Mechanism for the Nanoscale Condensate Disorder of Cuprates

ORAL

Abstract

Nanoscale electronic disorder has long remained a mystery in carrier-doped CuO2 superconductors. We combine scanned electron-pair (Josephson) and single-electron tunneling microscopy to visualize simultaneously the superconductive condensate electron-pair density nP(r) and the spectrum N(r) of single-electron quasiparticles in Bi2Sr2CaCu2O8. Motivated by (arXiv:2108.03655) our objective is to study and eventually explain the nanoscale disorder in nP(r), the singe-particle energy-gap Δ(r) and the superconductive coherence-peak height C(r).
