“…Recently, a bounce of authors has been used NLS equation to understand different nonlinear phenomena (MI and rogue waves), which are observed in laboratory and space plasmas. Abdelwahed et al [25] examined rogue waves characteristics are totally depended on the ionic density ratio, ionic mass ratio, and superthermal parameter in ion pair superthermal plasma. Gill et al [5] studied MI of dust acoustic solitons in multicomponent plasma with kappa distributed electron and ions, where they observed presence of positive dust component modify the domain of the MI and localized envelope excitations.…”

The modulational instability of dust-acoustic (DA) waves (DAWs), and corresponding DA rogue waves (DARWs) in a realistic space dusty plasma system (containing inertial warm positively and negatively charged dust, isothermal ions, and nonthermal kappa distributed electrons) has been theoretically investigated. The nonlinear Schrödinger (NLS) equation is derived by using reductive perturbation method for this investigation. It is observed that the dusty plasma system under consideration supports two modes, namely fast and slow modes, and that both of these two modes can be stable or unstable depending the sign of ratio of the dispersive and nonlinear coefficients. The numerical analysis have shown that the basic features (viz. stability/instabilit, growth rate, amplitude, etc.) of the DAWs associated with the fast mode are significantly modified by superthermal parameter (κ) and other various plasma parameters. The results of our present investigation should be useful for understanding DARWs in space plasma systems, viz. mesosphere and ionospehre.

“…The field of MI and RWs has been considered one of the highly interdisciplinary areas of research involving plasma physics, [12] oceanography, [28] Bose-Einstein condensation, [29] optics, [30] superfluid helium, [31] and even finance [32] A number of authors have theoretically studied different criteria of MI and RWs in many PIPM [3,12,33] and confirmed them in laboratory experiments. The nonlinear Schrödinger equation (NLSE) admits interesting rational solutions named rogue waves (RWs), also known as freak waves, extreme waves, and killer waves, in the MI region.…”

“…Researchers have devoted their attention to solve the mystery of these colossal waves because of their intrinsically arbitrary nature and their complex formation mechanisms. Abdelwahed et al [33] studied IA rogue waves (IARWs) in PIPM in the presence of super-thermal electrons.

The non-linear propagation of ion acoustic (IA) waves, which is governed by the non-linear Schrödinger equation, in multi-pair plasmas (MPPs) containing adiabatic positive and negative ion fluids as well as non-extensive (q-distributed) electrons and positrons is theoretically investigated. It is observed that the MPP under consideration supports two types of modes, namely fast and slow IA modes, and the modulationally stable and unstable parametric regimes for the fast and slow IA modes are determined by the sign of the ratio of the dispersive coefficient to the non-linear one. It is also found that the modulationally unstable regime generates highly energetic IA rogue waves (IARWs), and the amplitude as well as the width of the IARWs decreases with increase in the value of q (for both q > 0 and q < 0 limits). These new striking features of the IARWs are found to be applicable in the space (i.e., D-region [H + , O − 2 ], and F-region [H + , H − ] of the Earth's ionosphere) and laboratory MPPs (i.e., fullerene [C + , C − ]).

“…The results were shown to be important in the D-and F-regions of the Earth's ionosphere. In an another work, Abdelwahed et al [27] investigated the propagation of rogue waves in superthermal plasmas with a pair of ions. Different characteristics of the rogue waves so generated have been studied by the effects of the number densities as well as the superthermality of ions.…”

Nonlinear dust-acoustic solitary waves and shocks in dusty plasmas with a pair of trapped ions

Abstract:The propagation characteristics of small-amplitude dust-acoustic (DA) solitary waves (SWs) and shocks are studied in an unmagnetized dusty plasma with a pair of trapped positive and negative ions. Using the standard reductive perturbation technique with two different scaling of stretched coordinates, the evolution equations for DA SWs and shocks are derived in the forms of complex Korteweg-de Vries (KdV) and complex Burgers' equations. The effects of dust charge variation, the dust thermal pressure, and the ratios of the positive to negative ion number densities as well as the free to trapped ion temperatures on the profiles of SWs and shocks are analysed and discussed.
