MunichElectron pairs show up at the pseudogap’s energy.
It points to pairs forming before superconductivity does, in materials that work with cheap liquid nitrogen.
Milan Allan’s team used a scanning tunneling microscope to hear shot noise, which rises when charges arrive in pairs.
The team could not listen above the superconducting temperature, where the pseudogap is usually defined.
Ingmar Swart of Utrecht University wants higher-resolution noise maps and an instrument that detects coherence directly.
How each outlet framed it
- Ars Technica
- frames the pseudogap as a phenomenon of missing electrons, tying the Munich-Utrecht noise measurements to the vanishing-electron debate
