The baby universe spacetime originates from the black hole interior in Jackiw-Teitelboim (JT) gravity. The holographic description is a low-temperature thermal pure state of two Sachdev-Ye-Kitaev (SYK) models. The construction of the state relies on the insertion of a heavy matter operator, which supports the baby universe, together with a first-order thermal phase transition between a black hole phase and an empty Anti de Sitter (AdS) phase. For the transition, we employ a version of the Maldacena-Qi phase tr","authors_text":"Alejandro Vilar L\\'opez, Brian Swingle, Martin Sasieta","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2025-11-28T19:00:00Z","title":"Baby Universes from Thermal Pure States in SYK"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2512.00149","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:afbf9ca204fd86252663e3797fc08275806af127769b3af2f21ce57f086184d1","target":"record","created_at":"2026-06-12T01:08:18Z","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":"92ea5631c60bf5ae45d7192ef6bd608f909be5236e58ab7b3efdd988829d219a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2025-11-28T19:00:00Z","title_canon_sha256":"7336dda392a5a50265cfae1b535d9705cace7491253e788f57330bc02c94d100"},"schema_version":"1.0","source":{"id":"2512.00149","kind":"arxiv","version":2}},"canonical_sha256":"5fe579bcaa4c0cd7f89be6bb64aa48994c3940341df5df2c07427c0b8c9d1b49","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5fe579bcaa4c0cd7f89be6bb64aa48994c3940341df5df2c07427c0b8c9d1b49","first_computed_at":"2026-06-12T01:08:18.718416Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-12T01:08:18.718416Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"abJcCugdB7XxeRy01RgE/HyF0Efh6Fg/pUITCCNSTWXSGdISxlms436FWVhvkZhWtWU0Ld8m6AK25aiiqJrvAg==","signature_status":"signed_v1","signed_at":"2026-06-12T01:08:18.719558Z","signed_message":"canonical_sha256_bytes"},"source_id":"2512.00149","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:afbf9ca204fd86252663e3797fc08275806af127769b3af2f21ce57f086184d1","sha256:1d17ed0db05120c5fa733fe7b9416129447da981e84e908a01ed105104f9ea3b"],"state_sha256":"cb132d12bb77c5701245fc803eb232a7166d430c3ffd0cea8fe8a717b72a56ef"}
