By introducing an effective Hamiltonian depending on the quasiparticle momentum induced by the current, we show that the two-mode topological phase, present in the isolated ladder, is fragile against a finite current flux. To characterize this behavior, we combine bulk topological invariants with real-space diagnostics, including the edge-edge quantum conditional mutual information Iee, which provides an entanglement-ba","authors_text":"Alfonso Maiellaro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-05-21T13:24:11Z","title":"Current-driven reduction of topological protection in multichannel superconductors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.22460","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:fdfbc6916d99ad0eb0825226d3c77bf3e55d4fdd106a6ae8e9c9f857de7c939a","target":"record","created_at":"2026-05-22T01:04:43Z","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":"b11740936a093c4467d3b866dab9e648f83d1ea7018c6c5bb0322154ce288409","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-05-21T13:24:11Z","title_canon_sha256":"2cc40164011f18297b69b8390b38be4a613488d6527e74fea59af9667b65960b"},"schema_version":"1.0","source":{"id":"2605.22460","kind":"arxiv","version":1}},"canonical_sha256":"7f05340c8bc5bcf5c16545ea817bd3315bf493e8bde0e6d765d71595d1724134","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f05340c8bc5bcf5c16545ea817bd3315bf493e8bde0e6d765d71595d1724134","first_computed_at":"2026-05-22T01:04:43.964040Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-22T01:04:43.964040Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"M3ZY38PK1xKLlATl6SWcM4AvDTwrXEFuWDYNqGiMudThywYrietuc9Yyd15+yshQyih6I8uQ7Mq2oHVpnEVbDQ==","signature_status":"signed_v1","signed_at":"2026-05-22T01:04:43.964794Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.22460","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fdfbc6916d99ad0eb0825226d3c77bf3e55d4fdd106a6ae8e9c9f857de7c939a","sha256:1dc1f02243d89635857c611878537b21e83339b85263704232e224941b07fb22"],"state_sha256":"80dac4a8015cbdf92843183f6cc98e8a20e3450f104fcefeed68395f70e9d6fe"}
