The electrons of the system of conducting linear chains with lattice parameters d∥ and d⊥ are assumed to interact through the long-range Coulomb forces. Assuming further that the ratio ν of the first-neighbour Coulomb interaction e2/d∥ to the band-width is small, the problem is treated in the parquet approximation. The parquet diagrams are evaluated using the non-logarithmically screened Coulomb interaction for the forward scattering and the bare Coulomb interaction for the backward scattering. The weak interchain backward scattering is neglected. The parquet approximation eliminates then the screened interchain forward scattering. The three-dimensionality enters the results through the screening of the on-chain forward interaction. This sc...
