Low-frequency linear waves and instabilities in uniform and stratified plasmas:the role of kinetic effects
Low-frequency linear waves uniform and stratified plasmas kinetic effects

We review the basic approximations underlying magnetohydrodynamic (MHD) theory, with special emphasis on the closure approximations, i.e. the approximations used in any fluid approach to close the hie...
Nonlinear dynamics of turbulent waves in fluids and plasmas

In a model drift wave system that is interesting both in fluids and plasmas, we find that an embedded moving saddle point plays an important role at the onset of turbulence. Here the saddle point is a...

Non-propagating magnetic hole solutions in anisotropic plasmas near the mirror instability threshold are investigated in numerical simulations of a fluid model that incorporates linear Landau damping ...

Since the early 90s it was shown that Probability Distribution Functions (PDFs) of small scale differences (fluctuations) of several quantities in space plasmas display significant departures from Gau...

Phase-space electron holes are seen in simulations, laboratory plasmas, and many
regions of the Earth’s space environment. We present simulations of beam plasmas
showing that the generation and deca...
