Ion-beam-plasma electromagnetic instabilities
(Cambridge Univ Press, 2000)
It is well known that ion-beam-plasma interactions can destabilize right- and left-hand polarized electromagnetic waves. Owing to the fact that these instabilities have mostly been studied numerically by solving the ...
Dust-induced instability in a rotating plasma
(AMER INST PHYSICS, 2008)
The effect of immobile dust on stability of a magnetized rotating plasma is analyzed. In the presence of dust, a term containing an electric field appears in the one-fluid equation of plasma motion. This electric field ...
New parametric decays of proton beam-plasma electromagnetic waves
(Blackwell Publishing Ltd, 2002)
Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
Pic simulations of the effect of velocity space instabilities on electron viscosity and thermal conduction
(IOP Publishing, 2016)
In low-collisionality plasmas, velocity-space instabilities are a key mechanism providing an effective collisionality for the plasma. We use particle-in-cell (PIC) simulations to study the interplay between electron-and ...
Electromagnetic ion-beam instabilities in a cold plasma
(1996)
We study the stability of the cold-plasma dispersion relation for circularly polarized waves in a plasma composed of an ion background and an ion beam. The presence of the beam introduces a resonant branch into the dispersion ...
Three‐dimensional numerical simulation of equatorial F region plasma irregularities with bottomside shear flow
(American Geophysical Union, 2010-11-20)
A three‐dimensional numerical simulation of plasma density irregularities in the postsunset equatorial F region ionosphere leading to equatorial spread F (ESF) is described. The simulation advances the plasma number density ...
Role of the Hall effect on the magnetorotational instability
(World Scientific, 2010-06)
Within the framework of magnetohydrodynamics, the Hall effect might become nonnegligible either in fully ionized low density plasmas or in cold plasmas with a low ionization fraction . We address the role of the Hall current ...
PIC simulations of velocity space instabilities in a decreasing magnetic field: viscosity and thermal conduction
(IOP Publishing Ltd, 2018)
We use particle-in-cell (PIC) simulations of a collisionless, electron-ion plasma with a decreasing background magnetic field, B, to study the effect of velocity-space instabilities on the viscous heating and thermal ...
