Identify the density-wave order (wavevector, moment arrangement, altermagnetic or not) and determine whether its quantum critical fluctuations drive pairing. An answer is a refined magnetic structure and pressure phase diagram from neutron scattering, muSR or NMR under pressure, plus a gap-symmetry measurement in the superconducting phase.","problem_ref":null,"references":"","settled_by":"Magnetic structure determination at ambient pressure followed under pressure to the superconducting dome, with gap structure from penetration depth or NMR under pressure.","status_note":"An altermagnetic ground state of the distorted structure was proposed in 2025 (Nature Communications); the order under pressure near the superconducting dome is unmeasured.","title":"Density-wave order and pairing in pressurized CsCr3Sb5","topic_ref":"b07aceae6ac0e1690fea48db269288e8ac55a50f722f8f0e6cf26c1685ae1e5a"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"b9111bae86cde02b0aff9fe1829638c463123dd1197171c3d76975f6837491d8","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"4101ced4f45dcbbe60e65288c911d0d0d8c013c0f988b84bdce1395bf8bbfc92","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"Dx9sDKw1-07mcSOo7bqRXGMtc3es8qEPJTGFrxaZhdEhfBnx0jdgwasLbRRBIF05XDIdlC8BaxyRas5BjeQsAQ"},"schema":"pubphys.envelope/1"},"record_hash":"b9111bae86cde02b0aff9fe1829638c463123dd1197171c3d76975f6837491d8","leaf_index":1051}
