Cooper pairs found above superconducting critical temperature
Original: Cooper pairs found above superconducting critical temperature in pair density waves
Researchers report that Cooper pairs — pairs of electrons responsible for superconductivity — can persist above a superconductor's critical temperature within pair density waves. The finding suggests pairing survives in some form even when the material no longer conducts electricity without resistance. Physicists say the observation could reshape understanding of how superconductivity emerges, particularly in unconventional superconductors.
Why now: The result challenges the standard view that superconducting pairs exist only below the critical temperature, a significant development in condensed-matter physics.
