We show that the electron-hole pairs can be generated in a controlled way using harmonic and biharmonic time-dependent voltages applied to a quantum contact and obtain the probabilities of the pair creations. For a biharmonic voltage drive, we find that the probability of a pair creation decreases in the presence of an in-phase second harmonic. This accounts for the suppression of the excess noise observed experimentally [Gabelli and Reulet, arXiv:1205.3638] proving that dynamic control ","authors_text":"Mihajlo Vanevic, Wolfgang Belzig","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-10-29T01:30:05Z","title":"Control of electron-hole pair generation by biharmonic voltage drive of a quantum point contact"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1210.7541","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":"sha256:768b4f710de7a32294a0135f252a5682bdbf247284b6803f5b552b46d687b69f","target":"record","created_at":"2026-05-18T03:37:40Z","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":"00f6e4e976b7c100eb549286d69cae8675757c866427aed6c527e59ca877a6f8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-10-29T01:30:05Z","title_canon_sha256":"77715a2d9073616af0b9e8326936e76825eb99cda9d7d149bc1110305d7ac2a3"},"schema_version":"1.0","source":{"id":"1210.7541","kind":"arxiv","version":2}},"canonical_sha256":"090f16d2c585bfaaeeac39612aa3b82887ded0c712d7173b83a84b1ea0d79b53","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"090f16d2c585bfaaeeac39612aa3b82887ded0c712d7173b83a84b1ea0d79b53","first_computed_at":"2026-05-18T03:37:40.704433Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:37:40.704433Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"A8BdRIE9o4SU/pl6U10+pmcJx75PS/AICFIt0aSet9h6Rix+ChYlkhKVB/gHdLMrSyXmSP7+jtB2Aq3WPTTmCg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:37:40.704889Z","signed_message":"canonical_sha256_bytes"},"source_id":"1210.7541","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:768b4f710de7a32294a0135f252a5682bdbf247284b6803f5b552b46d687b69f","sha256:f753d0f818047dbf9fe2b04b6a70d335d64b663c65372201eb761403e49c46ec"],"state_sha256":"be03f9a3121aa5ebb71f61f4d02fe4d638cab7615b31ebf46d165f6887db37bd"}
