Electrostatic Structures in Space Plasmas: Stability of Two-dimensional Magnetic Bernstein-Greene-Kruskal Modes
Electrostatic structures, BGK modes, Solitons, Plasma kinetic equations
2011/9/5
Electrostatic structures have been observed in many regions of space plasmas, including the solar wind, the magnetosphere, the auroral acceleration region, and in association with shocks, turbulence, ...
Dromion solutions for nonlinear electron acoustic waves in space plasmas
Dromion solutions nonlinear electron acoustic waves space plasmas

Recent high resolution measurements of POLAR and FAST satellites have revealed two-dimensional coherent structures in the polar cap boundary layer (PCBL) region. Since the ion temperature is often obs...
Solitons and oscillitons in multi-ion space plasmas
Solitons oscillitons multi-ion space plasmas
2009/11/11
It is well known that additional low-frequency waves arise when a second ion population is added to a plasma normally consisting of protons and electrons. Here, we investigate stationary structures st...
Excitation of kinetic Alfvén turbulence by MHD waves and energization of space plasmas
kinetic Alfvén turbulence MHD waves energization of space plasmas
2009/11/11
There is abundant observational evidence that the energization of plasma particles in space is correlated with an enhanced activity of large-scale MHD waves. Since these waves cannot interact with par...

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...
