Cooper pairs found persisting above superconducting critical temperature
Original: The Cheshire Cat’s grin: Cooper pairs found above superconducting critical temperature in pair density waves
Researchers report detecting Cooper pairs in pair density waves above the superconducting critical temperature, a phenomenon likened to the Cheshire Cat's grin: superconducting order persisting even where superconductivity itself has vanished. The finding, announced via a research press release, could reshape understanding of the superconducting transition and the nature of high-temperature superconductors.
Why now: A new experimental observation challenging the textbook view that superconducting Cooper pairs cannot exist above the critical temperature.
