Periodic linear chains are side-attached to a Fibonacci chain, giving it the shape of an aperiodic comb. The effect of the side-attachments on the usual Cantor set energy spectrum of a Fibonacci chain is analyzed using the Greens function technique. A special correlation between the coupling of the side-attached chain with the Fibonacci chain and the inter-atomic coupling of the Fibonacci chain results in a dramatic triggering of the fragme","authors_text":"Biplab Pal","cross_cats":["cond-mat.dis-nn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2014-01-17T09:41:28Z","title":"Absolutely continuous energy bands and extended electronic states in an aperiodic comb-shaped nanostructure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.4284","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":"sha256:1aff1f90f85f41e61f685bb00e5c50a68e5e76b816ff43289eb331af1c2dedce","target":"record","created_at":"2026-05-18T02:47:22Z","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":"aad7a3b050e0fca283bf23a75cdcc152e421a6ea2673436abc7f475d2114f793","cross_cats_sorted":["cond-mat.dis-nn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2014-01-17T09:41:28Z","title_canon_sha256":"9102813a1fa1e2823dae76bf9ebd6f47ca6ca9646bef9cf2a6ece9ef438a485d"},"schema_version":"1.0","source":{"id":"1401.4284","kind":"arxiv","version":1}},"canonical_sha256":"8ea4f894dff4bdcf304a91a9e6e91ad0509d5a6f0dcb1c909bcc9cee6bb6ad88","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8ea4f894dff4bdcf304a91a9e6e91ad0509d5a6f0dcb1c909bcc9cee6bb6ad88","first_computed_at":"2026-05-18T02:47:22.991280Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:47:22.991280Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oZcFjRL7c39aIsdGtbPOtcf4qhZq1MeL0K/recs+0fT8gN69a2Fyq9L8B1UCAvSwQWU6vGI82hUFvu3nkf91Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:47:22.991910Z","signed_message":"canonical_sha256_bytes"},"source_id":"1401.4284","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1aff1f90f85f41e61f685bb00e5c50a68e5e76b816ff43289eb331af1c2dedce","sha256:3a6627a79698f8369687eb20dd81f1ffe30a0e191a2a92a66759381a7696017b"],"state_sha256":"e709e627801006901c0fc2557abad4a5f25769efc24e6fd2013af564ce015705"}
