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":"b9111bae86cde02b0aff9fe1829638c463123dd1197171c3d76975f6837491d8","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 $\\mathrm{CsCr_3Sb_5}$","topic_ref":null},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"999befac942486041b6f387545310fb1f86b508db83c3de9f9f0fa142359e4e3","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"432b66189032deb1da946ebbef46555763d8f557e6c98efb75db82e14ac20bdf","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"eeoTkdPxEm7ROgZSlYDQ9aCm8my2ocj2zFo39f5QrkylkFTYcHSA9BI9RuGk4ru7bxlkjK4Xv1l1gM3PmwUBCQ"},"schema":"pubphys.envelope/1"},"record_hash":"999befac942486041b6f387545310fb1f86b508db83c3de9f9f0fa142359e4e3","leaf_index":2890}
