Dissipative longitudinal solitons in a two-dimensional strongly coupled complex (dusty) plasma.
TLDR
Solitary waves are experimentally studied in a monolayer hexagonal dust lattice which is formed from monodisperse plastic microspheres and levitated in the sheath of an rf discharge and it is found that the product of thesoliton amplitude and the square of the soliton width is constant as the solitons propagates.Abstract:
Solitary waves are experimentally studied in a monolayer hexagonal dust lattice which is formed from monodisperse plastic microspheres and levitated in the sheath of an rf discharge. It is found that the product of the soliton amplitude and the square of the soliton width is constant as the soliton propagates. The analytical theory describing the experiment is based on the equations of motion written for a linear chain. It takes into account damping, dispersion, and nonlinearity. The numerical simulation of a linear chain produces double solitons like those observed in the experiment.read more

Complex (dusty) plasmas: current status, open issues, perspectives
TL;DR: The field of complex (dusty) plasmas is reviewed in this paper, where the major types of experimental complex Plasmas are briefly discussed, including grain charging in different regimes, interaction between charged particles, and momentum exchange between different species.

Complex plasmas: An interdisciplinary research field
TL;DR: Complex (dusty) plasmas are composed of a weakly ionized gas and charged microparticles and represent the plasma state of soft matter as discussed by the authors, and they can be easily manipulated in different ways, also at the level of individual particles.

Solitons, shocks and vortices in dusty plasmas
TL;DR: In this article, the effects of nonplanar geometry, dust grain charge fluctuations, dust fluid temperature, vortex-like ion distribution, strong dust correlation etc on the properties of dust ion-acoustic/dustacoustic solitons have also been analysed.

Experimental study of nonlinear dust acoustic solitary waves in a dusty plasma.
TL;DR: The excitation and propagation of finite-amplitude low-frequency solitary waves are investigated in an argon plasma impregnated with kaolin dust particles and the velocity and width increase and the width decreases with the increase of the modulating voltage, but the product of the solitary wave amplitude and the square of the width remains nearly constant.

Soliton interaction in a complex plasma.
TL;DR: It was found that the solitons are delayed after the collision, andsolitons with higher amplitude experience longer delays.
