Unlike prior experiments in SN heterostructures, the nonlocal correlations are mediated not by a superconductor, but by a proximity-coupled normal metal. The nonlocal correlations extend over relatively long length scales in comparison to the superconduncting case. At very low temperatures, we find a reduction in the nonlocal voltage for small applied curren","authors_text":"Sam Davis, Taewan Noh, Venkat Chandrasekhar","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-10-31T18:10:31Z","title":"Nonlocal correlations in a proximity-coupled normal metal"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1210.8426","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":"sha256:1a990872e43e5cd29f4b1e70765575b4f816022803babfc829c5b4bafe3b6587","target":"record","created_at":"2026-05-18T01:53:28Z","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":"dd42e13de90ae5564dcc61d406daeccc83e05e12796c7222c56e2afa560652a4","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2012-10-31T18:10:31Z","title_canon_sha256":"eec0d20489349aa8ba39b96100dd4c23be49743b5795f83f948ac6bc6ef9e44a"},"schema_version":"1.0","source":{"id":"1210.8426","kind":"arxiv","version":2}},"canonical_sha256":"ff653bcd0429d9a2f697d85150ad9dd7c557770294876b53359a8030a52f7feb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ff653bcd0429d9a2f697d85150ad9dd7c557770294876b53359a8030a52f7feb","first_computed_at":"2026-05-18T01:53:28.701371Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:53:28.701371Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"q4SrQBIrAoS2SA7cMs/Qn60k5Uxh1oIObkW84JIzuX6w5chJGCfLUGLbp/u8PmJMvixHzPGu7RwJe7d75nShBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:53:28.702287Z","signed_message":"canonical_sha256_bytes"},"source_id":"1210.8426","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1a990872e43e5cd29f4b1e70765575b4f816022803babfc829c5b4bafe3b6587","sha256:78125d6019b4028bb49a2620bb1340a56f808211b283ae9f675b30f6ebecb474"],"state_sha256":"865d84269da4e8dc80502c9d7da5e8a78213f86ca7ededa97c11a670ead68844"}
