Eversus k Relations and Many Body Effects in the Model Insulating Copper OxideSr2CuO2Cl2
Abstract
We report angle resolved photoemission measurements on ${\mathrm{Sr}}_{2}$Cu${\mathrm{O}}_{2}$${\mathrm{Cl}}_{2}$, an insulating layered copper oxide. We find that the overall width of the highest occupied band and the position of the band maximum at ($\frac{\ensuremath{\pi}}{2}, \frac{\ensuremath{\pi}}{2}$) agree with predictions of the $t\ensuremath{-}J$ model and other calculations based on the Hubbard model. However, in many regions of the Brillouin zone, the shape of the band differs from these predictions. A comparison of our data with spectra previously reported on metallic samples leads to new suggestions for the phenomenology of doping.

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.
