“…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. The basic characteristics and propagation of dust-acoustic (DA) shock waves (DASHWs) [161] in self-gravitating dusty plasmas containing massive dust of opposite polarity, trapped ions, and Boltzmann electrons are explored in [370,371]. The reductive perturbation technique is applied to infer the standard modified Burgers equation (mBE).…”

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.

“…Sharma et al [21] have studied the Jeans instability and low frequency modes in dusty plasma, including non-thermal ions, Maxwellian electrons, dust polarization force and charge fluctuation. Considering superthermal electrons and non-thermal ions in dusty plasma, Emamuddin and Mamun [22] have examined dust acoustic shock waves. Furthermore, most of the studies mentioned above have been carried out for homogeneous dusty plasmas.…”

The characteristics of radiative gravitational modes in non-thermal magnetized dusty plasma with charge fluctuation and the polarization force of dust particles are investigated. The electron species are assumed to be radiative and the ions are assumed to be non-thermal. A normal mode analysis is applied to derive the general dispersion relation for radiative magnetized selfgravitating dusty plasma. Modified radiative condensation and self-gravitational instability criteria for both perpendicular and parallel modes of propagation are obtained. Analytically, it is found that the presence of a non-thermal ion population significantly modified the usual radiative condensation instability criterion, and damped the growth rate of the radiative mode. The obtained analytical results are further discussed in the numerical result section. We investigate the fact that the non-thermal ion population acts as a stabilizing source for radiative condensation instability in magnetized self-gravitating dusty plasma fluid, including the dust polarization force and charge fluctuation. The thermal conductivity with non-thermal ion distribution quickly moves the system towards stability. The implications of the results in the region of the interstellar medium (ISM) are discussed.

“…These highly energetic particles are governed by super-thermal (κ)distribution [20], and the parameter κ in the κ-distribution presents the deviation of energetic particles from the thermally equilibrium state. The κ-distribution becomes Maxwellian distribution for large values of κ (i.e., κ → ∞) [21,22,23,24]. Emamuddin and Mamun [22] examined the dust-acoustic shock waves in a multi-component plasma medium having superthermal electrons, and found that the width of the shock profile decreases with the super-thermal effect of the electrons.…”

A proper theoretical research has been carried out to explore the modulational instability (MI) conditions of dust-ion-acoustic (DIA) waves (DIAWs) in a three-component dusty plasma system containing inertialess κ-distributed electrons, and inertial warm positive ions and negative dust grains. The novel nonlinear Schrödinger equation (NLSE) has been derived by employing reductive perturbation method. The analysis under consideration demonstrates two types of modes, namely, fast and slow DIA modes. The dispersion and nonlinear properties of the plasma medium as well as the MI conditions of DIAWs and the configuration of the energetic rogue waves (RWs) associated with DIAWs in the Modulationally unstable regime have been rigorously changed by the plasma parameters, namely, charge, mass, temperature, and number density of the plasma species. The findings of our investigation will be useful in understanding the criteria for the formation of electrostatic RWs in both astrophysical environments (viz., Jupiter's magnetosphere, cometary tails, Earth's mesosphere, Saturn's rings, etc.) and laboratory experiments (viz., Q-machines and Coulomb-crystal).
