An Ion Acoustic Wave refers to a type of wave in a plasma that can be used to accurately measure electron and ion temperatures, electron density, plasma flow, and relative electron-ion drive velocity. AI generated definition based on: Plasma Scattering of Electromagnetic Radiation (Second Edition...
We study the evolution of Langmuir waves coupled to the ion acoustic wave by means of the ponderomotive force in the Karpman limit (caviton equation). Using the spectral transform with singular dispersion relation, it is shown that the background noise (fluctuations in the ion density) is ...
The dispersion relation for ion acoustic wave re- veal the existence of two modes fast and slow if the stream- ing speed of ions is tacked into account. The Sagdeev pseu- dopotential method was used to investigate the allowed do- main of velocity of ion acoustic soliton. It is found ...
By employing standard normal-mode analysis the dispersion relation for linear waves is studied. The numerical results are presented to understand the features of ion acoustic solitary wave structures. It is shown that the present plasma model supports IASWs having positive potential well. Also, it ...
It is well known that the presence of negatively charged dust particles causes the phase velocity (ω/k) of the ion acoustic wave to increase which is also associated with the Landau damping of the wave becoming less severe due to the dust particles. A linear dispersion relation of the dust...
Coupled wave equations have been developed for the propagation of electromagnetic, electron acoustic and ion acoustic waves in a homogeneous, warm magnetoplasma employing the linearized two-fluid continuum theory of partially ionized plasma dynamics. For the purpose of this study propagation is considered...

The author examined the evolution of electrons and contribution of magnetic field in the Langmuir wave dispersion via the different occupation of spin-up and spin-down states. The existence of spin-electron-positron acoustic spin-electron acoustic, and positron acoustic solitons in degenerate electron-...
