The calculation involves first the generation of the Gaussian state and subsequent measurements of two photons a time $\\tau \\geq 0$ apart. The generation of the Gaussian state by the parametric amplifier insures that the temporal second-order coherence function depends only on $\\tau$.","authors_text":"Moorad Alexanian","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2015-01-08T15:52:13Z","title":"Exact temporal second-order coherence function for displaced-squeezed thermal states"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.01887","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":"sha256:6caa474c8c68e52f622f4b672f313c09df005d93ff128b0b39c8050bb15798af","target":"record","created_at":"2026-05-18T02:29:46Z","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":"eaf82079719f16962d1b13c86c602bef99571bb72daf920b7c333493e9e4c9cd","cross_cats_sorted":["cond-mat.stat-mech"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2015-01-08T15:52:13Z","title_canon_sha256":"58ca25f8746536cf5265377a6ffc5e3970888620a6fe81fd923c694e107bfa63"},"schema_version":"1.0","source":{"id":"1501.01887","kind":"arxiv","version":1}},"canonical_sha256":"96da7911ae1502e9b62eb67ac558bafdd22991a49c1108d80defd063dcc0ae0c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"96da7911ae1502e9b62eb67ac558bafdd22991a49c1108d80defd063dcc0ae0c","first_computed_at":"2026-05-18T02:29:46.146648Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:29:46.146648Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gPoJZaDn++SFb80RRgyRDazOp6cnmz0xYp3UDWcCgl//FHZTZXmHLIS27733NdL0sTk59+hLe8lSplb20Hn6Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:29:46.147204Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.01887","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6caa474c8c68e52f622f4b672f313c09df005d93ff128b0b39c8050bb15798af","sha256:2678d2691cf870a25fbb026d682d3c554d839e916d17718fe655f3475b81a03f"],"state_sha256":"8073572fd35e82b27c149a952e6d13c4e2aa31b824aee201f6df4b64f90a0750"}
