These effects depend on the relative sign of the gaps for s-wave pairing, and the sign of the Fermi velocities also matters for tunnelling along the nodal direction of d-wave gaps. Experimental probe of such effects could determine both the pairing symmetry and the relat","authors_text":"Da Wang, Qiang-Hua Wang, Yuan Wan","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2009-01-11T15:34:34Z","title":"Theory of tunnelling into a multi-band superconductor: decoherence and interference"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.1419","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":"sha256:02a1ba4bf863361e7dd939ee0d0b00957ffa5118cc3314ef9f4da0995469d0db","target":"record","created_at":"2026-05-18T03:24:08Z","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":"d2194443ac47300d34dcda17d12a90db48e10043f243a669334a87df22884cfd","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2009-01-11T15:34:34Z","title_canon_sha256":"fa9a4ebf445d4a48b3828a24bdab699f81cff07b6ffe0674ee2ca0792263df51"},"schema_version":"1.0","source":{"id":"0901.1419","kind":"arxiv","version":2}},"canonical_sha256":"db57739d8fb6fa51f99cfa4baf0a5a9b1e8b61391227a2b5d2e43e9bf39e533c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"db57739d8fb6fa51f99cfa4baf0a5a9b1e8b61391227a2b5d2e43e9bf39e533c","first_computed_at":"2026-05-18T03:24:08.364160Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:24:08.364160Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bdPXA3HKSVCUVCEYghY2YzGA+8khpS7e4/dNB8GjtR05DclONC6gngDI71y/Gk63Y7vmn7Na9pM+wjcyG+fYDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:24:08.364870Z","signed_message":"canonical_sha256_bytes"},"source_id":"0901.1419","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:02a1ba4bf863361e7dd939ee0d0b00957ffa5118cc3314ef9f4da0995469d0db","sha256:728a95188a75f441bd2e566811fc6309d535202bd2708590e7b098806d478cd2"],"state_sha256":"e009a2a0d3864cf70c2d06b9965fe738d5ab355cd045b8d9709ed26c1812f58d"}
