FROHLICH CONDUCTION IN SPIN-DENSITY WAVES

Making use of the anisotropic Hubbard model, we study the transport properties of spin-density waves (SDW) in organic conductors within mean-field theory. We show that the SDW in these systems exhibit the Fröhlich conduction. In particular, we obtain the phase Hamiltonian, which describes the phason dynamics in terms of microscopic parameters. We also analyze the microwave conductivity, the nonohmic conductivity, and the sound propagation in the SDW. © 1990 The American Physical Society.
