The time-evolving field value as well as the perturbation of the scalar generically induce $B$-mode polarization. Future CMB data will find either a cosmic parity violation in temperature-polarization correlation due to the field value, or perturbation-induced $B$-mode polarization that is almost indistinguishable from that generated by gravitational lensing or primordial gravitational waves.","authors_text":"Guo-Chin Liu, Kin-Wang Ng, Seokcheon Lee","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-07-24T05:47:25Z","title":"Imprint of Scalar Dark Energy on Cosmic Microwave Background Polarization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.6298","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":"sha256:0484fde5103c266e06a9b9b9998e364fb615d3aa7cc4ff9168e2eaef65a80a1f","target":"record","created_at":"2026-05-18T02:55:39Z","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":"6e4acd90a1c0b94afd7501ac61d28c2414db3bf8b6843392a011f51df61cb8fc","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-07-24T05:47:25Z","title_canon_sha256":"eb24312743a1e8c793848b97227a4364c1f3965fc48e406a3b1ab5324344108e"},"schema_version":"1.0","source":{"id":"1307.6298","kind":"arxiv","version":2}},"canonical_sha256":"32ee3ae15c041e114795a643fd1c6521ab6410cd082ce4e4c6370113c530a302","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"32ee3ae15c041e114795a643fd1c6521ab6410cd082ce4e4c6370113c530a302","first_computed_at":"2026-05-18T02:55:39.058099Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:55:39.058099Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uzu+ES935BlvYPatuLOpbYLsvx8w8ZhXi0XhGM0ZoBqzJFjt6oZs3aVJ+XzX1vo/WoOzc9mfVeDD726HIAbwBg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:55:39.058892Z","signed_message":"canonical_sha256_bytes"},"source_id":"1307.6298","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0484fde5103c266e06a9b9b9998e364fb615d3aa7cc4ff9168e2eaef65a80a1f","sha256:a503ff320f15d4a0f6cf32d29fdf9fe347fc8ff27c67d934eadca57c2c1cece1"],"state_sha256":"2008376ea5c0931f5fdbfab8324245b9c965022090ab136d06fca49276bdfd88"}
