Neutron resonance:: Modeling photoemission and tunneling data in the superconducting state of Bi2Sr2CaCu2O8+δ

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+delta We not only can explain the peak-dip-hump structure observed near the (pi, 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.
