An overview of the physics of intrinsic torque is presented, with special emphasis on the
phenomenology of intrinsic toroidal rotation in tokamaks, its theoretical understanding, and …

Poloidal and toroidal rotation has been recognized to play an important role in heat transport
and magnetohydrodynamic (MHD) stability in tokamaks and helical systems. It is well known …

Recent results in the theory of turbulent momentum transport and the origins of intrinsic
rotation are summarized. Special attention is focused on aspects of momentum transport …

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 …

Toroidal momentum transport mechanisms are reviewed and put in a broader perspective.
The generation of a finite momentum flux is closely related to the breaking of symmetry …

In tokamaks, turbulent particle and toroidal momentum transport are both characterized by
the presence of off-diagonal contributions which play an essential role in establishing the …

This paper presents a novel, unified approach to the theory of turbulent transport of parallel
momentum by collisionless drift waves. The physics of resonant and nonresonant off …

The symmetry of a physical system strongly impacts on its properties. In toroidal plasmas,
the symmetry along a magnetic field line usually constrains the radial flux of parallel …

We report the results of the first experiments on the DIII-D tokamak to examine the
dependence of the transport and stability characteristics of ITER hybrid scenario plasmas on …

Global gyrokinetic simulations have revealed an important nonlinear flow generation
process due to the residual stress produced by electrostatic turbulence of ion temperature …
