LUTTINGER THEOREM IN ONE-DIMENSIONAL METALS

One dimensional metals are described by Luttinger liquid theory. Recen t experiments have addressed the relation between this non-Fermi liqui d behavior and the existence of a Fermi surface. We show that Luttinge r's theorem, with few modifications, holds for the one dimensional Tom onaga-Luttinger model. The implications for the high temperature super conductors are discussed.
