Whether these effects mark a new phase of matter, and what reorganizes the Fermi surface (the boundary between occupied and empty electron momenta), is not settled.","title":"Cuprate pseudogap, charge order and Fermi-surface reconstruction","topic_ref":null,"why":"The pseudogap region is where cuprate theories disagree most, and its endpoint lies near the strange metal and the doping of highest $T_{c}$."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"0b1624cb419c381bddad004c2bf5315f0b67a5717967d1ceb30488890c34b90a","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"bc82f4f94eae98a848d9b0d3c98051d06f159933b49f641c5b71841c6907ff45","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"BwtVkwxDAG9-09oFUwIqqhMdJZGHi4jWBexPeTWhXpV4FDq_6FEDMM_3FAj7ssr3MTPoegUwho5WPSDEde8qBw"},"schema":"pubphys.envelope/1"},"record_hash":"0b1624cb419c381bddad004c2bf5315f0b67a5717967d1ceb30488890c34b90a","leaf_index":121}
