Recently, valley DOF has been introduced into photonic systems, and several valley-Hall photonic topological insulators (PTIs) have been experimentally demonstrated. However, in the previous valley-Hall PTIs, topological kink states only work at a single frequency band, which limits potential applications in multiband waveguides, filters, communications, and so on. To overcome this challenge, here we experimentally demonstrate a valley-Hall PTI, where the topo","authors_text":"Baile Zhang, Fei Gao, Hongsheng Chen, Li Zhang, Mengjia He, Qiaolu Chen, Xiao Lin, Yihao Yang, Zuojia Wang","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-12-28T15:59:22Z","title":"Valley-Hall photonic topological insulators with dual-band kink states"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.11069","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:e984dd3b511b9b1a32c79bfad9599a7eefb06e49370fde05f7521f07c14414bf","target":"record","created_at":"2026-05-17T23:57:16Z","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":"5471624b1e07a1f5241dbe845633ed76ede0f0ddc5bd5773b8de074e6f27147d","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-12-28T15:59:22Z","title_canon_sha256":"9e43f41fc67152bbbb525e3f28c83a79e617cac046b9f8cdee24f2fdedc3892d"},"schema_version":"1.0","source":{"id":"1812.11069","kind":"arxiv","version":1}},"canonical_sha256":"265d7f477be71d8428efde6136ac87b39ccf887887b7782bf5c483f0cc0e7916","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"265d7f477be71d8428efde6136ac87b39ccf887887b7782bf5c483f0cc0e7916","first_computed_at":"2026-05-17T23:57:16.397167Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:16.397167Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qgnMvWsg09DEmdYRMTZW2n5sssktPWfRFYPWPll4ILOuuoHBz+paey6qFsenMKV9D34d8PNkFOcUaavqIHIqAw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:16.397576Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.11069","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e984dd3b511b9b1a32c79bfad9599a7eefb06e49370fde05f7521f07c14414bf","sha256:953e7bce2fd4b98fbfb2dcc1372004411947c34cff57be35967c1e0705d4e511"],"state_sha256":"49f76ef91fe899b7bbcf3cd8ec71de61ce0c1bcb3c17af09dcc35f278c10355f"}
