Abstract
We have performed electronic structure calculations for the high T-c c ompound YBa2Cu3O7 With a 3% reduced unit-cell volume. The effect on ba nd structure and Fermi surface is investigated. The predominant featur es are van Hoove singularities at the Fermi level. Keeping the experim ental lattice parameters, nearly the same effects occur when replacing the local-density approximation by a generalized gradient correction scheme.
