This paradigm yields a hierarchy of equations between the $n$-point functions of the quantum, normal ordered, stress energy-tensor and those associated to the stochastic Einstein tensor. Assuming that the matter content is a conformally coupled massive scalar field on de Sitter spacetime, this framework has been applied to compute the power spectrum of the quantum fluctuations and to show that it is almos","authors_text":"Alberto Melati, Claudio Dappiaggi","cross_cats":["astro-ph.CO","hep-th","math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-06-09T15:44:53Z","title":"Curvature fluctuations on asymptotically de Sitter spacetimes via the semiclassical Einstein's equations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.2223","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:a16d9fef6c1c642c64809c7886b31b39f2e9f61502eb6af477145e5eb0fd92ed","target":"record","created_at":"2026-05-18T01:43:01Z","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":"5b766b68747b0da407dc58a1fade67319ba559c41a832f22fe914dc1bebf5fc2","cross_cats_sorted":["astro-ph.CO","hep-th","math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-06-09T15:44:53Z","title_canon_sha256":"7638406866e2cb7e05ce3d2c1bea6cce8725276131dff11eb5b70772d301d441"},"schema_version":"1.0","source":{"id":"1406.2223","kind":"arxiv","version":1}},"canonical_sha256":"7a90fff432ea08d69c3fc70803e774bd5b2c25494a2ff3fffc2079a3c37a60f7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7a90fff432ea08d69c3fc70803e774bd5b2c25494a2ff3fffc2079a3c37a60f7","first_computed_at":"2026-05-18T01:43:01.056388Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:43:01.056388Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"V2PoyixU+NmTz4v6R5evQS4ILaaBhV+NnCWCRHDJohRYoR68rYTaoCpS7n/EKTQ12sa5xKYkRpDGsbm4O1QJCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:43:01.056823Z","signed_message":"canonical_sha256_bytes"},"source_id":"1406.2223","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a16d9fef6c1c642c64809c7886b31b39f2e9f61502eb6af477145e5eb0fd92ed","sha256:74afa39d4be3e7b5caf9db861b9bda8217071df2dd5d669e0ad0bb7f29646990"],"state_sha256":"58c30e5f1be82b417b833a1cdd9c88e11492bb845b1548396e7601657793f8bb"}
