Face to Face Collisions of Ion Acoustic Multi-Solitons and Phase Shifts in a Dense Plasma

Collisional positron acoustic soliton and double layer in an unmagnetized plasma having multi-species

“…To examine the collisional wave phenomena between two-counter propagating soliton and their corresponding phase shift, one can use the following starching coordinates 39 – 41 , 49 : where and are the trajectories of soliton moving headed for each other, and is the phase speed of PAWs and . Also, the perturbed variables can expand based on the concept of ePLK method 3 , 13 , 17 as …”

“…One can then implement the exhausting mathematical procedures (EMPs) to solve the TMEs. Many researchers 3 – 22 have already studied the features of various kinds of acoustic wave phenomena by assuming EPI plasma involving different distributed lighter plasma particles via EMPs. Since various plasma species are inhabited in the different regions of phase space 23 .…”

Effect of Space Fractional Parameter on Nonlinear Ion Acoustic Shock Wave Excitation in an Unmagnetized Relativistic Plasma

“…Most of the physical issues in such plasmas are still not possible to examine in laboratories. But, it may easily describe by the tedious mathematical techniques [11][12][13][14][15][16][17][18][19][20][21]. On the other hand, the shock wave excitation (SWE) is one of the most credible structures based on the outward propagating in various ASEs.…”

“…Further, NLEEs are widely applicable for understanding the formation of wave structures not only in plasma physics but also in water wave theories, optics, fluid dynamics, etc. Many kinds of NLEEs have already derived from the considered model equations by taking distinct ASEs into account [11][12][13][14][15][16][17][18][19][20][25][26][27]. In all previous studies [16,18,[24][25][26][27], the authors have reported the influence of plasma parameters on nonlinear ion acoustic shock wave excitations (NIASWEs) in the relativistic plasmas by deriving NLEEs of integer order for the case of the locality and conservative energies of plasma particles.…”

Dynamical plane wave solutions for the Heisenberg model of ferromagnetic spin chains with beta derivative evolution and obliqueness

“…It is noted that represents the normalized complex amplitude of the wave profile. Many research scholars [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] have devoted significant effort to revealing various types of traveling wave solutions for mathematical physics equations like Eq. (1) by considering many environments via several types of theoretical and computational architectures.…”
