Molecules are first pumped into an excited triplet state, and the triplet-singlet conversion is facilitated by a two-step spontaneous decay through the coupled $A^{1}\\Sigma_{u}^{+} \\sim b ^{3}\\Pi_{u}$ states. Using spectroscopic data and accurate quantum chemistry calculations for Cs$_2$ potential curves and transition dipole moments, we show that this process has a high rate and competes favorably with the single-photon d","authors_text":"Marin Pichler, Mireille Aymar (LAC), Nadia Bouloufa (LAC), Olivier Dulieu (LAC)","cross_cats":["physics.atom-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-11T05:50:13Z","title":"Triplet-singlet conversion in ultracold Cs$_2$ and production of ground state molecules"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.2563","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":"sha256:2391bacaf0339db898bd0793ac159056b1dc2b3065c27eea18ea8e55063bfab8","target":"record","created_at":"2026-05-18T02:04:49Z","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":"f51c82ffbdfbeeafb99c98675d1d923dc09ab4c0db84dedbb258698f7cfc5ea4","cross_cats_sorted":["physics.atom-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-11T05:50:13Z","title_canon_sha256":"6d1a8a4756b742d30badfc0ef8c66514e41863c0d0aa12480883b28c05b204f0"},"schema_version":"1.0","source":{"id":"1011.2563","kind":"arxiv","version":1}},"canonical_sha256":"d15bc1e10f44965e2eb30620cd4fd8840c8b801af436ccca4e2efbc1cc2f50b7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d15bc1e10f44965e2eb30620cd4fd8840c8b801af436ccca4e2efbc1cc2f50b7","first_computed_at":"2026-05-18T02:04:49.035889Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:04:49.035889Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Kyta0cAaGj3Xszeqmz6Drvx/RD65Cbti9dR0SF2AZwEEFBJgzYl5ehPHuIM5KGgGninOS+r2h8nvSmnbPfM9Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:04:49.036609Z","signed_message":"canonical_sha256_bytes"},"source_id":"1011.2563","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2391bacaf0339db898bd0793ac159056b1dc2b3065c27eea18ea8e55063bfab8","sha256:2732f8603151e278a41675c90f0ce3b1dba2c9aaa916a8d8f68b301754aa8ecd"],"state_sha256":"b62e011ae218e2424e3cba2f22916a825b9bc24918235cb21b32ffb4ab38e855"}
