“…We note that though the parameter regimes over which these experimental works are carried out favours decrease of the Landau damping rate , an actual numerical evaluation of the same via Eq.

We also note here that in absence of any dust dynamics, the effect of dust charge on Landau damping of ion acoustic wave, as per Eq.…”

A new hybrid-particle-in-cell (PIC)-Monte Carlo Collision (h-PIC-MCC) algorithm is presented here. The code correctly simulates the damping of ion acoustic wave due to dust charge fluctuation in a dusty plasma along with other kinetic effects such as Landau damping. In the model, on event of a collision between a charged particle and a dust particle, a randomised probability determines whether the charged particle is absorbed by the dust with the collision cross section being determined dynamically by the overall interaction scenario. We find that this method is versatile enough as it can also include the size and mass distribution for the dust particles, in addition to the charged species dynamics. As such, it can be adopted to study numerous phenomena that occur in diverse dusty plasma environments. We believe that the damping of the ion acoustic wave through dust charge fluctuation is being demonstrated, for the first time, with a PIC code, in this work.

The effects of nonextensive electrons on nonlinear ion acoustic waves in dusty negative ion plasmas with ion–dust collisions are investigated. Analytical results show that both solitary and shock waves are supported in this system. The wave propagation is governed by a Korteweg–de Vries Burgers-type equation. The coefficients of this equation are modified by the nonextensive parameter q. Numerical calculations indicate that the amplitude of solitary wave and oscillatory shock can be obviously modified by the nonextensive electrons, but the monotonic shock is little affected.

“…Previous work on the effect of charged dust particles on the collisionless damping of ion-acoustic surface waves propagating at the interface of a semi-bounded plasma and a vacuum can be found in ref. [18]. In this reference, the increase of the damping rate was observed as either the density of dust particles or the amount of dust charge increases.…”

The non-thermal effects on the low-frequency ion-acoustic Trivelpiece-Gould (TG) wave are examined in a Lorentzian weakly ionized dusty plasma waveguide such as Hanyang University Diverter Plasma Simulator-2 (DiPS-2). By using the normal mode analysis and the separation of variables, the dispersion relation and the damping modes are obtained for the low-frequency ion-acoustic TG wave in a Lorentzian weakly ionized dusty plasma waveguide. With typical conditions of DiPS-2 such as plasma density n_e = n_i < 10^11 cm^-3, ion-neutral collision frequency is 20kHz, electron temperature T_e = 1 ~ 10 eV, and ion temperature T_i = 0.1 eV, followings are found: (1) the magnitude of the damping rates of the low-frequency ion-acoustic TG wave in Lorentzian plasmas are always greater than those in Maxwellian plasmas; (2) the propagation mode of the ion-acoustic TG wave can be existed for a longer period of time as a decrease of the geometrical size of the radius of the waveguide; (3) the ion-acoustic TG wave for the first harmonic mode, can also be existed for the shortest period of time; (4) the ion-acoustic TG wave in a smaller waveguide can be existed for a wide range of the wave number; and (5) the non-thermal character of a Lorentzian plasma enhances the anti-symmetric behavior of the damping rate for the ion-acoustic TG wave.
