Neutral Vlasov kinetic theory of magnetized plasmas
Abstract
The lowfrequency limit of Maxwell equations is considered in the MaxwellVlasov system. This limit produces a neutral Vlasov system that captures essential features of plasma dynamics, while neglecting radiation effects. EulerPoincaré reduction theory is used to show that the neutral Vlasov kinetic theory possesses a variational formulation in both Lagrangian and Eulerian coordinates. By construction, the new model recovers all collisionless neutral models employed in plasma simulations. Then, comparisons between the neutral Vlasov system and hybrid kineticfluid models are presented in the linear regime.

Kinetic theory of stimulated Raman sidescattering from magnetized plasmas
A theory of stimulated Raman sidescattering in magnetized plasmas is presented based on a solution of the VlasovMaxwell equations. The incident laser light, in the form of extraordinary mode radiation, decays into light waves which propagate along the uniform magnetic field as right or left circularly polarized waves. The scattered plasma mode is an obliquely propagating electronBernstein wave. The possible relevance of the theory to experiments in which structure is observed in radiation at onehalf of the laser frequency is discussed. 
Kinetic theory of ion collection by probing objects in flowing strongly magnetized plasmas
A new onedimensional collisionless kinetic model is developed for the flow of ions to probing structures in drifting plasmas. The crossfield flow into the presheath is modeled by accounting consistently for particle exchange between the collection flux tube and the outer plasma. Numerical solutions of the selfconsistent plasmasheath equations are obtained with arbitrary external ion temperature and parallel plasma flow velocity. Results are presented of the spatial dependence of the ion distribution function as well as its moments (density, particle flux, temperature, and power flux). The ion current to the probe is obtained and the ratio of the upstream tomore » 
Covariant kinetic dispersion theory of linear transverse waves parallel propagating in magnetized plasmas with thermal anisotropy
The properties of transverse waves parallel propagating in magnetized plasmas with arbitrary composition and thermally anisotropic, are investigated on the basis of relativistic VlasovMaxwell equations. The transverse dispersion relations for plasmas with arbitrary distribution functions are derived. These dispersion relations describe the linear response of the system to the initial perturbations and thus define all existing linear (transverse) plasma modes in the system. By analytic continuation the dispersion relations in the whole complex frequency plane are constructed. Further analysis is restricted to the important case of anisotropic biMaxwellian equilibrium plasma distribution functions. Explicit forms of the relativistically correct transverse dispersionmore »
