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.

Electrostatic nonlinear waves which transfer energy through the semiconductor are investi-gated. A quantum hydrodynamic plasma system composed of self-streaming electrons and holesis examined. The basic equations are reduced to one evolution equation called a modified nonlin-ear Schr ̈odinger (mNLS) equation. The stability and instability regions are studied with respectto the wavenumber and different plasma effects such as degenerate pressure, Bohm potential, andcollisions. The mNLS equation is solved analytically to obtain three kinds of nonlinear envelopewave packet modes. It is found that there are different regions of stability and instability depend-ing on various quantum effects. The electrons’ and holes’ self-streaming velocity is studied andmanipulated for the three types of nonlinear envelope waves ”dark soliton, bright soliton, androgue wave”. The dark envelope wave packet is generated in a stable region. When the electronsand holes streaming velocities become faster, the wave amplitude becomes taller and the pulseshave higher frequency. The bright envelope wave packet exists in the unstable region. For lowstreaming velocities, the rogue wave amplitude becomes shorter, however, when the streamingvelocities reach a critical value the amplitude increases suddenly six times. The self-heating couldbe produced as the tunneling electrons and holes exchange their energy with the lattice, whichmay decrease the lifetime of the semiconductors. The present results are helpful in realizing thephysical solution to the intrinsic heating problem in semiconductors.

“…It has been found that the nonlinear dusty plasma waves can be affected by the velocity distribution of charged particles. Maxwellian velocity distribution has been the most common probability distribution since it is assumed that the charged particle system has reached thermodynamic equilibrium [10][11][12]. However, should be phase-space holes resulting from electron trapping, the electrons may not follow Maxwellian distribution.…”

Different nonlinear dynamical behavior of dust-acoustic modes of a homogeneous plasma are examined. The plasma composed of negatively charged dust grains and nonextensive distribution electrons and ions. The evolution of the system is investigated using a 3-dimensional nonlinear Schrodinger (3D-NLS) equation. Different methods are used to explore the possible solutions of 3D-NLS equation using a bifurcation analysis and factorization method to obtain periodic, shocklike and explosive waves. Furthermore, rogue wave solution of the 3D-NLS equation is obtained to investigate the dependence of rogue wave profile on nonextensivity parameters. The present investigation can be relevance to the electrostatic structures in various dusty plasmas, such as Saturn's E-ring.
