Phys. Rev. Lett. 85, 3261–3264 (2000)Neutron Resonance: Modeling Photoemission and Tunneling Data in the Superconducting State of Bi2Sr2CaCu2O8+δReceived 24 May 2000; published in the issue dated 9 October 2000 Motivated by neutron scattering data, we develop a model of electrons interacting with a magnetic resonance and use it to analyze angle resolved photoemission and tunneling data in the superconducting state of Bi2Sr2CaCu2O8+δ. We not only can explain the peak-dip-hump structure observed near the (π,0) point, and its particle-hole asymmetry as seen in superconductor-insulator-normal tunneling spectra, but also its evolution throughout the Brillouin zone, including a velocity “kink” near the d-wave node. © 2000 The American Physical Society URL:
