Visualization of plasma turbulence
IEEE Computer Graphics and Applications, 1995We have developed a three-dimensional toroidal gyrokinetic particle simulation to study tokamak turbulence. The gyrokinetic equations are a reduced set derived from the Vlasov-Maxwell equations by phase averaging over the ion gyromotion and keeping only the time and space scales relevant for describing tokamak plasmas.

Plasma Turbulent Bremsstrahlung
Physical Review Letters, 1994Plasma 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.

Barriers for Transport in Turbulent Plasmas
Physical Review Letters, 2003The control of transport due to electrostatic turbulence is investigated using test-particle simulations. We show that a barrier for the transport, that is, a region where transport is reduced, can be generated through the randomization of phases of the turbulent field.

INTERMITTENCY IN SPACE PLASMA TURBULENCE
2005We 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, 1993A 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.

Introduction to Turbulence in Magnetised Plasmas
AIP Conference Proceedings, 2005Turbulence is a complex manifestation of collective plasma behaviour. An introduction to turbulence with particular emphasis on magnetized plasmas is given. This chapter discusses the theoretical background to a leading edge topic in modern plasma physics it is understood to accompany the section on experimental transport studies (Chap. 9 in Part II).

Theory of Strong Turbulence in Plasmas
The Physics of Fluids, 1970A theory of fluctuations which may be applicable to a plasma in any of the three states, namely, the quiescent, weakly turbulent, and strongly turbulent states, is obtained from an exact solution of the second equation of the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy for the stationary values of the pair correlation function.

Resonant quasiparticles in plasma turbulence
Physical Review E, 2003A 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.

Development of the concepts of plasma turbulence
Uspekhi Fizicheskih Nauk, 1972The review is devoted to exposition of the physical principles on which the current ideas on plasma turbulence are based. A comparison is made of the results obtained in the theory of plasma turbulence and the turbulence of incompressible liquids. The basic physical differences between hydrodynamic and plasma turbulence are pointed out. It is shown how
