Nonlinear dust acoustic waves in a nonuniform magnetized complex plasma with nonthermal ions and dust charge variation

摘要: Propagations of nonlinear dust acoustic (DA) solitary waves and shock in a nonuniform magnetized dusty plasma are investigated. The incorporation the combined effects nonthermally distributed ions, nonadiabatic charge fluctuation, inhomogeneity caused by equilibrium values particle density, charging variable, potential on leads to significant modification nature DA waves. wave evolution is governed modified Zakhavov-Kusnetsov-Burgers (MZKB) equation, whose coefficients space dependent. Using generalized expansion method, new solutions for MZKB equation obtained. form consists two parts; one them amplitude factor other superposition bell-shaped kink-type New classified into three categories. A type solution determined depending nonthermal parameter. Findings this investigation should be useful understanding ion acceleration mechanisms close Moon also enhancing our knowledge pickup ions around unmagnetized bodies, such as comets, Mars, Venus, including medium inhomogeneities with processes.
