Electrons, phonons, and their interaction in YBa2Cu3O7.

Andersen O.K., Liechtenstein A.I., Rodriguez O., Mazin I.I., Jepsen O., Antropov V.P., Gunnarsson O., Gopalan S.

The authors have performed LDA calculations of structure, phonon frequencies, and the electron-phonon interaction. They find good agreement with available data and estimate: lambda =1. Saddlepoints 20 meV below the Fermi level are important.
