“…The most fundamental normal modes in a dusty plasma are the dustacoustic (DA) (Rao et al, 1990) and dust-ion-acoustic (DIA) (Shukla and Silin, 1992) modes, which have been observed in laboratory experiments (Barkan et al, 1995;Barkan et al, 1996). Several distinct features of the linear waves have been confirmed later by analytical and experimental analyses (Shukla and Mamun, 2002) and new characteristics for nonlinear waves were explained by using various plasma compositions including the nonthermal character and magnetic field effects in dusty plasmas (Barkan et al, 1995;Barkan et al, 1996;Shukla and Mamun, 2002;Shukla and Mamun, 2003;Masood et al, 2010a;Masood et al, 2010b;Masood et al, 2012;Sabeen et al, 2017;Nawaz et al, 2022;Shohaib et al, 2022).…”

By using the framework of kinetic model, the test charge driven response of a dusty plasma is evaluated in the presence of polarization force. The plasma containing electrons, singly ionized positive ions, and highly charged negative dust particulates is known as a dusty plasma, which can be perturbed by a test particle of charge qT moving with velocity vT along the z-axis. The polarization force purely comes from the high charging state of micron-sized dust particles, causing a deformation of shielding length due to density gradient and modifying the collective motion and particulates’ acceleration. The application of Fourier transformation technique to the set of dynamical equations may result in the shielded potential for a test charge with a modified dielectric constant. Several possibilities have been explored to evaluate the shielded potentials by imposing different conditions on the test charge speed in comparison with the thermal speeds of plasma species. It is found that the profiles of wakefield, Debye-Hückel and farfield (FF) potentials are strongly modified by the polarization force coefficient via the dust charging state and dust concentration. The present findings are useful in the study of strongly coupled dusty plasma, where micron-sized negatively charged dust grains are characterized by a high charging state.

“…The dusty plasma, also known as complex plasma, is like ordinary (electron-ion ( e − i )) plasma system with the addition of micro or nano-sized charged dust grains. 1,2 The addition of dust particles alters the usual linear and nonlinear e − i plasma modes, by virtue of the variation of the charge, mass, number, and size of dust particles, to the dust-acoustic waves (DAWs), 3,4 the DIAWs, 5 the dust-ion acoustic (DIA) rogue waves (DIARWs), 6 DIA dissipative solitons, 7 the dust lattice waves, 8 etc. in the plasma system.…”

The characteristics of (non)linear dust-ion acoustic waves (DIAWs) in a collisionless, magnetized dusty plasma are investigated. The current model is composed of ( r, q)-distributed electrons along with warm ions and stationary dust grains with negative charge. Both linear and nonlinear waves are considered to progress in x- z plane. The properties of linear waves are studied by deriving the dispersion relation for the plasma parameters of Saturn’s magnetosphere. The fluid equations of the current model are reduced to the universal Korteweg-de Vries (KdV) equation in order to study the characteristics of oblique propagation of DIA solitary waves (DIASWs). The critical point at which the nature/polarity of solitons changes is determined precisely. The influence of various plasma parameters, namely, obliqueness, magnetic field, densities, temperatures, and double spectral indices of the ( r, q)-distributed electrons on DIASWs is investigated for Saturn’s magnetosphere. The DIASWs of ( r, q)-distributed electrons are also compared with Maxwellian electrons. This work would be helpful to study other astrophysical and laboratory plasma systems where dusty plasmas and ( r, q) distribution are predicted.

“…Nonlinearities are another essential feature of fractional systems, as they can lead to the emergence of rich and diverse phenomena, such as chaos, bifurcations, solitons, and patterns. Nonlinear systems are ubiquitous in nature and technology, and understanding their dynamics is crucial for predicting and controlling their behavior [16][17][18][19][20][21][22][23].…”

Analytical analysis of fractional nonlinear Jaulent-Miodek system with energy-dependent Schrödinger potential

In this work, a novel technique is considered for analyzing the fractional-order Jaulent-Miodek system. The suggested approach is based on the use of the residual power series technique in conjunction with the Laplace transform and Caputo operator to solve the system of equations. The Caputo derivative is applied to express the fractional operator, which is more suitable for modeling real-world phenomena with memory effects. As a real example, the proposed technique is implemented for analyzing the Jaulent-Miodek equation under suitable initial conditions. Additionally, the proposed technique’s validity (accuracy and effectiveness) is examined by studying some numerical examples. The obtained solutions show that the suggested technique can provide a reliable solution for the fractional-order Jaulent-Miodek system, making it a helpful tool for researchers in different areas, including engineering, physics, and mathematics. We also analyze the absolute error between the derived approximations and the analytical solutions to check the validation and accuracy of the obtained approximations. Many researchers can benefit from both the obtained approximations and the suggested method in analyzing many complicated nonlinear systems in plasma physics and nonlinear optics, and many others.
