Charge density waves (CDW) is found to be the natural consequence of the chiral symmetry breaking. The phase mode of this charge density wave state is identified as the axion, which couples to electromagnetic field in the topological $\\theta{\\bf E}\\cdot{\\bf B}$ term. One of our main results is that the \"axion strings\" can be realized as the (screw or edge) dislocations in the charge density wave, which provides a simple physical picture for the ","authors_text":"Shou-Cheng Zhang, Zhong Wang","cross_cats":["hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2012-07-22T14:58:46Z","title":"Chiral anomaly, Charge Density Waves, and Axion Strings from Weyl Semimetals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1207.5234","kind":"arxiv","version":3},"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:f76cf525463965e0f03f46b43b4a42026c1c644ee529980581e44cf5391a1fcb","target":"record","created_at":"2026-05-18T03:28:05Z","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":"35d6dc3701fd9cc91af3304463c77a218e6f4fac7b70a14b76a66f4abca88623","cross_cats_sorted":["hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2012-07-22T14:58:46Z","title_canon_sha256":"4481884c63ed1288e85529606f5d9f47bd3eaeccce7607436acd4d7039861894"},"schema_version":"1.0","source":{"id":"1207.5234","kind":"arxiv","version":3}},"canonical_sha256":"9a1f7e9ebf9db552b861a1a4530bb96f3dc566ff3d5c1f60a30a1039c9d9b0dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a1f7e9ebf9db552b861a1a4530bb96f3dc566ff3d5c1f60a30a1039c9d9b0dd","first_computed_at":"2026-05-18T03:28:05.895686Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:28:05.895686Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WcgHysNMWNhqdCal0WQU+9zcjhS1jFpk+1lvpadUiV9QevuXXg+0X+XsfAOqvSxq1u1K/DqEftKp9Wv2tz66AA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:28:05.896775Z","signed_message":"canonical_sha256_bytes"},"source_id":"1207.5234","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f76cf525463965e0f03f46b43b4a42026c1c644ee529980581e44cf5391a1fcb","sha256:2d868730d62d3ba5d237a7f144f83a4fcb526ed67110443d8b142354465f01ba"],"state_sha256":"c0c6848f3d70e895cb4d59f5a553146ebd4264aae65e500ed372f5407760c92f"}
