Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

Fusion energy is a promising source of clean energy, which could solve energy shortages
and environmental pollution. Research into controlled fusion energy has been ongoing for …

Direct evidence of zonal flow (ZF) predator-prey oscillations and the synergistic roles of ZF-
and equilibrium E× B flow shear in triggering the low-to high-confinement (L-to H-mode) …

A fast edge turbulence suppression event has been simulated in the electrostatic version of
the gyrokinetic particle-in-cell code XGC1 in a realistic diverted tokamak edge geometry …

Significant progress, on both the technological and physical fronts, towards high-
performance, long-pulse plasma discharges has been made in EAST (the experimental …

In this paper, recent progress on experimental analysis and theoretical models for non-local
transport (non-Fickian fluxes in real space) is reviewed. The non-locality in the heat and …

We investigate the dynamics of the low (L)→ high (H) transition using a time-dependent, one
dimensional (in radius) model which self-consistently describes the time evolution of zonal …

Magnetic confinement fusion offers the promise of sustainable and safe energy production
on Earth. Advanced experimental scenarios exploit the fascinating yet uncommon ability of …

The dynamic features of the low-intermediate–high-(LIH) confinement transitions on HL-2A
tokamak are presented. Here we report the discovery of two types of limit cycles (dubbed …

Transport barrier formation and its relation to sheared flows in fluids and plasmas are of
fundamental interest in various natural and laboratory observations and of critical …
