The Boulware, Hartle-Hawking and SL(2,R) invariant vacua are constructed, together with their Green functions and stress tensors, for both massive and massless scalars in an AdS_2 black hole. The classical Bekenstein-Hawking entropy is found to be independent of the temperature, but at one loop a non-zero entanglement entropy arises. This represents a logarithmic violation of finite-temperature decoupling for AdS_2 black holes which arise in the near-horizon limit of an asymptotically flat black hole.","authors_text":"Andrew Strominger, Marcus Spradlin","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1999-04-21T19:41:24Z","title":"Vacuum States for AdS_2 Black Holes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9904143","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:f00bcbb8e01e576d4542b1e300654d7e23eaff8847108ad27b74a7b3c05e9c95","target":"record","created_at":"2026-07-04T16:14:49Z","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":"527ff5a142fc0923d2567c93706f0778f5481e2fd179a65a0d63a6ce91e1961f","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1999-04-21T19:41:24Z","title_canon_sha256":"0cec7b992a3ebf0aefcee3e601b01576424c1da555e6f5400d05bfda597d55ee"},"schema_version":"1.0","source":{"id":"hep-th/9904143","kind":"arxiv","version":2}},"canonical_sha256":"11dc2f52efe1f8adcaf11780f466de3bd547005e087f6c33b7c76e278a0d7c42","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"11dc2f52efe1f8adcaf11780f466de3bd547005e087f6c33b7c76e278a0d7c42","first_computed_at":"2026-07-04T16:14:49.336982Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:14:49.336982Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"A+1SOIaoo5tIp8c6V13Tr8hUY4vdxOw8fziOdugcOcEcPQQT/4KGmpDWtjuQQolERhtbnCAxaKIFKOZ/zdZ0BA==","signature_status":"signed_v1","signed_at":"2026-07-04T16:14:49.337389Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9904143","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f00bcbb8e01e576d4542b1e300654d7e23eaff8847108ad27b74a7b3c05e9c95","sha256:28b4ec59a3d704d33f3fc747a2141e88af63e366ffae04f9f8303f681a619ed8"],"state_sha256":"9974addb8784df9d526ea96dc0a2952f0a26cf33ecd458c29785b35c303c0e5f"}
