Implications evinced by the phase diagram, anisotropy, magnetic penetration depths, isotope effects and conductivities of cuprate superconductors

TL;DR

This paper reviews how anisotropy, penetration depths, isotope effects, and conductivities in cuprate superconductors vary with doping, providing insights into their microscopic mechanisms and universal behaviors.

Contribution

It offers a comprehensive reassessment of the doping dependence of key physical properties in cuprates, linking them to superconductivity mechanisms.

Findings

Anisotropy and fluctuations depend on dopant concentration.

Doping influences transition temperature and penetration depths.

Universal behaviors emerge from the doping dependence of properties.

Abstract

Anisotropy, thermal and quantum fluctuations and their dependence on dopant concentration appear to be present in all cuprate superconductors, interwoven with the microscopic mechanisms responsible for superconductivity. Here we review anisotropy, in-plane and c-axis penetration depths, isotope effect and conductivity measurements to reassess the universal behavior of cuprates as revealed by the doping dependence of these phenomena and of the transition temperature.
