Some Models in Unmagnetized Plasma involving Kaniadakis Distributed Electrons and Temperature Ratio: Dust Ion Acoustic Solitary Waves

Abstract

The current paper studies the influence of the temperature ratio of ion-to-electron α, dust concentration μ, and κ- deformed parameter on dust ion acoustic solitary waves in an unmagnetized plasma with Kaniadakis distributed electrons. More precisely, the reductive perturbation technique is utilized to extract the Korteweg-de Vries and modified Korteweg-de Vries equations. Both compressive and rarefactive Korteweg-de Vries solitons are found to exist in the ranges 0 < μ ≤ 0.677 and 0.677 < μ < 1, respectively, and only compressive modified Korteweg-de Vries solitons in the range 0 < μ ≤ 0.11. In an unmagnetized plasma with Kaniadakis distributed electrons, the influence of the ion-to-electron temperature ratio on dust ion acoustic solitary waves can have several fascinating applications and consequences in plasma physics and astrophysics.
