We use higher-dimensional bosonization to study the normal state of electronsin weakly coupled metallic chains interacting with long-range Coulomb forces.Particular attention is paid to the crossover between Luttinger and Fermiliquid behavior as the interchain hopping is varied. Although in the physicallyinteresting case of finite but small interchain hopping the quasi-particleresidue does not vanish, the single-particle Green's function exhibits thesignature of Luttinger liquid behavior (i.e. anomalous scaling and spin-chargeseparation) in a large intermediate parameter regime. Using realisticparameters, we find that the scaling behavior in this regime is characterizedby an anomalous dimension of the order of unity, as suggested by recentexperiments on quasi-one-dimensional conductors. Our calculation gives newinsights into the approximations inherent in higher-dimensional bosonization.We also compare our approach with other methods.Comment: RevTex, 8 figures, submitted to Phys.
