Findings

Fe-pnictide and cuprate superconductors may share similar pairing mechanisms

The 2-leg ladder model captures essential features of Fe-pnictide superconductors

The relationship between Fe-pnictides and cuprates is elucidated through the model

Abstract

We construct a 2-leg ladder model of an Fe-pnictide superconductor and discuss its properties and relationship with the familiar 2-leg cuprate model. Our results suggest that the underlying pairing mechanism for the Fe-pnictide superconductors is similar to that for the cuprates.
