Cuprate-superconductor (IMAGE) Max-Planck-Gesellschaft Caption A look inside a high-temperature superconductor: The Max Planck scientists in Stuttgart used resonant X-ray scattering to show the existence of charge-density waves inside the cuprate superconductors. The blue wavy lines indicate the incident and emitted radiation. The system of coordinates illustrates the orientation of radiation relative to the crystal axes a, b and c.
