Our goal is to prove the match between the bulk Iyer-Wald entropy and the field theory entropy for various symmetry algebras (CFT$_2$, Warped CFT$_2$, BMS$_3$). We also discuss phase transitions in higher curvature theories, and argue that, in the flat case, there is strictly speaking no phase transition in the grand canonical ensemble.","authors_text":"C\\'eline Zwikel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-04-07T19:15:18Z","title":"BTZ Black Holes and Flat Space Cosmologies in Higher Derivative Theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.02120","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:e51693f34fbd95b421a78d600b9e75204409e4068f4fdea5becda6e31057cf79","target":"record","created_at":"2026-05-18T00:29:21Z","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":"61c545abf52cfd79112d54253924976022cc842984d7291fcb5f39aa25590ee6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2016-04-07T19:15:18Z","title_canon_sha256":"620b77e6c29114efe86da745aa7a551883339c8e24457be2c8d4ec2feaf1089c"},"schema_version":"1.0","source":{"id":"1604.02120","kind":"arxiv","version":3}},"canonical_sha256":"26da1100a35b2fa6a78e4dc1fa3722b95cafcac1827c0f7fcdfc807c9dbbb240","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"26da1100a35b2fa6a78e4dc1fa3722b95cafcac1827c0f7fcdfc807c9dbbb240","first_computed_at":"2026-05-18T00:29:21.290822Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:29:21.290822Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kywJsriWqqh0hpgQkS7KN4Olrpg3rS4DIegvAwSinhB3U0yCwjuGvctKdabBMw6+b7LnZQ9lryFl+4T/X6QPAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:29:21.291407Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.02120","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e51693f34fbd95b421a78d600b9e75204409e4068f4fdea5becda6e31057cf79","sha256:b24fc79ead945ca27ce721568ad2b5b26e5810fa2c23ca512e5ceb65109d7e52"],"state_sha256":"bf0ce8baef4ce1bfc14594d5e1f66517f2ad970e4cf5b59da51635780b406e67"}
