Scientists Expose Hidden Quantum Identity of a Superconductor

Scientists Expose Hidden Quantum Identity of a Superconductor

Two strongly coupled superconducting states can disguise themselves as a single energy gap in ultrathin materials. Two ultrathin superconductors appeared to have a simple internal structure, but closer measurements revealed something more complex. Instead of relying on one superconducting state, each material contains two strongly coupled states whose combined behavior makes them look like a [...]

Repurposing deep-Earth tools in the hunt for practical superconductors

Yale engineers use a geology press designed to simulate Earth's mantle to synthesize a promising superconducting material at lower pressures.
