High-temperature superconductors: divine malevolence.

Summary

Eight years after their discovery, the high-transition-temperature cuprate superconductors are still poorly understood. But at a recent conference in Stanford, spectroscopists and theorists mostly agreed on one previously contentious issue: the energy gap in the electronic spectrum, at least for the highest-transition-temperature systems, has "nodes" at which the excitation energy goes to zero. Another big issue where quarrels are gradually being resolved is that the connection between the superconducting cuprates and the insulating antiferromagnetic cuprates, which are crystallographically almost identical, is becoming clearer.
