We extend previous work to include random initial conditions for the scalar fields, and explore the predictions for density perturbations and the tensor-to-scalar ratio. The tensor-to-scalar ratio depends only on the number of e-foldings and is independent of the number of fields, their masses, and their initial con","authors_text":"Andrew R Liddle, Soo A Kim","cross_cats":["hep-th"],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2006-05-24T11:42:04Z","title":"Nflation: multi-field inflationary dynamics and perturbations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0605604","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":"sha256:17f0173f5aae3e5bb283d4584976a65001a32691286125ceaa7a0b950fcdd651","target":"record","created_at":"2026-07-04T16:58:47Z","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":"32c903ee09025efcd7c3e73b94fd7321db01024283086c48865c721e93dc0a35","cross_cats_sorted":["hep-th"],"license":"","primary_cat":"astro-ph","submitted_at":"2006-05-24T11:42:04Z","title_canon_sha256":"4dddce5b1f9e2a3e0e30f3256bec8303dbe821a25d04431491157cc73d86f094"},"schema_version":"1.0","source":{"id":"astro-ph/0605604","kind":"arxiv","version":2}},"canonical_sha256":"e12d60e5ebe71d61e23895af140e4b9eec70ec0026b143fd1ad006ad57b4a9b3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e12d60e5ebe71d61e23895af140e4b9eec70ec0026b143fd1ad006ad57b4a9b3","first_computed_at":"2026-07-04T16:58:47.213056Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:58:47.213056Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"exNfW0dTOW0ztU2kBC/8la1jHR8NaEGncNJiOQx3AXSwWEYk9oJv68sLLPFvhdyJ2wfCaofuEx65i5BOUnnXAA==","signature_status":"signed_v1","signed_at":"2026-07-04T16:58:47.213402Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0605604","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:17f0173f5aae3e5bb283d4584976a65001a32691286125ceaa7a0b950fcdd651","sha256:c280cbf99fa233c42cfaf1cdafaad2b8795560fdac8c35b1b7661d26d71bcb29"],"state_sha256":"dfed8e8b101eb599c5dc183758c6173a25588b2797356e22bff1ef8d1d33633a"}
