A Landau fluid model for a collisionless electron-proton magnetized plasma, that accurately reproduces the dispersion relation and the Landau damping rate of all the magnetohydrodynamic waves, is presented. It is obtained by an accurate closure of the hydrodynamic hierarchy at the level of the fourth order moments, based on linear kinetic theory. It retains non-gyrotropic corrections to the pre...

We study the effect of unlinearized medium on the collective excitations in quarkgluon plasma. We present two kinds of non-Abelian oscillation solutions which respectively correspond to weakly and strongly nonlinear coupling of field components in color space. We also show that the weakly nonlinear solution is similar to Abelianlike one but has the frequency shift, which is of order gT , from e...

We investigate transverse symmetry-breaking instabilities emerging from the optomechanical coupling between light and the translational degrees of freedom of a collisionless, damping-free gas of cold, two-level atoms. We develop a kinetic theory that can also be mapped on to the case of an electron plasma under ponderomotive forces. A general criterion for the existence and spatial scale of tra...

We investigate rescaling transformations for the Vlasov-Poisson and Euler-Poisson systems and derive in the plasma physics case Lyapunov functionals which can be used to analyze dispersion effects. The method is also used for studying the long time behaviour of the solutions and can be applied to other models in kinetic theory (2-dimensional symmetric Vlasov-Poisson system with an external magn...

Collisionless plasma expansion is a fundamental physics problem in plasma science and has great impacts on engineering applications, such as fusion and electric propulsion. Though much more computationally expensive, the kinetic approaches are required for both electrons and ions in order to accurately solve the collisionless plasma problems. The gridbased direct kinetic simulation code with GP...

A kinetic theory of linear electrostatic plasma waves with frequencies near the cyclotron frequency Ωcs of a given plasma species s is developed for a multispecies nonneutral plasma column with general radial density and electric field profiles. Terms in the perturbed distribution function up to O(1/Ωcs) are kept, as are the effects of finite cyclotron radius rc up to O(r 2 c ). At this order t...

We present a theoretical model that allows a fast and accurate evaluation of ionic transport properties of realistic plasmas spanning from warm and dense to hot and dilute conditions, including mixtures. This is achieved by combining a recent kinetic theory based on effective interaction potentials with a model for the equilibrium radial density distribution based on an average atom model and t...

Within classical transport theory, an approach is presented to derive systematically effective collision terms and noise sources for effective kinetic equations of nonAbelian plasmas. This procedure amounts to the ‘integrating-out’ of fluctuations, and is applicable for inand out-of-equilibrium situations. When applied to a hot non-Abelian plasma close to equilibrium we recover the collision in...

Context. Spacecraft measurements have shown Kinetic Alfv\'en Waves propagating in the terrestrial magnetosphere at lower wavenormal angles than predicted by linear Vlasov theory of electron-proton plasmas. To explain these observations, it has been suggested that abundant heavy ion populations this region may strong, non-trivial effects allow Alfv\'enic waves to acquire right-handed polarizatio...
