In this work we perform the first comprehensive calculation of the gravitational wave spectrum of chain inflation. In contrast to slow-roll inflation the latter does not stem from quantum fluctuations of the gravitational field during inflation, but rather from the bubble collisions during the first-order phase transitions associated with vacuum tunneling. Our calculation is performed within an effective theory of chain inflation which builds on an","authors_text":"Aliki Litsa, Katherine Freese, Martin Wolfgang Winkler","cross_cats":["hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-11-06T19:00:00Z","title":"The Gravitational Wave Spectrum of Chain Inflation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2311.03434","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":"sha256:5464bf24938ef541cebd7d2295423859be8857ac2e1337eb3017ca2c48fd7d91","target":"record","created_at":"2026-07-05T07:10:31Z","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":"d4f323f8657b69ed08c5a4fde16486ce8b84bf4acd23335d7d2915600de330a3","cross_cats_sorted":["hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-11-06T19:00:00Z","title_canon_sha256":"cfbb4dbc0dd8697b56e301de29072e180a93116879bacea3b8cd74f410b400ff"},"schema_version":"1.0","source":{"id":"2311.03434","kind":"arxiv","version":1}},"canonical_sha256":"0f15a6059457e7297999c94c6659fe1176258e8206177d01daa5d94230460583","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0f15a6059457e7297999c94c6659fe1176258e8206177d01daa5d94230460583","first_computed_at":"2026-07-05T07:10:31.001455Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:10:31.001455Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"w24KM7HdelBgUWuklXNs9EZG3+JUKP+t2mNm3qSAQfjpA9t4EX5OyJ+nZ/sGUwkm4leHYWohcYhiPIe1fqCrAw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:10:31.001970Z","signed_message":"canonical_sha256_bytes"},"source_id":"2311.03434","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5464bf24938ef541cebd7d2295423859be8857ac2e1337eb3017ca2c48fd7d91","sha256:f0922100f9923942cf4d8482dc8de1603cb16a0a030fb2fffd1fa7a50c2cfaf2"],"state_sha256":"1e8bb02f9d299284e3e1a381b4061f3bf5acc86048c5e3547debffa8d6c1383f"}
