TL;DR
This study investigates how the superconducting gap in Bi2212 varies with doping, revealing that pairing susceptibility peaks at specific Fermi surface regions, influenced by feedback effects on the pairing boson.
Contribution
It provides new insights into the doping dependence of the superconducting gap and identifies shifted hot regions on the Fermi surface, challenging previous assumptions.
Findings
Pairing susceptibility peaks at specific Fermi surface regions.
Hot regions are centered away from nominal hot spots.
Feedback effects influence the pairing boson.
Abstract
The paper compares the K-dependence of the superconducting gap in different doping ranges. The fine behavior of the leading edge gap indicates that the pairing susceptibility is peaked at special regions on the Fermi surface. These hot regions are found to be centered away from nominal "hot spots". This behavior is attributed to a feedback effect on the pairing boson. Identification is made through comparison with neutron diffraction results.
