Recent experimental and simulation work has substantially advanced the understanding of
L-mode plasma edge turbulence and plasma flows and their mutual interaction across the L …

The general aspects of zonal flow physics, their formation, damping and interplay with quasi
two dimensional turbulence are explained in the context of magnetized plasmas and quasi …

Electric field profile structure—especially its shear—is a natural order parameter for the edge
plasma, and characterizes confinement regimes ranging from the H-mode (Wagner et al …

The turbulence and flows at the plasma edge during the L–I–H, L–I–L and single-step L–H
transitions have been measured directly using two reciprocating Langmuir probe systems at …

We present a gyrokinetic theory of self-generated E× B vortex flows in a magnetic island in a
collisionless tokamak plasma with a background vortex flow. We find that the long-term …

We present direct evidence of low frequency, radially sheared, turbulence-driven flows
(zonal flows (ZFs)) triggering edge transport barrier formation preceding the L-to H-mode …

We present a gyrokinetic theory of an E× B vortex flow in a magnetic island self-generated
from turbulence in a collisionless tokamak plasma. We have found that after fast collisionless …

The high-dimensional and multiscale nature of fusion plasma flows require the development
of reduced models to be implemented in numerical codes capable of capturing the main …

Abstract Understanding the L→ H and H→ L transitions is crucial to successful ITER
operation. In this paper we present novel theoretical and modelling study results on the …

This paper studies effects of q-profile structure on turbulence spreading. It reports results of
numerical experiments using global gyrokinetic simulations. We examine propagation of …
