Kinetic analysis of spin current contribution to spectrum of electromagnetic waves in spin-1/2 plasma, Part I: Dielectric permeability tensor for magnetized plasmas

摘要

The dielectric permeability tensor for spin polarized plasmas is derived interms of the spin-1/2 quantum kinetic model in six-dimensional phase space.Expressions for the distribution function and spin distribution function arederived in linear approximations on the path of dielectric permeability tensorderivation. The dielectric permeability tensor is derived the spin-polarizeddegenerate electron gas. It is also discussed at the finite temperature regime,where the equilibrium distribution function is presented by the spin-polarizedFermi-Dirac distribution. Consideration of the spin-polarized equilibriumstates opens possibilities for the kinetic modeling of the thermal spin currentcontribution in the plasma dynamics.
