In this brief article, we point out that the quantum conservation of the momentum can also fail in flat spacetime, provided the Weyl fermion is coupled to a time-varying homogeneous electric field. This signals a quantum anomaly of the space-translation symmetry, which has not been highlighted in the literature so far.","authors_text":"Jose Navarro-Salas, Pau Beltr\\'an-Palau, Silvia Pla","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-05-16T13:29:43Z","title":"Translational anomaly of chiral fermions in two dimensions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1905.06735","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":"sha256:420579ca7677285c15f4852b680a845cf4f46d6538fd8e74cb2f0779a51f83d2","target":"record","created_at":"2026-05-17T23:45:56Z","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":"067b77c943e6ba2c11728b8e4064f321cf69d81fa2890edef644c421c079d511","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-05-16T13:29:43Z","title_canon_sha256":"4fd88706e83bbf528b43e05be89adf00473b25740742d30bc108ad42fb271c1b"},"schema_version":"1.0","source":{"id":"1905.06735","kind":"arxiv","version":1}},"canonical_sha256":"ae265682a93ac6226a540f3a6200fd17c66c2196bf1343d375c398a6791721a4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ae265682a93ac6226a540f3a6200fd17c66c2196bf1343d375c398a6791721a4","first_computed_at":"2026-05-17T23:45:56.322817Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:56.322817Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0X3Ci4JIfzHN0Buk0K+QRHht7ZQ1jqQ5xGbdLzKhAi15VidhU/I9Sr5/tLPE0PPTVkBlO81Gv/GM+z+FV1nfCA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:56.323377Z","signed_message":"canonical_sha256_bytes"},"source_id":"1905.06735","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:420579ca7677285c15f4852b680a845cf4f46d6538fd8e74cb2f0779a51f83d2","sha256:e1d53b4656e5048848d8d144c4b532f3531995dea5adc0ec443a5319df8064ef"],"state_sha256":"440bb90a1e2caf0165224d17eda8e0b4ba3feb60ff3c93fda62fce882cc843a2"}
