Self-duality of the asymptotic relaxation states of fluids and plasmas
F. Spineanu, M. Vlad
The states of asymptotic relaxation of 2-dimensional fluids and plasma present a high degree of regularity and obey to the sinh-Poisson equation. We find that embedding the classic…
On the nature of intermittency in weakly dissipative systems
F. Spineanu, M. Vlad
We propose a new perspective on the intermittency in weakly dissipative systems. It is focused on the elementary (burst-like) event separating states with different properties. Thi…
Stochastic island generation and influence on the effective transport in stochastic magnetic fields
M. Vlad, F. Spineanu, J. H. Misguich +1
The transport of collisional particles in stochastic magnetic fields is studied using the decorrelation trajectory method. The nonlinear effect of stochastic generation of magnetic…
Fluctuation of the ambipolar equilibrium in magnetic perturbations
F. Spineanu, M. Vlad
We draw attention on the fast oscillatory deviations from the residual non-ambipolarity in the case where electrons are driven by strong magnetic perturbations.
Noble internal transport barriers and radial subdiffusion of toroidal magnetic lines
J. H. Misguich, J. D. Reuss, D. Constantinecu +5
Single trajectories of magnetic line motion indicate the persistence of a central protected plasma core, surrounded by a chaotic shell enclosed in a double-sided transport barrier…
Soliton self-modulation of the turbulence amplitude and plasma rotation
F. Spineanu, M. Vlad
The space-uniform amplitude envelope of the Ion Temperature Gradient driven turbulence is unstable to small perturbations and evolves to nonuniform, soliton-like modulated profiles…
