Plasma Turbulent Bremsstrahlung

Physical Review Letters, 1994
Plasma turbulent bremsstrahlung is a radiation of high frequency plasma mode produced by the scattered electrons due to the effective turbulent collisions associated with low frequency fluctuations. It is found that the spontaneous emission term in the quasilinear effect is responsible for the mechanism.

Plasma Edge Turbulence

Physical Review Letters, 1983
Model mode-coupling equations for the resistive drift-wave instability are derived and numerically solved to study the properties of turbulence near a plasma edge. The wavenumber spectrum of the turbulence is found to exhibit an inverse cascade to form an isotropic, two-dimensional Kolmogorov spectrum, ${k}^{\ensuremath{-}3}$, in the large-wave-number ...

Parametric plasma turbulence

Physics Reports, 1986
Abstract We present the results of the main papers published during the last few years on the theory of parametric absorption of electromagnetic radiation energy in plasmas. We use the approach of weak Langmuir turbulence theory, since it can be asserted on the basis of the contents of the present paper that this approach is consistent with a wide ...

Plasma turbulent reactors

Annals of Physics, 1977
Abstract Similarity solutions are found for the evolution of the distribution functions of the radiation and relativistic electrons in a plasma turbulent reactor (PTR). These solutions have a “universal” power-law form which is shown to be analogous to the Kolmogorov spectrum for fluid turbulence and stable in the same sense.

INTERMITTENCY IN SPACE PLASMA TURBULENCE

2005
We present a short overview on theoretical aspects and observational findings about intermittency in solar wind MHD turbulence. This phenomenon, which became a remarkable topic in the past few years, is due to the fact that solar wind fluctuations are neither isotropic nor scale-invariant, two of the fundamental hypotheses at the basis of K41 ...

Scalar model for plasma turbulence

Physical Review E, 1993
A shell model is proposed to study the Hasegawa-Mima equation [Phys. Fluids 21, 87 (1978)] describing the electric-potential fluctuaitons in microturbulent plasmas. The simularities with two-dimensional hydrodynamic turbulence are discussed. Both the direct cascade of enstrophy and the reverse cascade of energy are investigated.

Resonant quasiparticles in plasma turbulence

Physical Review E, 2003
A general view is proposed on wave propagation in fluids and plasmas where the resonant interaction of monochromatic waves with quasiparticles is considered. A kinetic equation for quasiparticles is used to describe the broadband turbulence interacting with monochromatic waves.
