چکیده
The linear electron acoustic waves propagating in plasmas with two kappa-distributed electrons and stationary ions are investigated. temperatures of the assumed to be same, but kappa indices not. It shows that if one index is small enough other large enough, a weak damping regime exists. dispersions rates numerically studied. parameter spaces for weakly damped analyzed. Moreover, present model compared those models, especially two-temperature electrons. At last, we perform Vlasov–Poisson simulations verify theory.

Dust Acoustic Shock Waves in Coupled Dusty Plasmas with Kappa-Distributed Ions
We have considered an unmagnetized dusty plasma system consisting of ions obeying superthermal distribution and strongly coupled negatively charged dust. We have used reductive perturbation method and derived the Kordeweg-de Vries-Burgers (KdV-Burgers) equation. The behavior of the shock waves in the plasma has been investigated. Keywords—Shock, Soliton, Coupling, Superthermal ions.
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...

Investigation of Dust-Ion Acoustic Waves in a Magnetized Collisional Dusty Plasma with Kappa Distribution Function for Electrons
The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...
متن کاملExperimental Investigation of Electron-Acoustic Waves in Electron Plasmas
Electron-acoustic waves have strong linear Landau damping, but are observed as nonlinear BGK modes in experiments with pure electron plasmas. The waves have phase velocity vφ ≈ 1.3v̄, in agreement with theory, and the longest wavelength BGK states exhibit only relatively weak damping. Shorter wavelength modes exhibit a strong decay instability which can be experimentally controlled.
