Determine whether nematic fluctuations contribute measurably to pairing given that coupling to lattice strain cuts off the divergence of the nematic correlation length. An answer is a quantitative estimate of the nematic contribution to the pairing interaction with an experimental test, such as $T_{c}$ versus nematic susceptibility under tuned strain.","problem_ref":null,"references":"","settled_by":"Strain-tuned measurements of $T_{c}$ and nematic susceptibility in a single system with magnetic and nematic critical points separated, compared with a model calculation.","status_note":"","title":"Do nematic quantum critical fluctuations enhance $T_c$","topic_ref":"71fc7a5f7f45e0e897c1da37458bfa12479b8a0797fe32805a586a3c8fc44007"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"3ead336b9bdac11bd4f727aef256eb7a0334c3b6a1c52677bd4f3b0a080d1d01","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"114f0a603288c1c1ded1c61744bf62320bcaaf869f270974a286b6bf8856e9c8","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"_ClP43RsIq3Xxa4MDlikhHTttYvLVrDvJGdWXPMtHZMm5Jrw4havg5sLToaX-fbM-5DDvaM-8xTHFwnQb04fDg"},"schema":"pubphys.envelope/1"},"record_hash":"3ead336b9bdac11bd4f727aef256eb7a0334c3b6a1c52677bd4f3b0a080d1d01","leaf_index":1047}
