Periodic and localized structures in a degenerate Thomas-Fermi plasma

Electron acoustic solitary waves in unmagnetized nonthermal plasmas

“…To solve equation (19), we define a traveling-wave transformation η=ς−v 0 τ, in respect of which the wave is stationary, where v 0 is the velocity of the EASW. Using this transformation, equation (19) takes the following form…”

“…Moving to a study of the EASW, the nonlinear coefficient, A, and the dispersion coefficient, B, present in the KdV equation (19) are functions of various relevant plasma parameters. These parameters affect the structural characteristics of the pulses and may therefore lead to the generation of various kinds of EA solitary structures in a given plasma system.…”

“…The study of nonlinear periodic waves has gained considerable interest within plasma physics; some examples are mentioned in [4,[13][14][15][16][17][18][19][20][21]. The properties of EAWs that propagate obliquely in magnetized plasmas composed of a cold magnetized electron fluid and a hot vortex-like distribution of electrons and ions were discussed by Mamun and Shukla, they studied the effects of the external magnetic field and obliqueness and found that they changed important properties of EAWs, such as amplitude and width [21].…”

Dust Ion Acoustic Solitary Waves in Unmagnetized Plasma with Kaniadakis Distributed Electrons

“…The detailed description of the aforementioned new acoustic modes seen in Refs. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] has a unique value in astrophysical phenomena. The physical mechanism involved in DIAWs is similar to the IAWs, wherein the restoring force is provided by the inertialess electron while inertia comes from the ion mass.…”

Nonlinear periodic structures in magnetoplasma with nonthermal electrons and positrons

“…Nonlinear ion transport induced by a periodic IA pulse is one of these applications. In recent years, much emphasis has been placed on the study of nonlinear periodic (cnoidal) waves [21][22][23][24][25]. The study of nonlinear periodic waves in plasma physics has picked the interest of many investigators, for more details see ref.…”
