Abstract A viscous dusty plasma containing Kappa-( κ − ) distributed electrons, positive warm ions, and constant negatively charged dust grains with viscosity have been considered to study the modes of dust-ion-acoustic waves (DIAWs) theoretically numerically. The derivations basic features shock solitary different parameters like Mach number, finite temperature coefficient, unperturbed streami...

Complex (dusty) plasmas consist of micron sized microparticles immersed into ordinary ion-electron plasmas. They can exist in solid, liquid or gaseous states and exhibit a range of dynamic phenomena such as linear and nonlinear dust waves, solitons, shocks, Mach cones, heat transfer by phonons, flows, etc. We report on the experimental and numerical study of dissipative solitons in complex plas...

Optical gap solitons, which exist due to a balance of nonlinearity and dispersion due to a Bragg grating, can couple to acoustic waves through electrostriction. This gives rise to a new species of "gap-acoustic" solitons (GASs), for which we find exact analytic solutions. The GAS consists of an optical pulse similar to the optical gap soliton, dressed by an accompanying phonon pulse. Close to t...

The nonlinear phenomenon of synchronization is characterized experimentally for dust density waves, i.e., dust acoustic waves, which are self-excited due to an ion streaming instability. The waves propagate in a dust cloud with a natural frequency of 22 Hz. We synchronize these waves to a different frequency using a driving electrode that sinusoidally modulates the ion density. We study four sy...

An opposite polarity dusty plasma system (containing inertial positive as well negative dust species and inertialess singly charged ion species) is considered. The nature of the electrostatic self-gravitational potential structures (associated with dust-acoustic waves) identified by numerical analysis two coupled second-order nonlinear differential equations. latter are Poisson’s equations for ...
