High-temperature superconductivity

Charting the pseudogap

Hole-doped cuprate superconductors exhibit an enigmatic state known as the pseudogap state. Mapping the distribution of this state as it evolves in real space with doping indicates that the moment the pseudogap fills the material is when superconductivity emerges — suggesting an intimate connection between the two.
