Furthermore, by tuning the gate voltages of the lateral dots, this device may allow to study the transition from ferromagnetic to antiferromagnetic Kondo effect, a simple case of a Berezinskii-Kosterlitz-Thouless transition. We model the device by three coupled Anderson impurities that we study by","authors_text":"Erio Tosatti, Michele Fabrizio, Pier Paolo Baruselli, Ryan Requist","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2013-02-06T20:25:08Z","title":"Ferromagnetic Kondo effect in a triple quantum dot system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.1499","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":"sha256:0786f281aefc984438582c4071b135f31c22636b6ef26c0cfa450f2eeb041167","target":"record","created_at":"2026-05-18T03:17:44Z","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":"0e4f332bc2058e6e960d1fe82dfa24f461bbe1671954b337e21cf3844899c47c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2013-02-06T20:25:08Z","title_canon_sha256":"b44354c02bbbeb68483cf056b891d14f73a1d7a7841ffa2f7ff4e5cc70c75870"},"schema_version":"1.0","source":{"id":"1302.1499","kind":"arxiv","version":2}},"canonical_sha256":"d1f84cd53ecd0d246503a9dbb3236519c77911b17b7cee14373f650efaf1bff3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d1f84cd53ecd0d246503a9dbb3236519c77911b17b7cee14373f650efaf1bff3","first_computed_at":"2026-05-18T03:17:44.531873Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:17:44.531873Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RQU+nNNDYWBNcad3EI42L5IiyBu8byD2nNI6/dQHENg+P6Ka+LuIo4T5iz0SAyK3cGl2Z/u2HKdtvCGo02X9DA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:17:44.532675Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.1499","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0786f281aefc984438582c4071b135f31c22636b6ef26c0cfa450f2eeb041167","sha256:1b315e9a829ab243f2997187407a98f6b6c60d762973feb3da5d0485f92458bc"],"state_sha256":"5415d0009456763cba6d3b59f20ead281251c97a6f611f7896fdb4cabca4e23e"}
