Title: Superconductor-to-metal transition in overdoped cuprates
ORAL · Invited
Abstract
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.
