This Berry curvature can be induced by Weyl points and gapped nodal lines. One of the possible mechanisms takes place in systems with a symmetry group where mirror planes lead to protected nodal line structures. When these mirror symmetries are broken, e. g. via fixing a magnetization direction, a gap in the former nodal line can create Weyl points and a large Berry curvature along the gapped lines. In this work we study this effect in a minimal effective model a","authors_text":"Claudia Felser, Jonathan Noky, Yan Sun","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-12T12:03:26Z","title":"Large anomalous Hall and Nernst effect from nodal line symmetry breaking in Fe$_2$MnX (X=P,As,Sb)"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.04680","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":"sha256:6228d7b2dd993571bbe588293d5436562b62acdc6fdc96b0934061c845937985","target":"record","created_at":"2026-05-17T23:48:31Z","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":"e21053d72e1db47345b15e51bb525e300918dcd57a0f948a33e8e87f6323c374","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-12T12:03:26Z","title_canon_sha256":"8bdf0e1536bfc326ccca8939e109055d6697fcb23f631c09db23ab15c3148592"},"schema_version":"1.0","source":{"id":"1811.04680","kind":"arxiv","version":1}},"canonical_sha256":"6a6af689db8e8049e7f90fb18ff1c94c8b433d7571e11a7978481f9430e51b13","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6a6af689db8e8049e7f90fb18ff1c94c8b433d7571e11a7978481f9430e51b13","first_computed_at":"2026-05-17T23:48:31.597579Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:48:31.597579Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Vx02iuX6ZfiFAL+IGdoEiS5PMYgFUbhR7VxHXn9mci6zMSv+YzoOSCLrCb9LoBeEyyLmKhXe89tOfr7AUgCHDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:48:31.598935Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.04680","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6228d7b2dd993571bbe588293d5436562b62acdc6fdc96b0934061c845937985","sha256:7357281ad8b527a89343465abf7a0c15281b7cd8ed2ff35c75e4451cfab3af47"],"state_sha256":"b13d517a24e24fb826e99447aa30393d5c6cf821635ddcdaeadc5409501d5102"}
