Scientists at JILA, working with Italian theorists, have discovered another notable similarity between ultracold atomic gases and high-temperature superconductors, suggesting there may be a relatively simple shared explanation for equivalent behaviors of the two very different systems.efficient transmission of electricity across power grids.
Described in Nature Physics,* the new research lends more support to the idea that JILA studies of superfluidity (flow with zero friction) in atomic gases may help scientists understand far more complicated high-temperature superconductors, solids with zero resistance to electrical current at relatively high temperatures. Known high-temperature superconductors only superconduct well below room temperature, but a detailed understanding of how the materials work may one day lead to practical applications such as more efficient transmission of electricity across power grids.
