“…But they did not consider magnetic field. Later Haider et al [23] have also studied the propagation of SWs in the presence of magnetized plasma with both positive and negative ions fluid, vortex-like distributed electrons and charge fluctuating stationary dusts. They have derived modified Korteweg-de Vries (mK-dV) equation and its solution.…”

An attempt has been made to find out the effects of trapped electrons in dust-ion-acoustic solitary waves in magnetized multi-ion plasmas, as in most space plasmas, the hot electrons follow the trapped/vortex-like distribution. To do so, we have derived modified Zakharov-Kuznetsov equation using reductive perturbation method and its solution. A small-k perturbation technique was employed to find out the instability criterion and growth rate of such a wave.

“…Mishra et al [4] studied the obliquely propagating ion-acoustic solitary waves in a multi-component magnetized plasma consisting of warm adiabatic positive and negative ion species and hot isothermal electrons. Haider et al have studied the nonlinear propagation of IA solitary waves with EPIs and ENIs for Maxwellian [6,5], trapped [7,8], and nonthermal [9,10] distributed electrons. Nakamura and Tsukabayashi [11] have studied experimentally the propagation of ion-acoustic solitons in a plasma with negative ions.…”

An attempt has been taken to study the nonlinear propagation of electro-positive heavy ion-acoustic (EPHIA) solitary and shock waves in multi-component plasmas containing mobile electro-positive heavy ions (EPHIs), nonthermal distributed electro-negative light ions (ENLIs) and Maxwellian electrons. The effects of temperature, mobile EPHIs, ENLIs and its nonthermality on solitary and shock waves are investigated in present work. To do so, we have derived the standard Korteweg-de Vries (K-dV) and Burger equations and their solutions. We have studied the effects of the parametric regimes, which affect the solitary and shock waves, numerically as well as graphically.4. Below (above) the critical value of ENLIs concentration the solitary and shock waves are associated with positive (negative) potentials. And also negative (positive) potentials are found below (above) the critical value of the nonthermal parameter (α). 5. Maxwellian electrons concentration makes the lower amplitude solitary and shock waves. 6. The width of solitary structures decreases with increasing α, σ p , µ n and µ e ; i.e. the solitary waves will be spiky for the higher values of these. 7. The width of the shock waves is a linear function of the viscus coefficient, i.e. spiky profile of the shock waves are found for the lower value of the viscus coefficient.We hope that our present investigations may be helpful to understand the effect of heavy ion on EPHIA solitary and shock waves in multi-component electron-ion plasmas in laboratory and astrophysical system like radio wave propagation in the ionosphere [12] and also give a guideline to further development in the relevant field.

“…Very recently many authors have studied the nonlinear propagation of ion-acoustic (IA) solitary waves (SWs) [1][2][3][4] dust-ion-acoustic (DIA) SWs [5][6][7][8][9], dust-acoustic (DA) SWs [10][11][12][13][14] in a multi-ion plasmas, as negative ions can be found in space [15,16] and laboratory [17][18][19] as well as positive ions. In multi-ion plasmas, there exist fast and slow mode.…”

An attempt has been made to study the multidimensional instability of dust-ion-acoustic (DIA) solitary waves (SWs) in magnetized multi-ion plasmas containing opposite polarity ions, opposite polarity dusts and nonthermal electrons. First of all, we have derived ZakharovKuznetsov (ZK) equation to study the DIA SWs in this case using reductive perturbation method as well as its solution. Small-k perturbation technique was employed to find out the instability criterion and growth rate of such a wave which can give a guideline in understanding the space and laboratory plasmas, situated in the D-region of the Earth's ionosphere, mesosphere, and solar photosphere, as well as the microelectronics plasma processing reactors.
