The Euler–Poisson equations for a cold, collisionless plasma support ion-acoustic solitary waves. We prove that these waves are spectrally stable at low amplitude in one space-dimension and present numerical evidence that they destabilize at finite amplitude before they develop singularities. © 2002 Elsevier Science B.V.

The oblique propagation of arbitrary ion acoustic solitary waves (IASWs) in magnetized electron-positron-ion plasmas is investigated by employing Sagdeev pseudopotential approach. Ions are assumed to be adiabatic having anisotropic thermal pressure. Electrons and positrons considered isothermal, following Maxwellian distribution. In terms electrostatic potential, potential function obtained ana...

Obliquely propagating three-dimensional dust-acoustic periodic travelling waves (DAPTWs) in a magnetized dusty plasma composed of negatively charged inertial dust particles, trapped ions, and nonthermal fast electrons have been undertaken. In the model at hand, dynamic behaviors DAPTWs are governed by Schamel equation. The presence acoustic solitary (DASWs) is investigated via bifurcation analy...

Investigated in this thesis are the excitation and observation of Langmuir wave turbulence caused by the parametric decay instability (PDI) in high-frequency space plasma heating experiments conducted at the NSF/DoD High Frequency Active Auroral Research Program (HAARP) facility in Gakona, Alaska during the spring and summer of 2006. The PDI is the decay of an electromagnetic (EM) wave into an ...
