The behavior of linear and nonlinear dust acoustic waves (DAWs) in an unmagnetized plasma including inertialess electrons and positrons, ions, and mobile positive/negative dust grains are studied. Reductive perturbation method is employed for small and finite amplitude DAWs. To investigate the solitary waves, the Korteweg–de Vries (KdV) equation is derived and the solution is presented. B...

The closed, energy conserving system of electromagnetic-plasma equations describing the classical beat wave accelerator are shown to lead to an intrinsic lim it on the acceleration efficiency due to the pump depletion effect producing an intense trail of plasma waves. We propose and analyze with theory and simulations a wakeless accelerating structure composed of a nonlinear vector soliton. The...

: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...

Abstract In this paper, we investigate the modified Kadomtsev–Petviashvili-II (mKP-II) equation, which has important applications in fluid dynamics, plasma physics and electrodynamics. By utilizing Hirota bilinear method, N-soliton solutions of mKP-II equation are obtained. The resonance Y-type soliton, interaction between M-resonance solitons P-resonance constructed by imposing some constraint...
