This paper presents a review of multi-scale interactions between small-scale turbulence and
large scale magnetic islands. In finite beta plasmas, zonal flows are relatively weak, and …

Multiscale interaction between the magnetic island and turbulence has been demonstrated
through simultaneous two-dimensional measurements of turbulence and temperature and …

Magnetic islands are a ubiquitous feature of magnetically confined plasmas. They arise as
the result of plasma instabilities as well as externally imposed symmetry-breaking …

We present the first localized measurements of long and intermediate wavelength turbulent
density fluctuations (⁠ n ̃⁠) and long wavelength turbulent electron temperature fluctuations …

Neoclassical tearing modes have deleterious effects on plasma confinement and, if they
grow large enough, they can lead to discharge termination. Therefore, they impose a major …

The interaction between small scale turbulence (of the order of the ion Larmor radius) and
mesoscale magnetic islands is investigated within the gyrokinetic framework. Turbulence …

Plasma in the earth's magnetosphere is subjected to compression during geomagnetically
active periods and relaxation in subsequent quiet times. Repeated compression and …

We present a gyrokinetic analysis of the vortex flow evolution in a magnetic island in
collisionless tokamak plasmas. In a short term ω¯ D t< 1, where ω¯ D is the secular …

This is the first numerical simulation demonstrating that a macromagnetohydrodynamic
(macro-MHD) mode is excited as a result of multi-scale interaction in a quasi-steady …

The influence of a static magnetic island on the behaviour of the electrostatic turbulence in a
tokamak is investigated numerically employing global nonlinear gyrokinetic particle-in-cell …
