Abstract
A one-dimensional electron system at quarter-filling has been examined by applying the renormalization group method to a bosonized model with on-site (U) and nearest-neighbor (V) repulsive interactions. By evaluating both normal scattering and Umklapp scattering perturbatively, we obtain a phase diagram in which a metallic state with a 2kF spin density wave (kF is the Fermi wave number) moves into an insulating state with charge disproportionation of a 4kF charge density wave with an increase in both U and V. The effect of the next-nearest-neighbor repulsion is also discussed.
