Simulations demonstrate that drift-wave turbulence spontaneously creates sheared E×B flows suppressing transport in diverted tokamak geometry, yielding first-principles scalings for L-H power thresholds, density minimum, and minimum power that match empirical data.

The L-H transition in tokamaks: power threshold, density minimum and toroidal-field asymmetry
Simulations demonstrate that drift-wave turbulence spontaneously creates sheared E×B flows suppressing transport in diverted tokamak geometry, yielding first-principles scalings for L-H power thresholds, density minimum, and minimum power that match empirical data.
