These interferometers differ from standard interferometers only by the addition of a few quarter waveplates to preserve the polarization of light upon reflection. We show that using current technology, interferometers can probe new regions of axion parameter space up to a couple orders of magnitude beyond current constraints.","authors_text":"Anson Hook, William DeRocco","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-02-20T19:00:07Z","title":"Axion interferometry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.07273","kind":"arxiv","version":2},"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":"sha256:2d7b8440e39a7dc88266423fb3a903d8f8d64c070fde64e0b0df8bbba585554d","target":"record","created_at":"2026-05-18T00:07:35Z","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":"821b0983bc064c3ed35a20402693196d2f98de92c25c6631807652be9cf13b12","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-02-20T19:00:07Z","title_canon_sha256":"7bbdbdc11ee3ded666b8895625b327230b527ece4f7f10c821080adda82ee2cb"},"schema_version":"1.0","source":{"id":"1802.07273","kind":"arxiv","version":2}},"canonical_sha256":"8677a7cd7a0d0c0e84dfe21dc3aa45c70f767af3734b9ab029031547e296df16","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8677a7cd7a0d0c0e84dfe21dc3aa45c70f767af3734b9ab029031547e296df16","first_computed_at":"2026-05-18T00:07:35.078900Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:07:35.078900Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Cbk/GSNJVv44xgeEPvGNlO0ImcHjEcW9D3t+q3kzT728vDJ4j6bxTIE2BZJNSXzp4TFxK/kwn8BUVosLxWT4Cg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:07:35.079498Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.07273","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2d7b8440e39a7dc88266423fb3a903d8f8d64c070fde64e0b0df8bbba585554d","sha256:6e175d2d12f391fd4bfc5bc5bd573c5b2e4cab9cf7d06bf1054e80cae139a486"],"state_sha256":"94803d3c11b78a562daae179c07a553d6ad0b5bad43a830c9cd11825abacfd78"}
