“…The presence of dust, which has a large mass and charge relative to the plasma components, contributes to the emergence of new low-frequency nonlinear modes in the dust plasma. As in the case of dust ion-acoustic (DIA) nonlinear mode [7][8][9] , and dust acoustic (DA) nonlinear mode [10][11][12] .…”

Dust acoustic (DA) solitary waves have been investigated under the influence of Landau damping in space dusty plasma with q-nonextensive velocity distributed of ions. The effect of the Landau damping, and nonextensive parameter q of the ions on DA solitary structures has been illustrated by a numerical solution of the Landau damping modified KdV equation. By applying the reductive perturbation technique (RPT) Korteweg-de Vries (KdV) an equation with an additional Landau damping term for our model has been derived. This study showed that the density of dusty particles plays an essential role in appearance or disappearance of DA solitary waves in dusty plasmas, and the nonextensive character of the ions has a noteworthy influence on the Landau damping phenomenon and formed nonlinear structures; the study provides a way to illustrate the physical mechanism of nonlinear propagation of DA solitary waves under Landau damping in the nonextensive distributed plasma in many fields, such as planetary areas, magnetospheres, and space plasma environments.

“…Supporting and extending experimental possibilities concerning solitons in dusty plasma, theoretical studies focused on the effects of charge-varying dusty plasma with nonthermal electrons [32], of an external magnetic field [33], of the external periodic perturbations and damping [34], as well as of the presence of dust particles with opposite polarities [35]. The effects of dust-ion collision [36], and the possibility of cylindrical solitary waves [37] were also addressed.…”

We investigate via Molecular Dynamics simulations the propagation of solitons in a twodimensional many-body system characterized by Yukawa interaction potential. The solitons are created in an equilibrated system by the application of electric field pulses. Such pulses generate pairs of solitons, which are characterized by a positive and negative density peak, respectively, and which propagate into opposite directions. At small perturbation, the features propagate with the longitudinal sound speed, form which an increasing deviation is found at higher density perturbations. An external magnetic field is found to block the propagation of the solitons, which can, however, be released upon the termination of the magnetic field and can propagate further into directions that depend on the time of trapping and the magnetic field strength.
