However, the parametric resonance effect is very sensitive to the linearity of the reheating sector. Additional self-interactions in the reheating sector, such as non-canonical kinetic terms like the DBI Lagrangian, may enhance or frustrate the parametric resonance effect of preheating. In the case of a DBI reheating sector, preheating is described by parametric resonance of a damped relativistic harmonic oscil","authors_text":"Bret Underwood, Yunxiao Zhai","cross_cats":["astro-ph.CO","gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2013-12-11T00:30:45Z","title":"Non-Linear Resonance in Relativistic Preheating"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1312.3006","kind":"arxiv","version":3},"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":"sha256:7c5006471dc4f611f2172af6e760eec956197d9c310ecb16fa13bd78164423cc","target":"record","created_at":"2026-05-18T02:55:03Z","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":"c21172dfb43ea4689cf06459f2b052f5f3971b3f6d12e11eb29dbd4a0b93810c","cross_cats_sorted":["astro-ph.CO","gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2013-12-11T00:30:45Z","title_canon_sha256":"d9b5ddfbbe369b5a9b5547818ce82fe88756916875dba38e642e024d4c4d73e5"},"schema_version":"1.0","source":{"id":"1312.3006","kind":"arxiv","version":3}},"canonical_sha256":"8849810a028b7b2b0c2ea17b1e68249b50e3ef5de53ca352bd3d5b542e0e4076","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8849810a028b7b2b0c2ea17b1e68249b50e3ef5de53ca352bd3d5b542e0e4076","first_computed_at":"2026-05-18T02:55:03.771433Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:55:03.771433Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"f+aH8dp/UfY29/yZ0rNuVgWtkrW7jlC/fW5mxPFTNySYDnF239LQyxHbWAYZJ7V4M2pvpP1H2FA0LuckcDqPAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:55:03.772060Z","signed_message":"canonical_sha256_bytes"},"source_id":"1312.3006","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7c5006471dc4f611f2172af6e760eec956197d9c310ecb16fa13bd78164423cc","sha256:51086c09142a02d179abec40c99400368c55010a22619dee060c88eecc235dad"],"state_sha256":"f1a3cfc4d4d1fe515a117c1ba47861ccf6981f535ca3d6ada6866d2717f6e1b2"}
