- Abstract
The problem of constructing the kinetic equation with the description of motion of a hole in systems with strong spin-hole interaction (such as high-temperature superconductors) in terms of the spin polaron has been considered in the framework of the regular antiferromagnetic s-d model. It has been shown by the example of electrical resistivity that the kinetics is determined by the properties of the bands of the spin polariton (rather than “bar hole”) and their quasiparticle residues Z k. The cases of low and optimal doping of the CuO2 plane have been considered. It has been shown that the rearrangement of the spectrum of the lower polaron band, as well as the strong doping dependence of the quasiparticle residues Z k, is decisive in the unified consideration of these cases.
