Collisionless Dissipative Nonlinear Alfven Waves: Nonlinear Steepening, Compressible Turbulence, and Particle Trapping
M. V. Medvedev
The magnetic energy of nonlinear Alfven waves in compressible plasmas may be ponderomotively coupled only to ion-acoustic quasi-modes which modulate the wave phase velocity and cau…
Self-Organized States in Cellular Automata: Exact Solution
M. V. Medvedev, P. H. Diamond
The spatial structure, fluctuations as well as all state probabilities of self-organized (steady) states of cellular automata can be found (almost) exactly and {\em explicitly} fro…
Dissipative Dynamics of Collisionless Nonlinear Alfven Wave Trains
M. V. Medvedev, P. H. Diamond, V. I. Shevchenko +1
The nonlinear dynamics of collisionless Alfven trains, including resonant particle effects is studied using the kinetic nonlinear Schroedinger (KNLS) equation model. Numerical solu…
Fluid Models for Kinetic Effects on Coherent Nonlinear Alfven Waves. II. Numerical Solutions
M. V. Medvedev, V. I. Shevchenko, P. H. Diamond +1
The influence of various kinetic effects (e.g. Landau damping, diffusive and collisional dissipation, and finite Larmor radius terms) on the nonlinear evolution of finite amplitude…
