Figure 3.

Simulation for a single coupling mode at Ω = 40 meV. Dotted and solid curves denote those with and without a d-wave gap of Δ = 30 meV, respectively. (a) Diagram of electron-boson interaction. (b) Eliashberg coupling function α2F(-ω), dispersion k(ω) = [ω + ReΣ(ω)]/v0, and momentum width Δk(ω) = -ImΣ(ω)/v0. (c) Real and imaginary parts of 1 + λ(ω).
