Weakly nonlinear stationary spectra of long-wave low-frequency electromagnetic fluctuations in a colloidal plasma

The long-wave low-frequency electromagnetic excitations in a colloidal plasma with a dynamic recharging are investigated. In the weakly nonlinear regime, stationary spectra of thermal fluctuations are obtained. It is shown that in this case, the dynamic recharging makes a substantial contribution to the renormalized viscosity coefficient and gives rise to renormalized absorption frequency. For strong dynamic recharging, the anomalous diffusion is essentially decreased (with no Bohm-like behaviour) which may be of interest for the fusion problem.
