Inhomogeneous superconductivity and the "pseudogap state of novel superconductors

TL;DR

This paper discusses the inhomogeneous nature of novel superconductors like high Tc oxides, emphasizing how doping creates spatial variations in critical temperature and affects their superconducting properties.

Contribution

It introduces a framework to understand inhomogeneous superconductivity and the pseudogap state in doped high Tc oxides.

Findings

Doping leads to spatially varying critical temperatures.

Inhomogeneity influences the pseudogap behavior.

Superconducting properties are affected by dopant distribution.

Abstract

Novel superconducting compounds such as the high Tc oxides are intrinsically inhomogeneous systems. An inhomogeneous structure is created by doping and the statistical nature of the distribution of dopants. Consequently, the critical temperature is spatially dependent: Tc = Tc (r).
