This mechanism exploits the proximity effect with a conventional s-wave superconductor which favors the alignment of the phases of the two-band superconductor which, in the case of s+- pairing, are pi-shifted in the absence of proximity. In the case of a strong proximity such effect can be used to reduce soliton's energy below the energy of a soliton-free state thus making the soliton thermodynam","authors_text":"Alex Levchenko, Valentin Stanev, Victor Vakaryuk, Wei-Cheng Lee","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2012-03-20T19:46:12Z","title":"Phase soliton and pairing symmetry of a two-band superconductor: Role of the proximity effect"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.4554","kind":"arxiv","version":3},"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":"sha256:6783f2bb26aac94355a31c005138950fc9edd426d17e2103fde0a6ce8b6183ed","target":"record","created_at":"2026-05-18T03:39:53Z","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":"f4d0bbaba0ad17b19b7c511e08b2ed013853241fd32570c98e43ebc7d8443ad8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2012-03-20T19:46:12Z","title_canon_sha256":"e88e0d34ace6185c6183303fec1e2962603dae23466f0744e8e60a66ead6617a"},"schema_version":"1.0","source":{"id":"1203.4554","kind":"arxiv","version":3}},"canonical_sha256":"3d7a08e6e24fe0d844f26823060112b756ba1e275c60af3e2eb6282e233c8e2e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3d7a08e6e24fe0d844f26823060112b756ba1e275c60af3e2eb6282e233c8e2e","first_computed_at":"2026-05-18T03:39:53.014877Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:39:53.014877Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"56obE425tNxV5iNcZBKjHd0ShF1HSVj/IF32xd7yCQRubG0UrAWRBFPeva4SoRntfXSGHO/ZjcyfA35Z/qabAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:39:53.015300Z","signed_message":"canonical_sha256_bytes"},"source_id":"1203.4554","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6783f2bb26aac94355a31c005138950fc9edd426d17e2103fde0a6ce8b6183ed","sha256:7f2304e23fce22157e5f1ff44c5957b53475efc98ba3d1041e1b7a3c2575306a"],"state_sha256":"cd4e37e8b225249865d2fd16ddfde65806455d3f1658537191d5103101c0ae50"}
