Ghostly Cooper Pairs Found Above Superconductivity Limit in Uranium Ditelluride
Original: Ghostly Cooper Pairs Persist Above Superconductivity’s Critical Temperature in Uranium Ditelluride
Researchers report that Cooper pairs in uranium ditelluride persist above the material's superconducting critical temperature, a phenomenon described as ghostly because the pairs exist without producing zero electrical resistance. The finding suggests superconducting correlations survive into the normal state in this unusual heavy-fermion superconductor, offering new clues about unconventional superconductivity and possibly topological behaviour in uranium ditelluride.
Why now: The surprising survival of Cooper pairs above the critical temperature challenges standard pictures of superconductivity.
