The two-leg ladder consists of the two lowest orbital states of the optical lattice and the cross inter-leg links are generated via two-photon resonant coupling between the orbitals by periodic lattice shaking. The characteristic pseudo-spin winding in the topologically non-trivial bands of the ladder system is demonstrated using momentum-resolved Ramsey-type interferometric measurements. We discuss a two-tone driving method to extend the inter-leg link","authors_text":"Jeong Ho Han, Jin Hyoun Kang, Yong-il Shin","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-02-27T02:04:37Z","title":"Topological Creutz Ladder in a Resonantly Shaken 1D Optical Lattice"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.10304","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":"sha256:9f18d1d62e085693ac33ed045c00115491e04f78930af6c6f54947583c1bb1ee","target":"record","created_at":"2026-07-05T00:39:10Z","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":"ff15426b7bc6e1fc08e8c4ad2fe821729c7287bf3970f838cfc2d7ca810482fc","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-02-27T02:04:37Z","title_canon_sha256":"74634cf6e969b1f14320e11b7abca65f9771fd888b4823abdec881e5e1197d46"},"schema_version":"1.0","source":{"id":"1902.10304","kind":"arxiv","version":1}},"canonical_sha256":"9cf8d72e51808ef0fef6d8f1af03b28953b3fc53ef7538ddc43438621817e809","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9cf8d72e51808ef0fef6d8f1af03b28953b3fc53ef7538ddc43438621817e809","first_computed_at":"2026-07-05T00:39:10.876118Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:39:10.876118Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"M9hF8C4FEcwcsIZMHBp740svCOZCZdSSkeAZ36C969RmKR0sEM7ARbSIxd4Qtn2afxhsUCDXAyflXsV/E1IUCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:39:10.876647Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.10304","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9f18d1d62e085693ac33ed045c00115491e04f78930af6c6f54947583c1bb1ee","sha256:f21bbb960776be13d969a67f80a1df74c86f15a34767177beae8e6a95423cd60"],"state_sha256":"40e5c3ba6be0852159f385e5de3c501c8754e6e28bb11cb80ab7dd725b07b764"}
