Abstract
We demonstrate that the E vs k dispersion in the superconducting state extracted from momentum-distribution curves differs qualitatively from the traditional dispersion extracted from energy-distribution curves. This occurs because of a combination of many-body effects and the presence of an energy gap, along with the associated coherence factors. Analysis of such momentum-distribution-curve dispersions can give important information on the microscopics of high-temperature superconductors.
