Fig. 4
Perpendicular field line diffusion coefficient, κFL, for isotropic Alfvénic turbulence. In panel a) linear polarized Alfvén waves with vanishing cross helicity were used; hence the turbulence is axisymmetric. In panel b) circular polarized Alfvén waves were used that are all of the same handedness so that the magnetic helicity is maximal. The colors are the same as in Fig. 2.
