The capacity is labeled by the replica parameter which plays a similar role to the inverse temperature in thermodynamics. In the end of the world brane model of a radiating black hole the capacity has a peak around the Page time indicating the phase transition between replica wormhole geometries of different types of topology. Similarly, in a moving mirror model describing Hawking radiation the capacity typically shows a discontinuity when the dominant saddle switches between two phases, which ","authors_text":"Kento Watanabe, Kohki Kawabata, Tatsuma Nishioka, Yoshitaka Okuyama","cross_cats":["gr-qc","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2021-02-04T05:55:05Z","title":"Probing Hawking radiation through capacity of entanglement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2102.02425","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":"sha256:146355ebd151b48b3c13ebeb4fc545302e021ad63710312f467ff2bea61f295e","target":"record","created_at":"2026-07-05T02:44:54Z","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":"bfdf1e1539dc201be8875d6ccc92275a2cee281c2c0de19861649ecd036cd360","cross_cats_sorted":["gr-qc","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2021-02-04T05:55:05Z","title_canon_sha256":"4c174f76f1a1ed29610d9df5c2dc79e646da23f187059e24e78ae0b473e88450"},"schema_version":"1.0","source":{"id":"2102.02425","kind":"arxiv","version":3}},"canonical_sha256":"ccf39554d341a4a9b0849c147d08cff2529972c6d36bc550b2827abcb18356e0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ccf39554d341a4a9b0849c147d08cff2529972c6d36bc550b2827abcb18356e0","first_computed_at":"2026-07-05T02:44:54.470551Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:44:54.470551Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zSQF8RqHUIiNSJpuYrY6q9bs9E3MNJWpqCnjB5sVLMYdySk1O600Qp6L2h9JawLcPd6X4DMXTUDLrfIPNWk+CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:44:54.470992Z","signed_message":"canonical_sha256_bytes"},"source_id":"2102.02425","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:146355ebd151b48b3c13ebeb4fc545302e021ad63710312f467ff2bea61f295e","sha256:6ef3dcbd3fc3da7f6d902bd8e241d21f384f23bbc6ea4193e50b941e45b516fd"],"state_sha256":"1121dabb4ea210d7f1c140c5a62feccc5aa60594ac75fbff6cd48f320bbda695"}
