A key result in unitary quantum field theories is the Bisognano-Wichmann theorem, which establishes the locality of the entanglement Hamiltonian. In this work, our focus is on the non-Hermitian Su-Schrieffer-Heeger (SSH) chain. We study the entanglement Hamiltonian both in a gapped phase and at criticality. In the gapped phase we find that the lattice entanglement Hamiltonian is compatible with a lattice Bisognano-Wichmann result, with an entanglement temperature linear in the","authors_text":"Federico Rottoli, Michele Fossati, Pasquale Calabrese","cross_cats":["cond-mat.stat-mech","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-02-07T11:55:53Z","title":"Entanglement Hamiltonian in the non-Hermitian SSH model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.04776","kind":"arxiv","version":1},"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:f24e9d70c0a36fe6fb8b228fcd64734d028d9b05c72339562f8a56215ddfce17","target":"record","created_at":"2026-07-05T07:42:32Z","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":"364d8b381727060a61f34821eb50fe668534a682b998c46d4ea42b0be7198db2","cross_cats_sorted":["cond-mat.stat-mech","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-02-07T11:55:53Z","title_canon_sha256":"683a22f7f4d30c94ca5f4c495c6cbdacb8581c774a39a0a09ee018f289b5b394"},"schema_version":"1.0","source":{"id":"2402.04776","kind":"arxiv","version":1}},"canonical_sha256":"ef2474aa726b33d64441eedf9448fe574cdc0364b1cc23576dab146a4edb0b47","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ef2474aa726b33d64441eedf9448fe574cdc0364b1cc23576dab146a4edb0b47","first_computed_at":"2026-07-05T07:42:32.351042Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:42:32.351042Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"q9VwcN/wGTtn7//4g6OxR1AxySeCf3rI5RQvGjEfNKj0RHU3H4EwZ7y99LPIwyY2/QQ+Z0ao5QoeXXuDOlv8CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T07:42:32.351519Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.04776","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f24e9d70c0a36fe6fb8b228fcd64734d028d9b05c72339562f8a56215ddfce17","sha256:de277c120f0db8182e444796ac6d2be64e7572c80637987f7e7deec1d6894381"],"state_sha256":"2f6b04318c007b835e66ab3fb34f381c8855ac4fda3e3ca9f328c332070ca08d"}
