The present status of zonal flow experiments is reviewed with the historical process to attain
the concept of zonal flows, which provides a new framework for understanding turbulence …

The goal of this review is to outline some unconventional ideas behind new paradigms in
the modern theory of turbulence. Application of nonstandard, topological methods to …

Fractional Fokker–Planck equation is proposed for the kinetic description of relaxation and
superdiffusion processes in constant magnetic and random electric fields. It is assumed that …

The article reports on recent developments in the theory of secondary instability in drift-ion
temperature gradient turbulence. Specifically, the article explores secondary instability as a …

A unique parabolic relation is observed to link skewness and kurtosis of around ten
thousand density fluctuation signals, measured over the whole cross section of a toroidal …

The high plasma temperatures expected at reactor conditions in magnetic confinement
fusion toroidal devices suggest that near-marginal operation could be a reality in future …

Transport in fusion plasmas in the low confinement mode is characterized by several
remarkable properties: the anomalous scaling of transport with system size, stiff (or …

A new set of distributions, called fractional stable distributions, is described. A subset of this
set is represented by stable laws, while its particular case is the Gaussian distribution. These …

Flux-driven ion temperature gradient (ITG) turbulence and associated transport regulated by
non-local and non-diffusive processes are investigated based on GKNET simulations in a …

This review presents experimental studies on improved confinement (IC) modes observed
mainly in stellarator plasmas. The IC modes result from structural bifurcation, often …
