Electric Conductivity of Weakly Turbulent Plasmas

The static electric conductivity of weakly turbulent plasmas has been examined on the basis of a kinetic equation for the linear response to the one-particle distribution function. Within the regime of neglecting the mode-coupling terms, the high-frequency turbulent fluctuations associated with the electron plasma wave give rise to a modification of the ordinary collisional conductivity through the adiabatic interaction between the particles and the turbulent fluctuations. On the other hand, the low-frequency turbulent fluctuation due to the ion oscillation mode determines the relaxation process in the system through the resonant interaction, and gives rise to a finite conductivity even in the collisionless plasmas.
