Spinon Superconductivity and Superconductivities Mediated by Spin-Waves and Phonons in Cuprates

TL;DR

This paper explores unconventional superconductivity mechanisms in cuprates, focusing on spinon and spin-wave mediated pairing, and discusses implications for different doping types and materials.

Contribution

It introduces the concept of spinon superconductivity and spin-wave mediated pairing as potential mechanisms in cuprates, expanding understanding beyond traditional phonon-based theories.

Findings

Spinon superconductivity proposed as a mechanism in cuprates.

Superconductivity mediated by spin-waves and phonons analyzed.

Implications for both hole-doped and electron-doped cuprates discussed.

Abstract

The disclosure of spinon superconductivity and superconductivity mediated by spin-waves in hole-doped Bi2212 cuprate raises the question about the origin of the superconductivity in other cuprates and specially in an electron-doped NCCO cuprate.
