Our results reveal that the coupling of adjacent edge modes sets in at a step{to{step distance $d_{ss} < 25$ nm, resulting in a characteristic splitting of a single peak at the Dirac point in tunneling spectra. Whereas the energy splitting exponentially increases with decreasing $d_{ss}$ for single-atomic steps running almost parallel, we find no sp","authors_text":"Andrzej Szczerbakow, Artem Odobesko, Johannes Jung, Matthias Bode1, Robin Boshuis, Tomasz Story","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.str-el","submitted_at":"2021-05-17T12:37:25Z","title":"A Systematic Investigation of the Coupling between One-Dimensional Edge States of a Topological Crystalline Insulator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2105.07774","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:db1639918591c09e5dea4943204414342ec66a4253cd11dc94563d7f5842ae4d","target":"record","created_at":"2026-07-05T02:53:44Z","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":"5a1ededee94331bc06e3c772cc4516999cb228cf61877c9f7735e47507def59e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.str-el","submitted_at":"2021-05-17T12:37:25Z","title_canon_sha256":"a32c222f6c00d3937058591a317e5e67da91b51489199d4760088020246f515a"},"schema_version":"1.0","source":{"id":"2105.07774","kind":"arxiv","version":1}},"canonical_sha256":"46a4ebe6e1185a50c5dff64891172589f216ae52e2cdafcc25949134acf44f4f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"46a4ebe6e1185a50c5dff64891172589f216ae52e2cdafcc25949134acf44f4f","first_computed_at":"2026-07-05T02:53:44.105438Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:53:44.105438Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"emx580lNMClmreNLxaWsGXbO7UE3L2Wh8fvEd2omFsQ1OfgOEKG+8m+mrja1/iXQ+Fk3Z2o26XTX4xRL8i32AA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:53:44.105894Z","signed_message":"canonical_sha256_bytes"},"source_id":"2105.07774","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:db1639918591c09e5dea4943204414342ec66a4253cd11dc94563d7f5842ae4d","sha256:71c80ba269a2004f66b17c45402ade2e86c8ce571a4973385e92ca65c4293313"],"state_sha256":"e549bdae1a0c6d52389812805b5ea4a091760f6a3a3eea9237d8334444aef23d"}
