Self-interaction-free density-functional band theory for magnetic cuprates

We overview the capability of the pseudo-SIC -a self-interaction-free density-functional approach- to explore the electronic and magnetic properties of cuprates. We consider the relevant test cases of CuO, GeCuO3, and YBa2Cu3O6, and give evidence that this approach provides a description in qualitatively improved agreement with the experiments.
