Dancing with high-temp superconductors
A computer-generated representation of the data obtained by scanning a cuprate superconductor in sub-atomic steps. Each cross represents a “Cooper pair” of electrons. At a temperature below 37K (bottom sheet) the pairs are in an orderly arrangement and current can flow without resistance. At a higher temperature the Cooper pairs are still present, but no longer orderly. (Credit: Jhinhwan Lee/Davis Group/Cornell University)
