Theory of the Anomalous Metallic Phase in the High-T_c Cuprate Superconductors

Abstract

We present a unified view of the mechanism of the high-T_c cuprate superconductors. The high-T_c cuprate superconductors are characterized as a pseudo two-dimensional metal in the vicinity of the Mott insulator. We showed that strong antiferromagnetic and superconducting fluctuations interact with each other and they induce anomalous metallic properties and characteristic features of the phase diagram.
