The theory does not determine the cutoff or how it depends on temperature $T$, and therefore cannot determine the $T$ dependence of the instability field. Here we formulate the microscopic stability problem directly for the vortex-free superconducting state. This removes the core-cutoff ambiguity and determines the instability field $B_s$ over the full temperature range and across all width reg","authors_text":"Takayuki Kubo","cross_cats":["physics.ins-det"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-08-05T06:47:29Z","title":"Microscopic theory of the field-induced instability of the vortex-free state in superconducting thin-film strips"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.04508","kind":"arxiv","version":1},"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":"sha256:25dbd0c2100d95202ecf246a4e38419b555f7d9e5929c68ba24d6b5adc8427c8","target":"record","created_at":"2026-08-06T01:35:45Z","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":"f9a9a5eb6cb5a5ab5a56f1a7071a594939d5bf52d10819599f89e960afb63542","cross_cats_sorted":["physics.ins-det"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-08-05T06:47:29Z","title_canon_sha256":"84757d6eb15011bc1543d20ae4fe827dd3faa4cf4f620dcfaadad40f5e5ec181"},"schema_version":"1.0","source":{"id":"2608.04508","kind":"arxiv","version":1}},"canonical_sha256":"25d62f8c85240c3dd89cede0b39c148ff32ece281a87604b6767f5fd725307a1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"25d62f8c85240c3dd89cede0b39c148ff32ece281a87604b6767f5fd725307a1","first_computed_at":"2026-08-06T01:35:45.013353Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-06T01:35:45.013353Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hgDRJtvuW3VwARxbAZCBWdfMx+QwMcSXdoybledPSoqyqJsiVqBp0QcFi4T+zLdMcmWkSJx1cUuZsjnVRd+eDg==","signature_status":"signed_v1","signed_at":"2026-08-06T01:35:45.014835Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.04508","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:25dbd0c2100d95202ecf246a4e38419b555f7d9e5929c68ba24d6b5adc8427c8","sha256:1ae32862455c18b6485354b6e82c75b2604b47e5b91cf2cc5110211903ef7031"],"state_sha256":"1d9e184430924be50fdb00f7bd0081ef6e64190299b086f01f3678091a255908"}
