A particularly enlightening example is the multi-channel Kondo problem. In this review some earlier approaches to the Kondo problem are discussed, the needed material on boundary conformal field theory is developed and then this new method is applied to the multi-channel Kondo problem.","authors_text":"Ian Affleck","cross_cats":["hep-th"],"headline":"","license":"","primary_cat":"cond-mat","submitted_at":"1995-12-12T21:26:13Z","title":"Conformal Field Theory Approach to the Kondo Effect"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/9512099","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:e5b054fa6842b612f7dcb9cc127f5e05b3677baeed859125ec00dc252fa2ee73","target":"record","created_at":"2026-05-18T04:24:26Z","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":"0c39b4cdd2396a6b8499f86b95f2b9d853911b0a2ead60b28d7a4ac23a57878e","cross_cats_sorted":["hep-th"],"license":"","primary_cat":"cond-mat","submitted_at":"1995-12-12T21:26:13Z","title_canon_sha256":"f363425ade5e19ceb2f126f260bd3fe3fa07637a3d8003e6582b80d89f1ac0c5"},"schema_version":"1.0","source":{"id":"cond-mat/9512099","kind":"arxiv","version":1}},"canonical_sha256":"78611c66adf13927599c388857233e77fd36519c0aa1899e9fc3fa6395ec0bf9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"78611c66adf13927599c388857233e77fd36519c0aa1899e9fc3fa6395ec0bf9","first_computed_at":"2026-05-18T04:24:26.295964Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:24:26.295964Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4xdpxJBXxsK3gEvMJGEZ1s4UgHjhEpU0XPrHcrgJJTbwlcDHmiB9TVme8yeYZrN/XyIi7ZPmP6gu1XiqGHQ0BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:24:26.296610Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/9512099","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e5b054fa6842b612f7dcb9cc127f5e05b3677baeed859125ec00dc252fa2ee73","sha256:4a451f975736413b1b9babdea429531713c41d571b66317e64fa56c2b9f5445c"],"state_sha256":"81595e989e082801529930d82926c7b69591db0960a45517a1dd28750ef8b612"}
