How their electrons pair, and what the superconducting state looks like in space, is still disputed.","title":"Copper-oxide superconductors: pairing and superconducting state","topic_ref":null,"why":"They hold the ambient-pressure record for superconductivity and are the reference case for every theory of pairing driven by electron repulsion."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"33286b282c1fb96cb91bff4da60a136df7a46ad812b8b7d94aa4475e741e6e76","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"9b23875d588fc831dedb20c8dacc27e3bc7b2bcf722cb21eb162171fe73c6d8a","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"oQbdJCF2u8iNWuAtCw0bH1_YN2q8G8tbKjg7sIczIsKFllljbRP-gVF5xW2_R4ZJAYHB6zsOQEYlaMuO7hn_BQ"},"schema":"pubphys.envelope/1"},"record_hash":"33286b282c1fb96cb91bff4da60a136df7a46ad812b8b7d94aa4475e741e6e76","leaf_index":122}
