A methodology is presented to systematically transform a quantum mechanical lattice which exhibits edge states to a phononic lattice, thereby developing a family of lattices with edge states. Parameter spaces with topological phase boundaries in the vicinity of the transformed system are illustrated to demonstrate the robustness to mechanical imperfections. A potential realization in terms of fundamental mechanical building blocks is presented for the h","authors_text":"Marshall Schaeffer, Massimo Ruzzene, Raj Kumar Pal","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-11-23T23:40:31Z","title":"Helical edge states and topological phase transitions in phononic systems using bi-layered lattices"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.07507","kind":"arxiv","version":2},"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:dbc9ac71ba253a80f863577ba64b7407fa0c0aa8e3d324b51a487eaefd9fbc4a","target":"record","created_at":"2026-05-18T01:18:30Z","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":"4b7e2cbc88164792053cec2e5d710cc1f7f92ca3837f84f470a5cd5da9049ec9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-11-23T23:40:31Z","title_canon_sha256":"37417ef24b726726bffd6f177c71fdd7b741b6c04fd2326e262ab01535695097"},"schema_version":"1.0","source":{"id":"1511.07507","kind":"arxiv","version":2}},"canonical_sha256":"c73808ecad3c9c3775a9c39b596c7ebcf353613957b13541ea785549b170be62","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c73808ecad3c9c3775a9c39b596c7ebcf353613957b13541ea785549b170be62","first_computed_at":"2026-05-18T01:18:30.550805Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:18:30.550805Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"z/lqrIy8FrDwgh6pa0o/X6bYxfH7nJoh7JJGGGEa8uLIBUZTf79EQkVT/IEe2V2OKkTp1UOj/UTtmTDrGPIlAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:18:30.551443Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.07507","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dbc9ac71ba253a80f863577ba64b7407fa0c0aa8e3d324b51a487eaefd9fbc4a","sha256:59f7bde620e7bbb3bf3622d996e7d00dcbfb2c747bbe68fd7da1bba7dd4afa0a"],"state_sha256":"ad3f78f5284d57fc8e5c02c13519434c471398d1485eb1e25b6f93c3d1037e6a"}
