Superconductor-to-metal transition in overdoped cuprates

We present a theoretical framework for understanding the behavior of the normal and superconducting states of overdoped cuprate high temperature superconductors in the vicinity of the doping-tuned quantum superconductor-to-metal transition. The key ingredients on which we focus are d-wave pairing, a flat antinodal dispersion, and disorder. Even for homogeneous disorder, these lead to effectively granular superconducting correlations and a superconducting transition temperature determined in large part by the superfluid stiffness rather than the pairing scale.

This paper presents a theoretical framework for understanding the behavior of overdoped cuprate high temperature superconductors, focusing on d-wave pairing, flat antinodal dispersion, and disorder. Even with homogeneous disorder, these factors lead to granular superconducting correlations and a transition temperature determined largely by the superfluid stiffness rather than the pairing scale.
