摘要: We consider a two-dimensional model of the pseudogap state, based on scenario strong electron scattering by fluctuations ``dielectric'' (AFM, CDW) short-range order. construct system recurrence equations both for one-particle Green's function and vertex part, describing interaction with an external field, which take into account all Feynman graphs order fluctuations. The results detailed calculations optical conductivity are presented different geometries (topologies) Fermi surface, demonstrating effects formation localization effects. These in qualitative agreement experimental data obtained high-temperature superconducting cuprates.
