Room-temperature superconductivity in 1D

TL;DR

This paper reviews the theoretical framework behind recent claims of room-temperature superconductivity along line defects in graphite, emphasizing the roles of strain-induced pairing, Josephson junction formation, and dimensional effects.

Contribution

It provides a comprehensive theoretical explanation for observed 1D room-temperature superconductivity in graphite surface defects, integrating strain effects and dimensional embedding.

Findings

Superconductivity arises from strain gauge field pairing.

Formation of Josephson junction arrays explains the Bose metal state.

Dimensional embedding suppresses phase slips, stabilizing superconductivity.

Abstract

We review the theoretical model underpinning the recently reported room-temperature, ambient-pressure superconductivity along line defects on the surface of highly-oriented pyrolytic graphite. The main ingredients for this 1D room-temperature superconductivity are pairing by effective strain gauge fields, the formation of an effective Josephson junction array in its Bose metal state on the surface and the suppression of phase slips by dimensional embedding in an extremely well-conducting 3D bulk structure.
