The pairs appear within pair density waves, a modulated electronic state, and the discovery is likened to the Cheshire Cat's grin: superconductivity's signature lingering without the superconducting phase itself. The finding challenges assumptions about how the superconducting transition works and may reshape understanding of high-temperature superconductors.","why":"Researchers have reported a surprising observation that challenges standard theory of how superconductivity emerges and disappears.","tone":"neutral","entities":["Cooper pairs","pair density waves","superconductivity","EurekAlert"],"summarized_at":"2026-10-03T12:04:53.462435Z","meta":{"via":"scan","lang":"en","term":"physics","source":"EurekAlert!
