On plasma diffusion in strong turbulence

It is shown that the velocity diffusivity of electrons in strong Langmuirtu rbulence is linearly proportional to the root-mean-square (rms) value ofthe electric field. The time-dependent diffusivity previously identified isa t ransient phenomenon. In 2-D spatial diffusion due to E x B velocityturbulen ce, time-dependent intermediate diffusivity emerges also followed bya well- behaved diffusivity proportional to the rms amplitude of the turbulentfield .
