We then investigate the quasi-classical limit of this approach leading to a set of mutually commuting conserved operators which we refer to as the trigonometric, spin-1/2 Richardson-Gaudin system. We prove that the rational limit of the set of conserved operators for the trigonometric system is equivalent, through a change of variables, rescaling, and a basis tr","authors_text":"Inna Lukyanenko, Jon Links, Phillip Isaac","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.SI","submitted_at":"2014-05-29T03:27:33Z","title":"On the boundaries of quantum integrability for the spin-1/2 Richardson-Gaudin system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1405.7451","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c4acf7a12110cd8ec8126ddb93a79f46ad4bd8fbce53f8330bdfc26401eb76d3","target":"record","created_at":"2026-05-18T00:32:36Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"59704b14ab4290801c0da25266bd0c793fc0637c718b88a281cd675aaf824bc1","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.SI","submitted_at":"2014-05-29T03:27:33Z","title_canon_sha256":"bbce9a29466e5e215ea5878aa96b9ae4d7ee5c358a94cd8d95c3b553736a04d5"},"schema_version":"1.0","source":{"id":"1405.7451","kind":"arxiv","version":1}},"canonical_sha256":"a24a7394df6127d3955608d05655f7e750df122580304118e02c02d25b6e94b7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a24a7394df6127d3955608d05655f7e750df122580304118e02c02d25b6e94b7","first_computed_at":"2026-05-18T00:32:36.713634Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:32:36.713634Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Xc4TnAbWXPENT25ZGVfjRhjQxcBVMFqS9Pn0DGzKZL3vTZhgSPLJfy86ag0Opfqyxo5YBsflBeFq7neuv7GoCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:32:36.714264Z","signed_message":"canonical_sha256_bytes"},"source_id":"1405.7451","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c4acf7a12110cd8ec8126ddb93a79f46ad4bd8fbce53f8330bdfc26401eb76d3","sha256:8df5c9fd38a77d4818b572e020b709fef57a7d985a80bfb407764ef198f7cd1a"],"state_sha256":"54a4e823e4cd0c7618f372ee95af193202f425851d244e8b563b8c35f1c3fb5d"}
