摘要：
The self-energy of q = 0 phonons is calculated in both the superconducting and normal states, with use of a real-axis formulation, valid for arbitrary temperature, impurity scattering rate, and electron-phonon coupling strength. The calculations are performed within the Eliashberg framework. We qualitatively confirm much of the previous work done using Pade approximants. Besides providing quantitative corrections, we also predict an observable effect with low-frequency phonons.
