The finding supports the idea that magnetic interactions, rather than conventional electron-phonon coupling, drive high-temperature superconductivity in cuprates, a long-standing question in condensed matter physics. Physicists say the result could help settle the mechanism debate and guide the search for higher-temperature superconductors.","why":"The Nature study addresses the unresolved mechanism behind high-temperature superconductivity in cuprates, a central question in physics.","tone":"neutral","entities":["cuprates","Nature","condensed matter physics"],"summarized_at":"2026-10-20T06:20:19.587443Z","meta":{"via":"scan","lang":"en","term":"physics","source":"Nature","published":"Mon, 19 Oct 2026 09:43:40 GMT"},"nw":null,"promo":null,"kind":null,"importance":null,"hidden":false,"hide_reason":null,"judged_at":null,"title_en":"Spin Fluctuations Linked to Superconductivity in Electron-Doped Cuprates","section_name":"Science","category_name":"Physics","timeline":[{"captured_at":"2026-10-19T12:05:37.902375Z","rank":1,"volume":null},{"captured_at":"2026-10-19T13:27:45.801400Z","rank":12,"volume":null},{"captured_at":"2026-10-19T14:49:38.774263Z","rank":10,"volume":null},{"captured_at":"2026-10-19T16:11:58.576505Z","rank":11,"volume":null},{"captured_at":"2026-10-19T17:34:42.784809Z","rank":12,"volume":null},{"captured_at":"2026-10-19T18:57:04.043818Z","rank":16,"volume":null},{"captured_at":"2026-10-19T20:19:03.265858Z","rank":14,"volume":null},{"captured_at":"2026-10-19T21:41:22.415259Z","rank":21,"volume":null},{"captured_at":"2026-10-19T23:03:21.975988Z","rank":21,"volume":null},{"captured_at":"2026-10-20T00:25:44.091261Z","rank":15,"volume":null},{"captured_at":"2026-10-20T03:09:41.162394Z","rank":14,"volume":null},{"captured_at":"2026-10-20T04:32:03.954648Z","rank":16,"volume":null},{"captured_at":"2026-10-20T05:54:25.346965Z","rank":8,"volume":null},{"captured_at":"2026-10-20T07:16:22.418092Z","rank":9,"volume":null},{"captured_at":"2026-10-20T08:38:23.577173Z","rank":17,"volume":null}],"posts":[{"platform":"news","url":"https://news.google.com/rss/articles/CBMiX0FVX3lxTFBZeDlsTUlha3NzVE44NWF2VGtGWW1PTkRCZnlUVGtwb094YU1IS0Rxb0VrVE4wNnRILXlaZS1DamJuakxlaTVETERZTzd2b1lpbk95SGlxVEZiS0FIeTJj?oc=5","author":"Nature","title":"Evidence for spin-fluctuation-mediated superconductivity in electron-doped cuprates","snippet":null,"posted_at":"2026-10-19T09:43:40Z","likes":null}],"elsewhere":[],"window":"7d"}}
