Abstract

Based upon the newly proposed partial quantum statistics [T. Zhou, Solid State Commun. 115, 185 (2000)], some canonical physical properties of partially localized electron systems have been calculated. The calculated transport and superconducting properties of such systems are very different from those of Landau Fermi liquids, but display some striking similarities to the properties of high temperature superconductors and some other narrow band materials.
