Drift waves in a cylindrical plasma column with an exponential density profile have a Bessel function mode structure and are linearly unstable because of finite Larmor radius effects. In the presence of a lower hybrid eigenmode pump, these modes suffer a nonlinear frequency upshift because of...

Electrostatic properties of density gradient drift waves (the universal mode) in a sheared magnetic field are studied using a two-and-one-half dimensional (2Â½-D) particle code. For the case of a single rational surface, the drift waves are found to be stable with an eigenmode structure that...

The excitation of electrostatic wakefields in a magnetized spin quantum plasma by the classical and the spin-induced ponderomotive force (CPF and SPF, respectively) due to whistler waves is reported. The nonlinear dynamics of the whistlers and the wakefields is shown to be governed by a coupled...
