Oblique propagation of nonlinear ion-acoustic cnoidal waves in magnetized electron–positron–ion plasmas with nonextensive electrons

Abstract

Theoretical investigation of nonlinear electrostatic ion-acoustic cnoidal waves (IACWs) is presented in magnetized electron–positron–ion plasma with nonextensive electrons and Maxwellian positrons. Using reductive perturbation technique, Korteweg–de Vries equation is derived and its cnoidal wave solution is analyzed. For given plasma parameters, our model supports only positive potential (compressive) IACW structures. The effect of relevant plasma parameters (viz., nonextensive parameter q, positron concentration p, temperature ratio σ, obliqueness l 3) on the characteristics of IACWs is discussed in detail.

Physical aspects of cnoidal waves in non-thermal electron-beam plasma systems

“…Now, we demonstrate the importance of the current study with respect to other works. For this aim, we consider [26][27][28][40][41][42][43][44][45][46][47][48][49][50] for example. In particular, our numerical results are distinct from the results given in these articles.…”

“…On the other hand, in [40,41], the structures of the ion-acoustic cnoidal waves were analyzed in a plasma with two-temperature Kappa distributed electrons. Such conditions for IACWs were also studied in [42,43] for the nonextensive plasmas. Furthermore, the influences of the quantum diffraction parameter and other plasma parameters on cnoidal waves in quantum plasmas were investigated in [44][45][46][47]49].…”

“…Farhadkiyaei and Dorranian [42] investigated the IACWs structures in the nonextensive plasmas. They observed the positive potential nonlinear IA cnoidal structures for all values of non-thermal parameter q. Khalid et al [43] studied IACWs in a magnetized electron-positron-ion plasma with nonextensive electrons. It was illustrated that only compressive cnoidal waves can be propagated in such a plasma model [43].…”

Oblique propagation of ion-acoustic solitary waves in magnetized electron-positron-ion plasma with Cairns distribution

“…The investigation of nonlinear waves [24][25][26][27][28][29][30][31][32][33] in plasma and other dispersive media has received a great deal of attention due to their applications in different areas of physics including the nonlinear ion transport phenomena. In 1895, Korteweg and de Vries (KdV) derived the KdV equation, which is used to describe the dynamics of SWs [34,35].…”

Nonlinear periodic structures in magnetoplasma with nonthermal electrons and positrons

“…The authors in ref. [29] have theoretically investigated the nonlinear electrostatic IACWs in the presence of magnetized plasma with nonextensive electrons and Maxwellian positron. They employed the reductive perturbation technique and derived the KdVE for the analysis of CW solution.…”
