CROSSOVER BETWEEN LUTTINGER AND FERMI-LIQUID BEHAVIOR IN WEAKLY COUPLED METALLIC CHAINS
@article{Kopietz1997CROSSOVERBL, title={CROSSOVER BETWEEN LUTTINGER AND FERMI-LIQUID BEHAVIOR IN WEAKLY COUPLED METALLIC CHAINS}, author={Peter Kopietz and V Meden and Kurt Schoenhammer}, journal={Physical Review B}, year={1997}, volume={56}, pages={7232-7244} }
We use higher-dimensional bosonization to study the normal state of electrons in weakly coupled metallic chains interacting with long-range Coulomb forces. Particular attention is paid to the crossover between Luttinger and Fermi liquid behavior as the interchain hopping is varied. Although in the physically interesting case of finite but small interchain hopping the quasi-particle residue does not vanish, the single-particle Green's function exhibits the signature of Luttinger liquid behavior…

It is shown that a resonance state in the chain density of states is induced only by a magnetic impurity, and the spatial form of the resonance reflects the particle-hole nature of chain superconductivity and therefore distinguishes it from other broken symmetry phases.
