Resonance Broadening Induced Nonlinear Saturation of Kinetic Alfven Turbulence in the Interplanetary Plasma
M. V. Medvedev, P. H. Diamond
The saturation of ion cyclotron Alfven turbulence excited by beam particles is investigated using resonance broadening theory. The stochastic scattering which decorrelates particle…
Fluid Models for Kinetic Effects on Coherent Nonlinear Alfven Waves. I. Fundamental Theory
M. V. Medvedev, P. H. Diamond
Collisionless regime kinetic models for coherent nonlinear Alfven wave dynamics are studied using fluid moment equations with an approximate closure anzatz. Resonant particle effec…
Towards a Simple Model of Compressible Alfvenic Turbulence
M. V. Medvedev, P. H. Diamond
A simple model collisionless, dissipative, compressible MHD (Alfvenic) turbulence in a magnetized system is investigated. In contrast to more familiar paradigms of turbulence, diss…
Properties of Particles Obeying Ambiguous Statistics
M. V. Medvedev
A new class of identical particles which may exhibit both Bose and Fermi statistics with respective probabilities and is introduced. Such an uncertainity may be either…
