On the Normal State Electronic properties of Layered Sr_2 RuO_4
Abstract
Based on a comprehensive perusal of experimental results, we construct a microscopic model describing the normal state of layered 4d oxide Sr_2 RuO_4 incorporating relevant quantum chemical features of the material. The high-T anomalies are explained within a Luttinger liquid (LL) picture. Interlayer one-particle hopping drives a dimensional crossover to a correlated Fermi liquid below a scale E^{*} << t_{perp}. Using recently developed chain-dynamical mean field theory, the low value of E^{*}, as well as various puzzling features of the low-T normal state are explained as manifestations of the crossover from the high-T Luttinger liquid state in a consistent way.
