Unmagnetized Plasma

The formation of dust ion acoustic solitons in an unmagnetized plasma with the electrons’ drift velocity has been investigated through the modified Korteweg – de Vries (mKdV) equation. In this case only compressive solitons are found to exist. The mKdV solitons are established to exist in two new ranges of drift velocity [Formula: see text] for [Formula: see text] and [Formula: see text].

Ion-acoustic solitons in a plasma with different adiabatic ion constituents and isothermal electrons are studied via a reductive perturbation method. The basic fluid equations then give rise to KdV or modified KdV equations, depending upon the relative ion densities. At critical densities, rarefactive and compressive fast ion-acoustic solitons are possible. Explicit stationary solutions are discussed in the special case of cold ions, in a plasma containing two species of negative ions and one of positive ions. The inclusion of heavier ions, even at low densities, increases the amplitudes of the critical solitons.
