Abstract

Renormalization group methods are applied to a set of coupled linear chains in a model in which direct hopping between chains is excluded. Attention is focused on models in which intrachain interactions are repulsive. It is shown first for two chains and then for N chains that a repulsive δ-function intrachain interaction scales with decreasing temperature to the attractive fixed point. In the N-chain model this attractive fixed point is characterized by a charge density wave whose phase is coherent between chains. A variety of response functions, spin and charge density waves at wave vector 2k r (k F is the Fermi wave vector), the uniform magnetic susceptibility, excitonic response functions, and 4kF response functions are calculated numerically. A comparison is made to the behavior of TTF-TCNQ (tetrathiafulvalene-tetracyanoquinodimethane) at temperatures above 60 K.
