A theoretical study is presented for the propagation of Dust Ion Acoustic Waves in an unmagnetized four-component plasma, consisting Maxwellian negative ions, cold mobile positive $\kappa$-distributed electrons and positively charged dust grains. Based on characteristics Sagdeev pseudopotential phase portraits, three types nonlinear waves are observed --- solitons, double layers supersolitons. ...

In the analysis of nonlinear waves in plasma, especially for search periodic waves, shock and solitons, mechanical analogy methods are widely applicable. The most famous them is Sagdeev pseudopotential method. However, sometimes mathematical difficulties arise when deriving formulas pseudopotentials. author proposes three tricks to get around these obtain exact pseudopotentials cases where dire...

Recently, strong effort has been done in exploring shock acceleration for the generation of highly energetic ion beams, with applications e.g. for medical purposes. The heating of a near-critical density plasma target with a laser, increases the electron temperature and excites ion acoustic waves, which can lead to electrostatic shock formation due to non-linear wave breaking. The higher inerti...

Large-amplitude electrostatic waves propagating parallel to the background magnetic field have been observed at Earth’s magnetopause by Magnetospheric Multiscale (MMS) spacecraft. These are in region where there is an intermixing of magnetosheath and magnetospheric plasmas. The plasma modeled as a five-component consisting three types electrons, namely, two counterstreaming hot electron beams c...

2014 In this article we derive an alternative to the classical quasi-linear method to describe the evolution of the averaged distribution function avoiding the difficulties associated to the resolution of a three dimensional diffusion equation. We consider explicitly the case of the electron species in presence of a current-driven ion-acoustic turbulence. Our formulation aims to confirm the arg...

Supersolitons are a recent addition to the literature on large-amplitude solitary waves in multispecies plasmas. They are distinguished from the usual solitons by their associated electric field profiles which are inherently distinct from traditional bipolar structures. In this paper, dust-ion-acoustic modes in a dusty plasma with stationary negative dust, cold fluid protons, and nonthermal ele...
