Abstract
The nonlinear interaction between the edge low-frequency electromagnetic plasma excitations is studied on the basis of the cross-field renormalized statistical approach. It is found that the longitudinal external electric field and the external current parallel gradient can substantially change the stationary spectra of electromagnetic excitations in a plasma. The cross correlation spectrum being induced by the external current in the linear approximation, may be strongly affected by the nonlinear mode interaction. The magnetic drift is manifested in attenuation of anomalous diffusion, whereas the net effect of the cross-field correlations is to enhance the anomalous transport. The particle diffusion is decreased by the transverse part of the external electric field.
