A key problem in this direction is the interplay between the effective gauge potential and the non-Hermiticity. Here we tackle this problem in a synthetic non-Hermitian Hall ladder and experimentally observe antichiral edge currents (ACECs) of photons, by tuning the locally uniform effective magnetic flux and the on-site gain/loss. Such ACECs provide a topological method to probe the signatures of the non-Hermitian skin effect (NHSE) from steady-state bulk dynami","authors_text":"Da-Wei Wang, Guangzhen Li, Liang Jin, Luojia Wang, Luqi Yuan, Rui Ye, Xianfeng Chen, Xiaoxiong Wu, Xin Qiao, Yanyan He, Yuanlin Zheng","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2023-05-29T02:35:31Z","title":"Observation of non-Hermitian antichiral edge currents"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2305.17853","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":"sha256:6773b8574867729f9458f07fd02b57469ea18ae93bda1655a23a6acd3432a97f","target":"record","created_at":"2026-07-05T09:58:16Z","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":"1fe14981c82064b2af87ebf0e3c8df8d33e794ee692cb400860e0984cd530bd2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2023-05-29T02:35:31Z","title_canon_sha256":"482a4cf5a434ec098a9a3713ed083688b983c98fdaecd0e7635b0988530d2098"},"schema_version":"1.0","source":{"id":"2305.17853","kind":"arxiv","version":1}},"canonical_sha256":"603fc584e9657c2dc92f6beb261e9ef09f95854e5496254bf67cc258de8d38ff","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"603fc584e9657c2dc92f6beb261e9ef09f95854e5496254bf67cc258de8d38ff","first_computed_at":"2026-07-05T09:58:16.035825Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:58:16.035825Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6bVU+jfmGQAd7bN3yYj/ytNzYDBnJAgMMiMDDyBvja4jFdmB/G5+zbBFVZe15k1jnBRlIztDs3wYQnNYucN9BQ==","signature_status":"signed_v1","signed_at":"2026-07-05T09:58:16.036300Z","signed_message":"canonical_sha256_bytes"},"source_id":"2305.17853","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6773b8574867729f9458f07fd02b57469ea18ae93bda1655a23a6acd3432a97f","sha256:f39ce9c046c2c51f8976e0df980cc8bca35bb8647c20db39b5049977bd3aaff2"],"state_sha256":"3fe8cc36f7d5566dacc68d2d3a87e288df9e714e6451196f3f5be028ec5e9875"}
