The discussion of this instability is based on the analysis of the effective Coulomb interaction and the assumption that the system behaves like a two dimensional Fermi liquid. It is shown that this superconducting instability appears in the p-wave channel (like in the pure QED$_{3}$ case) and an expression for the critical temperature of the transition is provided.","authors_text":"Alberto Cortijo","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2010-12-09T14:11:47Z","title":"A Superconducting instability in the surface of a topological insulator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1012.2008","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":"sha256:12005ce39d8aa705af28955766e85634f01339fc83eca315d5be2957f2b69f47","target":"record","created_at":"2026-05-18T04:25:38Z","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":"25a3beee7ce012091c84cb797b4a743b58cc67bd8c9f3716c165fcc756de17a9","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2010-12-09T14:11:47Z","title_canon_sha256":"3f3b8471e4f418485c05ad944d8162a9a543050b5929b95d8d47e427c990667f"},"schema_version":"1.0","source":{"id":"1012.2008","kind":"arxiv","version":2}},"canonical_sha256":"59ae5819bbd4a6bbb4e912a647a14bae0ad76d369131b264cbc29d853d0ec448","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"59ae5819bbd4a6bbb4e912a647a14bae0ad76d369131b264cbc29d853d0ec448","first_computed_at":"2026-05-18T04:25:38.894515Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:25:38.894515Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VXNj7CX2BtHo1D/Gsny7k81i8cffbUPKlTmO8qvwEDb/IkI/ySBPMqNvnYCJfdKSjYg6YgpZthUl2ZJNrMofCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:25:38.894937Z","signed_message":"canonical_sha256_bytes"},"source_id":"1012.2008","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:12005ce39d8aa705af28955766e85634f01339fc83eca315d5be2957f2b69f47","sha256:ca58d93377316bc3db639d6d791d99469f7a2b15c35ec5bb68ac342236c2f6a3"],"state_sha256":"6972f6a9f4d32731f6f57d91a58dc04a3ca8970f6afcbe93312b1e2b1b352d13"}
