A Common Thread

Abstract

The structures, the phase diagrams, and the appearance of a neutron resonance in the superconducting state provide phenomenological evidence which relate the heavy fermion, cuprate and Fe superconductors. Single- and multi-band Hubbard models have been found to describe a number of the observed properties of these materials so that it is reasonable to examine the origin of the pairing interaction in these models. Here based on the experimental phenomenology and studies of the momentum and frequency dependence of the pairing interaction for Hubbard-like models, we suggest that spin-fluctuation mediated pairing is the common thread linking this broad class of superconducting materials.

This work arose from an invitation to present an overview regarding "the mechanism of high temperature superconductivity including the cuprates and Fe- pnictides" at the 9th International Conference on Materials and Mechanisms of Superconductivity held in Tokyo (September 7-12, 2009)
