Abstract
Calculations within the self-consistent and conserving fluctuation-exchange approximation (FLEX) on the two-dimensional one-band Hubbard model with a bandstructure appropriate for YBa2Cu3O7-x are presented in the superconducting state. The d-wave order parameter opens much more rapidly below T-c than BCS behavior. The temperature dependence near T-c is studied in more detail and an explanation is provided. I show the resulting anisotropic quasiparticle damping rates and discuss also how well the FLEX-approximation can describe the high-T-c superconductors. (C) 1997 Elsevier Science Ltd
