It is rather interesting that interplay between the current-carrying scattering state and evanescent modes leads to rich phenomena including resonant backward scattering, perfect tunneling and charge accumulations. In addition, we also find a dual relation between the backscattered conductance and the charge accumulation. At the end, relevance to the experiments is discussed.","authors_text":"Hsiu-Hau Lin, Po-Yao Chang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2009-01-26T23:28:16Z","title":"Conductance through a single impurity in the metallic zigzag carbon nanotube"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.4143","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":"sha256:59284099fec1154f936f3843491938f4ff0246535aa056c4d6ced7021c7b0794","target":"record","created_at":"2026-05-18T02:14:55Z","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":"173435e7a8fa699251a0097b12caa8a33d36adda81676ce2eb7cee07fb0ae689","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2009-01-26T23:28:16Z","title_canon_sha256":"03b0080918ea1f36d54b56049da8ebde634678fbe6ffff27f5ac8469d83317db"},"schema_version":"1.0","source":{"id":"0901.4143","kind":"arxiv","version":1}},"canonical_sha256":"5a0a20f952132e1f23a4b43de22ce8ec90bbcaebe5382fed6af46b71a7acb0b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a0a20f952132e1f23a4b43de22ce8ec90bbcaebe5382fed6af46b71a7acb0b8","first_computed_at":"2026-05-18T02:14:55.752964Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:14:55.752964Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AikWsHA03NJfruZkDl4YrcSijwDi2/plLU11SWY+zciR0hp4s3tlHru8byHEunqH6TybnMZFCBoP/m09T4t0Cg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:14:55.753540Z","signed_message":"canonical_sha256_bytes"},"source_id":"0901.4143","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:59284099fec1154f936f3843491938f4ff0246535aa056c4d6ced7021c7b0794","sha256:d10e340814c3cd69adee1be74e57114fc18eaf1c4ec0ec5574fd75cbe11aefe7"],"state_sha256":"f683c9957d8315b7dfb14451e16cbeec87e883ed672bf85be991989734d26f3a"}
