As a concrete example, we study a two-field inflationary model where the initial spectator field is non-minimally coupled to gravity while the initial inflaton field is minimally coupled. The non-minimal coupling results in the growth of the spectator field which, in turn, drives the second stage of inflation in a significant region of parameter space. The isocurvature fluctuations originating from the spectator field source adiabatic ones, and hence the spectator non-minimal coupling can modif","authors_text":"Kin-ya Oda, Mio Kubota, Stanislav Rusak, Tomo Takahashi","cross_cats":["gr-qc","hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2022-02-10T06:59:09Z","title":"Double inflation via non-minimally coupled spectator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2202.04869","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":"sha256:29a3c126451b25fba80df404d5b22888a315f00a371b17f7cc62b663893b2d01","target":"record","created_at":"2026-07-05T04:33:30Z","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":"eab2987bd9817ef1c6b3a6431b826107a02dc9cc5862309f596138e8141809eb","cross_cats_sorted":["gr-qc","hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2022-02-10T06:59:09Z","title_canon_sha256":"54cf5d81f6c7116cecc0034ad41c892cfc182cc34c9b55e36c356ddf5af812f8"},"schema_version":"1.0","source":{"id":"2202.04869","kind":"arxiv","version":1}},"canonical_sha256":"183cc698a65de5956e8eabfb9e42c212d0da4a91eb31767867c26ef345493f01","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"183cc698a65de5956e8eabfb9e42c212d0da4a91eb31767867c26ef345493f01","first_computed_at":"2026-07-05T04:33:30.402791Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:33:30.402791Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"c98IEpuvbRdj6ORraO590PJkztqRLE2ST7vbfE6gq4pktHb0BTpWkF450u4INC5PQ/EOpgS6QrHtAWr2dsp2Ag==","signature_status":"signed_v1","signed_at":"2026-07-05T04:33:30.403278Z","signed_message":"canonical_sha256_bytes"},"source_id":"2202.04869","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:29a3c126451b25fba80df404d5b22888a315f00a371b17f7cc62b663893b2d01","sha256:2314ff879a07e78eae622436597bd66a711d876671bd1aca6d667252e9b22efb"],"state_sha256":"2d1be108f6aa26220ad18b0bcbf5d516bfc31dfc01959634d5c678ad99bff80a"}
