“…Then multi-ion plasma has been investigated by many scientists both theoretically and experimentally. 31,32,42 In case of the study of DIASWs waves, there are three different types of nonlinear equations, namely, Korteweg-de Vries (K-dV), modified K-dV (mK-dV), and Gardner equations. Ashraf et al 43 have studied the basic characteristics of DIASWs by considering negatively charged stationary dust, ions, and nonextensive electrons in a dusty magnetoplasma.…”

The linear and nonlinear propagations of dust-ion-acoustic solitary waves (DIASWs) in a collisionless four-component unmagnetized dusty plasma system containing nonextensive electrons, inertial negative ions, Maxwellian positive ions, and negatively charged static dust grains have been investigated theoretically. The linear properties are analyzed by using the normal mode analysis and the reductive perturbation method is used to derive the nonlinear equations, namely, the Korteweg-de Vries (K-dV), the modified K-dV (mK-dV), and the Gardner equations. The basic features (viz., polarity, amplitude, width, etc.) of Gardner solitons (GS) are found to exist beyond the K-dV limit and these dust-ion-acoustic GS are qualitatively different from the K-dV and mKdV solitons. It is observed that the basic features of DIASWs are affected by various plasma parameters (viz., electron nonextensivity, negative-to-positive ion number density ratio, electron-to-positive ion number density ratio, electron-to-positive ion temperature ratio, etc.) of the considered plasma system. The findings of our results obtained from this theoretical investigation may be useful in understanding the nonlinear structures and the characteristics of DIASWs propagating in both space and laboratory plasmas.

“…It is often noticed that the velocity distribution of plasma particles in space plasmas as well as in laboratory plasmas are not exactly Maxwellian, and particles follow the distributions that deviated from the Maxwellian distribution [31][32][33]). By considering electron or ion or both electron and ion to be nonextensive, a large number of authors [36][37][38] have studied different types of wave propagation such ion acoustic (IA) waves, electron-acoustic (EA) waves, DIA waves, or dust-acoustic (DA) waves. In present times, nonextensive plasma has become a topic of interest among the researchers.…”

An investigation has been made on heavy ion-acoustic (HIA) nonplanar shocks and solitons in an unmagnetized, collisionless, strongly coupled plasma whose constituents are strongly correlated adiabatic inertial heavy ions, weakly correlated nonextensive distributed electrons and Maxwellian light ions. By using appropriate nonlinear equations for our strongly coupled plasma system and the well-known reductive perturbation technique, a modified Burgers (mB) equation and a modified Korteweg-de Vries (mK-dV) equation have been derived. They are also numerically solved in order to investigate the basic features (viz. polarity, amplitude, width, etc.) of cylindrical and spherical shock/solitary waves in such a strongly coupled plasma system. The roles of heavy ion dynamics, nonextensivity of electrons, and other plasma parameters arised in this investigation have significantly modified the basic features of the cylindrical and spherical HIA solitary and shock waves. The findings of our results obtained from this theoretical investigation may be useful in understanding the nonlinear phenomena associated with the cylindrical and spherical HIA waves both in space and laboratory plasmas.
