Antiferromagnetic Correlation and the Pairing Mechanism of the Cuprates and Iron Pnictides : a View From the Functional Renormalization Group Studies

TL;DR

This paper compares the functional renormalization group results for cuprates and iron pnictides, revealing that antiferromagnetic correlations likely drive pairing mechanisms in both types of high-temperature superconductors.

Contribution

It provides a unified view showing that antiferromagnetic correlations are a common pairing mechanism in cuprates and iron pnictides based on one-loop FRG analysis.

Findings

Antiferromagnetic correlations are linked to pairing in both materials.

A coherent picture of pairing mechanisms emerges from FRG results.

The study suggests a universal pairing mechanism driven by magnetic correlations.

Abstract

We compare the one-loop functional renormalization group results for the cuprates and the iron pnictides. Interestingly a coherent picture suggesting that antiferromagnetic correlation causes pairing for both materials emerges.
