“…When dissipation in the system is large it can overcome the role of dispersion, case when the balance between nonlinearity and dissipation can generate shock waves [30,31,237]. A very effective method for studying these phenomena is the particle-in-cell (PIC) simulation [363,364,365,366].…”

“…We assume the particles are cold and their flow velocity is zero at an initial The time evolution of such a system of charged particles is studied using the particle-in-cell (PIC) method, developed and widely used to investigate the dynamics of a collisionless plasma [363,364,365,366]. By using the PIC method the material medium is represented by a set of particles that move under the influence of an electromagnetic field, which in turn is determined by the particle distributions and their associated electric currents.…”

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.

“…On the other hand, with the main collision features being presented in the long particle chain during the theoretical simulation, a short structure with fewer particles can be applied to the practical test. The material parameters of these particles are listed in Table 1, as well as u LI = u RI = 1 and ε = 0.002 are applied [58][59][60][61]. In order to show the overlap between adjacent particles which result in the no separation during the wave propagation, the prestress is used to the whole periodic system.…”

In this work, the head-on collision and transmission with nonreciprocal properties of opposite propagating solitary waves are studied, in which the interface between different granular chains is considered. Due to the discontinuity of two periodic granular systems, the transmitted and reflected solitary waves are produced. The head-on collision appears at the interface and the reductive perturbation method is applied to derive the generated solitary waves. According to the derivation and numerical simulation, we can find that the transmitted and reflected solitary waves can propagate with the same speed when they locate at the same chain. Moreover, the influences of both the arrangement and prestress are discussed. It is found that the amplitude and velocity of solitary waves become larger because of a bigger prestress, which result in the nonreciprocal collision and transmission in the granular mechanical metamaterials. This study is expected to be helpful for the design and application of elastic wave metamaterials and mechanical diodes with nonlinear solitary waves.

“…Based on wave-particle response interactions used to modify the shape of the solution a detailed study was proposed, as it was observed, these interactions in the plasma lead to the acceleration of charged particles as a result of the transfer of wave energy to these particles 19 . Recently, experimental results have predicted the formation of acoustic ion shock waves due to the dissipation caused by Landau damping 20 . Arnab Barman and A. P. Misra investigated the effect of Landau damping of two types of ions (positive and negative) on electrostatic solitary waves in dusty multicomponent plasma 21 .…”

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.
