Superconductors carry electricity without resistance, but most only work a few degrees above absolute zero. In the late 1980s, copper-based materials called cuprates were found to superconduct at higher temperatures—reachable with affordable liquid nitrogen. Yet nearly 40 years later, physicists still don’t agree on why.
In a recent Science study, a team of physicists led by Milan Allan of Ludwig Maximilian University of Munich and Ingmar Swart of Utrecht University in the Netherlands has found some answers by listening to the faint electrical crackle of current flowing into a cuprate.
The missing electrons
Central to the mystery of cuprates’ high-temperature superconductivity is a strange state called the pseudogap. “The pseudogap is a phenomenon of missing electrons,” Allan said. Above the temperature at which cuprates become superconducting, some of their electrons seem to vanish—measurements find far fewer of them at the energies where they should be. “Everybody knows that from different probes, you see that there’s these vanishing electrons, but nobody knows why,” Allan said.
