Nonlocal Electron Transport in a Plasma

Abstract

We have developed a nonlocal linear theory of electron transport in plasmas with arbitrary electron collisionality. Closure relations for the fluid equations are derived from a solution to the electron Fokker-Planck equation where electron collisions are considered in the limit of large ion charge. We have found nonlocal expressions for electron transport coefficients: the electric conductivity, thermoelectric coefficient, thermal conductivity, electron viscosity, friction, and new transport coefficients related to the ion flow.
