Here, via combining theoretical analysis and magneto-infrared spectroscopy of an archetypal Weyl semimetal, niobium phosphide, we demonstrate that the coupling between Weyl points can significantly modify the electronic structure of a WSM and provide a new twist to the protected states. These findings suggest that the coupled Weyl points should be considered as the basis for analysis of realistic WSM","authors_text":"D.Smirnov, H.D.Zhou, M.Koshino, S.Moon, Y.Jiang, Z.Jiang, Z.L.Dun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-08T23:06:46Z","title":"Landau quantization in coupled Weyl points: a case study of semimetal NbP"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.03709","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":"sha256:84d8d07f42680dbbf9087a7f651d9ebe5c119c2eda66e77119c0cdc029822a7b","target":"record","created_at":"2026-05-18T00:01:12Z","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":"604bf64b85d5481c4fac4be1822e1c6f5dafa90c2322ba4c9759f5f46ebda060","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-08T23:06:46Z","title_canon_sha256":"f1e6b6a77711f74d1cd52e72663bd2492351f343989911355120dbde24f2c4ea"},"schema_version":"1.0","source":{"id":"1811.03709","kind":"arxiv","version":1}},"canonical_sha256":"84ae8919917ee059f2f83dc7c8e3cf6b94712979db38e1e8b6f28c445755cde3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"84ae8919917ee059f2f83dc7c8e3cf6b94712979db38e1e8b6f28c445755cde3","first_computed_at":"2026-05-18T00:01:12.268130Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:12.268130Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LCkV2Kq3cnlUhfGt7rtFlUJnxspjJeRFRB2T/aCphtYWEBzlX7EtkPEmbXNPfNlZzdiPd2BBsfebP5RPEKf7AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:12.268748Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.03709","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:84d8d07f42680dbbf9087a7f651d9ebe5c119c2eda66e77119c0cdc029822a7b","sha256:2ec3c51ab71023aadd04007e749e349ab4aca06f801ec44f4e774fd1845def55"],"state_sha256":"0d1ef78755d3202f6737daf51a52326e181b7558054d4688f02cce365351366c"}
