The resulting entanglement entropy is found to be proportional to the entangling surface as expected. A logarithmic subleading term with positive coefficient is also found through numerical computation. We have extended the analysis to higher dimensions as well.","authors_text":"Suman Ghosh","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-05-26T05:13:27Z","title":"Entanglement entropy due to near horizon degrees of freedom"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1405.6461","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:cffacec437aad2aca0d0258f40025b037bb60bb821bdbe6fff42d4df504934b2","target":"record","created_at":"2026-05-18T01:35:12Z","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":"b6013e971f09c3e60908f0a2e5f317e8a2b990c2bf6f01505fe51a131d536e33","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-05-26T05:13:27Z","title_canon_sha256":"254a1f8b7f16c53d35295a174eee5b025badfdb0c035abe8bace179540cfd9f9"},"schema_version":"1.0","source":{"id":"1405.6461","kind":"arxiv","version":2}},"canonical_sha256":"657db418b449181581e5d4e0018f679d851120f7168fd39968d767ec45ccf446","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"657db418b449181581e5d4e0018f679d851120f7168fd39968d767ec45ccf446","first_computed_at":"2026-05-18T01:35:12.275153Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:35:12.275153Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"H0FUaQGylrkGqOiv9/XUXGQDactbN4/mtYcrlMzgz4DKjR12yDu/l/3LIzHaKYWIrCLjCcrIIqFqfTXzz7v8Aw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:35:12.275738Z","signed_message":"canonical_sha256_bytes"},"source_id":"1405.6461","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cffacec437aad2aca0d0258f40025b037bb60bb821bdbe6fff42d4df504934b2","sha256:9dcbefeac688799ce1dd3ce271df6f86ca53ae2a90a78bfeab8cd9d556958cbd"],"state_sha256":"69a5ce208dc8970560fe908e0ef48817a80ea235811f79c67ca80c0a83d5fcc7"}
