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 …

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 …

Observations in the ASDEX Upgrade tokamak show a correlation between the gradient of
the intrinsic toroidal rotation profile and the logarithmic gradient of the electron density …

Turbulent transport of toroidal momentum is investigated in global linear gyrokinetic
simulations. The poloidal tilt of the global mode structure arising from the radial variation of …

The formation of the equilibrium radial electric field (Er) has been studied experimentally at
ASDEX Upgrade (AUG) in L-modes of “favorable”(ion∇ B-drift toward primary X-point) and …

The ASDEX Upgrade intrinsic rotation database has been expanded to include a large
number of measurements from ohmic L-mode discharges covering a wide range of plasma …

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 …

A novel mechanism for driving residual stress in tokamak plasmas based on k∥ symmetry
breaking by the turbulence intensity gradient is proposed. The physics of this mechanism is …
