Effect of nonlinear electron Landau damping in collisionless drift-wave turbulence
Collisionless drift-wave turbulence is studied with numerical simulations in a three-dimensional sheared slab geometry. Nonlinear electron Landau damping associated with parallel trapping is found to substantially reduce the anomalous particle transport for low magnetic shear, whereas it plays a very weak role for higher shear. This result has implications for the construction of transcollisional Landau-fluid models for passing electrons in the edge of a tokamak.
