Since its flatness induces the negative pressure even after inflation, the coherent oscillation of the inflaton field could fragment into quasi-stable localized objects called I-balls (or \"oscillons\"). We investigated the possibility of I-ball formation in E-models of $\\alpha$-attractors. Using linear analysis and the lattice simulations, we find that for $\\alpha\\lesssim10^{-3}$, the inflaton feels the negative pressure long enough and actually fragments into I-balls.","authors_text":"Fuminori Hasegawa, Jeong-Pyong Hong","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-10-20T11:03:58Z","title":"Inflaton fragmentation in E-models of cosmological $\\alpha$-attractors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.07487","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:ed1fe5939c32aefcc6aeba7e9a7837beb14d34534dea09787a74f98a78724fbe","target":"record","created_at":"2026-07-05T00:55:15Z","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":"d34e950e3d85613eeb3129650bf23ce83c1d15719d9f9a2ffe3bba0a2e3b7fe4","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-10-20T11:03:58Z","title_canon_sha256":"0e5d08b632628379a5ed5e0c8550cfcc806677ee444553167103b1b22f947791"},"schema_version":"1.0","source":{"id":"1710.07487","kind":"arxiv","version":2}},"canonical_sha256":"1150ddea9248b1fd60dd213d843a19ea5121522338f06224874c1351d7302326","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1150ddea9248b1fd60dd213d843a19ea5121522338f06224874c1351d7302326","first_computed_at":"2026-07-05T00:55:15.619729Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:55:15.619729Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VtMRvbJ0/iKTQbd+tAPfVelwHXEvo6WXvLYgvEYjNnKkA9H9IrlJHxcUmiigi5X3ns/KiaExEPotq2nlypxbCA==","signature_status":"signed_v1","signed_at":"2026-07-05T00:55:15.620192Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.07487","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ed1fe5939c32aefcc6aeba7e9a7837beb14d34534dea09787a74f98a78724fbe","sha256:ba49e0e159efddfddc60f5ffee276a83674cd757d6101df0e6e9c4131057eb0c"],"state_sha256":"55001b470c92815eb616fc48c958d3f5e235e1fbb3690e205f502873763b1165"}
