| Abstract: | The vortex structures for the short-length drift Alfven waves in magnetized plasmas are investigated.The turbulence spectra of Plasma vortex are estimated,and the anomalous diffusion coefficient is found using the dynamic model of plasma gas. The results show that the anomalous diffusion coefficient caused by the vortex turbulence is proportional to the square of the potential amplitude of the perturbation. |
