By employing the algebraic Bethe ansatz, we determine the exact solution for the energy spectrum. An asymptotic analysis is conducted to determine the leading terms in the ground state energy, the gap and some one point correlation functions at zero temperature.","authors_text":"Angela Foerster, Huan-Qiang Zhou, Jon Links, Xi-Wen Guan","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"","primary_cat":"cond-mat.str-el","submitted_at":"2002-05-07T17:44:40Z","title":"Integrability and exact solution for coupled BCS systems associated with the $su(4)$ Lie algebra"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/0205124","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":"sha256:4da2abb2852bc4804cf31b22d6e0766bf2168e95fe4de425fae7ddbce245fbf9","target":"record","created_at":"2026-05-18T01:40:03Z","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":"6326e596fc7477309bb5d48ea2a7e00a74632dab62ed18909357b3c69aa8562f","cross_cats_sorted":["cond-mat.stat-mech"],"license":"","primary_cat":"cond-mat.str-el","submitted_at":"2002-05-07T17:44:40Z","title_canon_sha256":"190153b233df1dbd1a79e36ee3fa6b01e8849b270e658aef05a626aa952e7340"},"schema_version":"1.0","source":{"id":"cond-mat/0205124","kind":"arxiv","version":1}},"canonical_sha256":"0137a03451001987573861151f400b7189d3daf43d1db8894c747bc2c4e4e912","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0137a03451001987573861151f400b7189d3daf43d1db8894c747bc2c4e4e912","first_computed_at":"2026-05-18T01:40:03.561249Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:40:03.561249Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pDbUgqgFvOyGXEYoFDs2X5kOmUDMYAmnzeBn6/q4YN1R4++OLPAjrDXhxdB8hxE6avkCK1ZWxKoqK9rs/6avBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:40:03.562038Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/0205124","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4da2abb2852bc4804cf31b22d6e0766bf2168e95fe4de425fae7ddbce245fbf9","sha256:de4e1eb501b891f2c8c8bd4bdb35647143c09139e9040ad48f45279a6dccac43"],"state_sha256":"e65717b31cc1f250557f30d05579a7c0a1e451cece24fef122f0f3418a98efc1"}
