“…A study of the characteristics of freak waves in dusty plasma containing two temperatures ions is presented in [361], by modulating the KP equation to infer the nonlinear Schrdinger equation (NLSE). Nonlinear propagation of dust-acoustic (DA) solitary waves [359,368] in a three-component unmagnetized dusty plasma consisting of Maxwellian electrons, vortex-like (trapped) ions and arbitrarily charged cold mobile dust rain, is investigated in [369]. It is demonstrated that the dynamics of small but finite amplitude DA waves is regulated by a nonlinear equation of modified Korteweg-de Vries (mK-dV) type.…”

Charged (nano)particles confined in electrodynamic traps can evolve into strongly correlated Coulomb systems, which are the subject of current investigation. Exciting physical phenomena associated to Coulomb systems have been reported such as autowave generation, phase transitions, system self-locking at the ends of the linear Paul trap, self-organization in layers, or pattern formation and scaling. The dynamics of ordered structures consisting of highly nonideal similarly charged nanoparticles, with coupling parameter of the order Γ = 10 8 is investigated. This approach enables us to study the interaction of nanoparticle structures in presence and in absence of the neutralizing plasma background, as well as to investigate various types of phenomena and physical forces these structures experience. Applications of electrodynamic levitation for mass spectrometry, including containment and study of single aerosols and nanoparticles are reviewed, with an emphasis on state of the art experiments and techniques, as well as future trends. Late experimental data suggest that inelastic scattering can be successfully applied to the detection of biological particles such as pollen, bacteria, aerosols, traces of explosives or synthetic polymers.

“…Both theoretical and experimental study of shock waves has been found in recent years [18][19][20][21]. In the case of the production of shock waves in dusty plasma, there exists a good number of theoretical and experimental works [21][22][23][24]. Shock waves can generally be produced in plasma if there is a dissipative force present in the plasma [25].…”

A viscous dusty plasma containing Kappa-(κ−) distributed electrons,positive warm viscous ions and constant negatively charged dust grains with viscosity have been considered to study the modes of dust-ion-acoustic waves (DIAWs) theoretically and numerically. The derivations and basic features of shock and solitary waves with different plasma parameters like Mach number, finite temperature coefficient, unperturbed dust streaming velocity, kinematic viscosity of dust etc. of this DIAWs mode have been performed. Considering the dynamical equation from Korteweg–de Vries(KdV) equation, a phase portrait has been drawn and the position of saddle point or col. and center have also been discussed. This type of dusty plasma can be found in celestial bodies. The results of this research work can be applied to study the properties of DIAWs in various astrophysical situation where κ-distributive electrons are present and careful modification of the same model can help us to understand the nature of the DIAWs of laboratory plasma as well.
