“…Iqbal et al investigated the propagation of nonlinear coupled drift ion acoustic shock waves in an e-p-i plasma where they considered the presence of adiabatically trapped electrons [14]. Khalid et al conducted a theoretical investigation on oblique propagation of ion acoustic solitary waves in an e-p-i plasma in the presence of nonthermal particles following the Cairns distribution [15]. Recently Almas et al investigated the propagation properties of ion acoustic solitary waves (IASWs) in a non-Maxwellian e-p-i plasma by using Sagdeev's pseudopotential theory [16].…”

A magnetized nonthermal electron-positron-ion (e-p-i) plasma is considered to study the propagation properties of ion-acoustic solitary and shock waves in the presence of trapped positrons and electrons for the first time. The Schamel-$\kappa$ (kappa) distribution function describing the plasma nonthermality as well as particle trapping is assumed to consider electrons and positrons. The diffusive effect of ion plasma fluid, which is responsible for shock dynamics is taken into account. A nonlinear Schamel-Korteweg-de Vries-Burgers' (SKdVB) equation is derived by employing the reductive perturbation approach, and the solitary and shock wave solutions of the SKdVB equation have also been derived for different limiting cases. It is found that only positive potential nonlinear structures (for both solitary and shock waves) are formed in the proposed plasma system. The condition for stable solitons in the absence of dissipation is analysed and the nature of arbitrary amplitude solitary waves (obtained via the Sagdeev potential approach) is discussed. It is investigated theoretically and numerically that different plasma compositional parameters [such as the trapping effect of electrons ($\beta_e$) and positrons ($\beta_p$), the obliquity effect ($\theta$), electron-to-ion number density ratio ($\mu_e$), the magnetic field effect (via $\Omega$) and the viscous effect ( via $\eta$)] have significant influence on the dynamics ion-acoustic solitary and shock waves. The theoretical and numerical investigations in this study may be helpful in describing the nature of localised structures in different plasma contexts, e.g., space and astrophysical plasmas, experimental plasmas where electron-positron-ion plasmas exist.

“…The importance of the e-p-i plasma has led to a considerable amount of investigations. In the last few decades, there has been a rapidly growing interest [22][23][24][25][26][27][28][29][30][31][32][33] in studying both linear and nonlinear waves in such kinds of plasma. Therefore, in the present study, a typical e-p-i plasma [33] was chose as an example to give a detailed theoretical investigation for the boundary effects on dispersion relations of IA wave and physical properties of overlapping soliton.…”

Taking into account the cylindrical boundary, a theoretical investigation has been made for the low frequency electrostatic waves in an electron-positron-ion plasma waveguide. The dispersion relation of ion-acoustic (IA) wave is obtained, and a predication for the linear interaction phenomenon of small-amplitude cylindrical IA solitons is presented. It is shown that the cylindrical boundary has significant effects on the dispersion property of IA waves, and the frequency for short wave is significantly modified by the plasma parameters. It has also been noted that cylindrical IA solitons add up linearly when they overlap and penetrate through each other, the maximum amplitude of the overlapping soliton is nearly the sum of the individual soliton amplitude, indicating an apparent linear interaction. Furthermore, the relationships between phase delay and kinetic energy of colliding solitons for an axisymetric cylindrical geometry are derived and discussed in detail. The work presented would be useful to enrich the solitons interaction theory in astrophysical and laboratorial plasma situations.
