Four-wave mixing in this situation produces atom pairs in two well defined beams. We show that these beams present a narrow momentum correlation, that their momenta are precisely tunable, and that this pair source can be operated both in the regime of low mode occupancy and of high mode occupancy.","authors_text":"Alain Aspect (LCF), Christoph I Westbrook (LCF), Denis Boiron (LCF), Jean-Christophe Jaskula (LCF), Josselin Ruaudel (LCF), Marie Bonneau (LCF), Rapha\\\"el Lopes (LCF)","cross_cats":["physics.atom-ph","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2012-12-27T07:06:05Z","title":"Tunable source of correlated atom beams"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.6315","kind":"arxiv","version":2},"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:ace869554c012df34389f7680e9286a18339ff61cf4d9c32ec6167e2424f3abf","target":"record","created_at":"2026-05-18T03:19:45Z","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":"50826f4beddedbc907a18a65d67fa2d2d3ae0df9c9fde817a75ba3625c0ce3ea","cross_cats_sorted":["physics.atom-ph","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2012-12-27T07:06:05Z","title_canon_sha256":"3b93488e4c7537bae73037c62e5d132bdde737712e288b9f64d037c6850cfa90"},"schema_version":"1.0","source":{"id":"1212.6315","kind":"arxiv","version":2}},"canonical_sha256":"67f3309d6ea7c2ca484da7f693cc8877427c37b0d2b5421d029a1e1c36beaaf4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"67f3309d6ea7c2ca484da7f693cc8877427c37b0d2b5421d029a1e1c36beaaf4","first_computed_at":"2026-05-18T03:19:45.832082Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:19:45.832082Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b9/7hRaEVvc6wY41idtWzauceERfduW/BetjyWMxKUq7RkL2OOqbkBe2zuo7J5afqunwDM/RPoxXMlRwswnhCA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:19:45.832747Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.6315","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ace869554c012df34389f7680e9286a18339ff61cf4d9c32ec6167e2424f3abf","sha256:ad94214ab20a78ac42b5aa70ba4a40d389f23215eb550b66bcedc8b53df7570c"],"state_sha256":"e326b045f68013bb28dbba5d1a2584dd7506b23e8880417c4331492cd0aa70a5"}
