Anomaly at Delta_k in the ARPES spectrum of dirty superconductors
arXiv:cond-mat/0410689 · doi:10.1103/PhysRevB.71.212501
Abstract
Elastic forward scattering can lead to an anomaly in the ARPES spectrum of the cuprate superconductors. Here we discuss how this anomaly can be used to provide a measurement of the superconducting gap Delta_k for k values away from the Fermi surface.
