Abstract
The mystery of how electrons in a high-temperature superconductor flow without resistance grows deeper. New pictures at the atomic scale reveal two electronic phases that — like oil and vinegar — do not easily mix.
According to quantum mechanics, when space is the same everywhere, a particle should be everywhere at the same time. In low-temperature metals and superconductors, this principle rules the waves of the quantum fluids formed by the electrons.
