density rarefaction that is spatially localized by the ion trapping in the negative potential.

TL;DR: In this paper, it was shown that an electrostatic pump near the upper hybrid resonance frequency can induce a new macroscopic parametric instability, which could be one of the candidates for the excitation of the low-frequency drift wave type fluctuations at the plasmapause.

TL;DR: A nonlinear Schrodinger equation for the propagation of a dust-lattice wave in a one-dimensional chain of a plasma crystal is derived by using the Krylov-Bogoliubov-Mitropolsky (KBM) perturbation technique.

TL;DR: In this article, a correspondence between the family of cylindrical nonlinear Schrodinger (cNLS) equations and the one of Cylindrical Korteweg-de Vries (cKdV) equations is constructed.

TL;DR: In this article, the plasma particle heating based on the kinetic theory of wave-particle interactions involving kinetic Alfven waves and lower-hybrid drift modes is presented, where the collisionless solar corona is ideal for supporting kinetic wave-plasma interactions.
