“…Attributable to their event in different physical environments, going from astrophysical plasmas (see [22,23] and references therein) and fluids [24] to semiconductors [25][26][27][28][29] and nonlinear optics [30][31][32], solitons have proved to be beneficial items for scientific examination. Moreover, they can be generated in laboratories, for example, in double-plasma devices [33,34] and nonlinear transmission lines [35]. Washimi and Taniuti [36] were the pioneers who investigated the propagation of electrostatic solitary waves in plasmas by deriving the Korteweg-de Vries (KdV) equation [37] for ion-acoustic waves in a nonlinear system using the notable reductive perturbation technique [38,39].…”

The capacitively coupled plasma is investigated kinetically utilizing the particle- in-cell technique. The Argon (Ar) plasma is generated via two radio-frequencies. The plasma bulk density increases by increasing the voltage amplitude of the high frequency (≥ 13.56 MHz) which is much greater than the ion plasma frequency. The intermediate radio-frequencies ( ≈ 1 MHz) which are comparable to the ion plasma frequency causes a broadening of the ion energy distribution considerably, i.e., ions gain energies above and lower than the time-averaged energy. The good agreement between published experimental results and our theoretical calculations via the Ensemble- in-Spacetime model confirms the modulation of ions around time-averaged values. Intermediate frequencies allow ions to respond partially to the instantaneous electric field. The response of ions to the instantaneous electric field is investigated semi- analytically. The dispersion relation of the plasma sheath and bulk are derived. Stable ion acoustic modes are found. The ion-acoustic modes have two different velocities and carry energy from the sheath edge to the electrode. Also, intermediate frequencies excite solitons in the plasma sheath; the results may help to explain the ion density, flux, and energy modulation, and, consequently, the broadening of the ion energy distribution.

“…Likewise, collisional effects and other damping mechanisms can be effectively controlled by varying the plasma parameters, ensuring that the solitons have a long lifetime. Consequently, KdV solitons and other similar 1D solitons have been experimentally studied by many researchers (for a detailed review see [13]) ever since the first laboratory observations of Ikezi et al [14]. More recently, such pulses were also observed in dusty plasmas [12].…”

Observation of sharply peaked solitons in dusty plasma simulations

We report on observations of cusp-like sharply peaked dust acoustic solitons in a one-dimensional fluid simulation of a dusty plasma system. These nonlinear singular structures, dithering at the wave breaking point, are found to be long-lived entities that emerge spontaneously from a variety of largeamplitude initial perturbations. Such excitations can play a significant role in wave breaking and wave-particle dynamics in dusty plasmas and may explain some recent experimental observations. Contents

Ion-acoustic solitary waves in ion-beam plasma with Boltzmann electrons

et al. 2012

Particle simulations and a pseudopotential method were used to study ion-acoustic solitary waves in a plasma composed of Boltzmann electrons and kinetic beam ions. Pseudopotential theory was first applied to determine how ion-acoustic solitary waves can exist in a two-component plasma. Then, particle simulations were carried out, wherein ion-acoustic solitary waves were excited by modulating the bias grid voltage in a double plasma model. For the modulation, the potential of the grid bias was rapidly decreased, such that hump-type ion-acoustic solitary waves with good Gaussian shape were excited one after another, forming a train of waves. The simulation also showed that the phase velocities of ions decrease sharply when the solitary wave occurs, which indicates that the solitary ion-acoustic wave is excited via the inverse Landau damping process.
