Abstract

High-resolution photoemission is used to study the electronic structure of the cuprate superconductor, Bi₂Sr₂CaCu₂O_{8 + δ}, as a function of hole doping and temperature. A kink observed in the band dispersion in the nodal line in the superconducting state is associated with coupling to a resonant mode observed in neutron scattering. From the measured real part of the self-energy it is possible to extract a coupling constant which is largest in the underdoped regime, then decreasing continuously into the overdoped regime.
