Cu, Pu and Fe high Tc superconductors: all the same mechanism!

TL;DR

This paper proposes a unified mechanism involving spin holes and bipolarons to explain high-temperature superconductivity in Cu, Pu, and Fe-based materials, challenging traditional BCS theory.

Contribution

It introduces a novel theory that high Tc superconductivity arises from bipolarons formed by spin holes in antiferromagnetic clusters.

Findings

Spin holes form nonmagnetic bipolarons.

Bipolarons condense to produce superconductivity.

Unified explanation for Cu, Pu, and Fe high Tc superconductors.

Abstract

The new iron based high Tc superconductors with Tc up to 55 K have stirred new interest in this field. It is consensus that the BCS mechanism is not able to explain the high Tc's. In the following we propose that spin holes in antiferromagnetic clusters combine to make nonmagnetic bipolarons, which can condense and lead to superconductivity.
