2) increasing the transport channel length, and counterintuitively, increasing the acoustic wavelength as well, would improve the quantization accuracy, and very promisingly up to 0.01ppm as required for a quantum current standard.","authors_text":"Jie Gao, Xiang-Bai Chen, Xiang-Song Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2008-07-16T15:04:08Z","title":"On the quantization accuracy of the acoustoelectric current"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0807.2586","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":"sha256:21d852d539055ec9de4c43e062b7c6ce3b1540892e3cf89ef156c9fe24948ab5","target":"record","created_at":"2026-05-18T04:21:00Z","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":"2d0f2393e64e5e6303a40d272c2996603ce27cf8ce489fd334e8e7e31992286b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2008-07-16T15:04:08Z","title_canon_sha256":"6878fd2281b5fd5da6046012494876ca16786a72a9adab062aac1532d3b44993"},"schema_version":"1.0","source":{"id":"0807.2586","kind":"arxiv","version":1}},"canonical_sha256":"de08c3bddecb414d7450c0440cb5849df6f1c32f807542254a275a4a3bc94913","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"de08c3bddecb414d7450c0440cb5849df6f1c32f807542254a275a4a3bc94913","first_computed_at":"2026-05-18T04:21:00.811029Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:21:00.811029Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O/A75QvF88TUQiz2D0Mw4uVYZn4UNyfUNKsnvTpWwMAL+blrRGKf+TuMNeXKZSqq/zIvDr+GHHh5yeKCsG66CA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:21:00.811534Z","signed_message":"canonical_sha256_bytes"},"source_id":"0807.2586","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:21d852d539055ec9de4c43e062b7c6ce3b1540892e3cf89ef156c9fe24948ab5","sha256:b95945100193dfcaafabb642c4d319464d954d206f2db2dc55cb1d9cc0397182"],"state_sha256":"98a60a775dd0cb988fc6169e21eb24ddd405727b4eb72553c57b2fc4633cd526"}
