# A Unified Description of Cuprate and Iron Arsenide Superconductors

## TL;DR

This paper presents a unified theoretical framework for understanding both cuprate and iron-based superconductors, highlighting key differences in their orbital pairing mechanisms.

## Contribution

It introduces a unified description that constrains pairing symmetries and reveals fundamental differences in orbital pairing formfactors between the two superconductor classes.

## Key findings

- Magnetic structure constraints inform pairing symmetry.
- Orbital pairing formfactors differ fundamentally between cuprates and iron arsenides.
- Unified description links magnetic properties to superconducting pairing.

## Abstract

We propose a unified description of cuprate and iron-based superconductivity. Consistency with magnetic structure inferred from neutron scattering implies significant constraints on the symmetry of the pairing gap for the iron-based superconductors. We find that this unification requires the orbital pairing formfactors for the iron arsenides to differ fundamentally from those for cuprates at the microscopic level.
