Effect of superthermality on nonlinear electrostatic modes in plasmas
arXiv:1108.3073
Abstract
The nonlinear propagation of electron-acoustic solitary structures is investigated in a plasma containing kappa-distributed (superthermal) electrons. Different types of localized structures are shown to exist. The occurrence of modulational instability is investigated.
