Evidence for an Anti-polar Phase in Normal and Superconducting States in all HTSC

TL;DR

This paper presents evidence that high-temperature superconductors exhibit an anti-polar phase with long-range order, which is linked to the onset of superconductivity and influences their strong coupling and two-dimensional properties.

Contribution

It introduces the concept of an anti-polar phase in HTSC and argues its role in superconductivity and related properties.

Findings

Presence of anti-polar phase in normal and superconducting states

Anti-polar phase linked to superconductivity onset

Explains strong coupling and 2D characteristics of HTSC

Abstract

It is strongly argued that high temperature superconductors (HTSC) exhibit an anti-polar phase with a long range order in both normal and superconducting states. This anti-polar phase is directly related to the onset of superconductivity in all HTSC and it is responsible for strong coupling and of two dimensionality aspect of HTSC, as it is described below.
