The rich interplay of disorder, non-Hermiticity, and topology is epitomized by the recently proposed non-Hermitian topological Anderson insulator that hosts a plethora of exotic phenomena. Here we experimentally simulate the non-Hermitian topological Anderson insulator using disordered photonic quantum walks, and characterize its localization and topological properties. In particular, we focus on the competition between Anderson l","authors_text":"Kunkun Wang, Lei Xiao, Peng Xue, Quan Lin, Tianyu Li, Wei Yi","cross_cats":["cond-mat.dis-nn","cond-mat.quant-gas","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2021-08-02T18:00:18Z","title":"Observation of non-Hermitian topological Anderson insulator in quantum dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2108.01097","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:baf135275357490cdf40fea19899e19e90abe31c35738c66284690785fb3e37c","target":"record","created_at":"2026-07-05T04:31:22Z","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":"83827c2dc25c04ca93c3f86f0689c4d108d0cb93cf3438371d765a9e85affc68","cross_cats_sorted":["cond-mat.dis-nn","cond-mat.quant-gas","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2021-08-02T18:00:18Z","title_canon_sha256":"837774728aaee706b90297b685a58ade91328dd1958f1310daaa5958b996cd2e"},"schema_version":"1.0","source":{"id":"2108.01097","kind":"arxiv","version":1}},"canonical_sha256":"d74d236586373099db0e6b087c9b45b8a1946824db110cc30331f842d54934ea","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d74d236586373099db0e6b087c9b45b8a1946824db110cc30331f842d54934ea","first_computed_at":"2026-07-05T04:31:22.937479Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:31:22.937479Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"s3XIW9cnJ7G242KGHIrnbUIefZwf4GvWtxe2bl7LYvEuOWCLNASYYiy+SnWvUUtU2dvwaHoUi0kFXjGTnCCMCg==","signature_status":"signed_v1","signed_at":"2026-07-05T04:31:22.937964Z","signed_message":"canonical_sha256_bytes"},"source_id":"2108.01097","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:baf135275357490cdf40fea19899e19e90abe31c35738c66284690785fb3e37c","sha256:dcb162eb3c26fb6c88bcc50bdd93558e417ba093155b1b08afa358102bc091f8"],"state_sha256":"fba7aaba2746198d8a225390b7a8216c6349e9fbc6e2f31f117abf6daa9efbe4"}
