Superconducting Gap Anisotropy and Quasiparticle Interactions: A Doping Dependent Photoemission Study
Open accessAbstract
Comparing photoemission measurements on Bi2212 with penetration depth data, we show that a description of the nodal excitations of the $d$-wave superconducting state in terms of noninteracting quasiparticles is inadequate, and we estimate the magnitude and doping dependence of the Landau interaction parameter which renormalizes the linear $T$ contribution to the superfluid density. Furthermore, although consistent with $d$-wave symmetry, the gap with underdoping cannot be fit by the simple $\mathrm{cos}{k}_{x}\ensuremath{-}\mathrm{cos}{k}_{y}$ form, which suggests an increasing importance of long range interactions as the insulator is approached.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
