The field is conceptually rich, combining the caustic singularities produced in classical gravitational lensing with quantum (wave) interference effects. New techniques have enabled us to overcome previous barriers to computation. Recent developments in radio astronomy present observational opportunities which, while still futuristic, appear promising.","authors_text":"Job Feldbrugge, Neil Turok","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2020-08-03T19:44:16Z","title":"Gravitational lensing of binary systems in wave optics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2008.01154","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":"sha256:4acb524751c930f26510864c4380bc9e02f918d6accca20052830d0e5fc477e2","target":"record","created_at":"2026-07-05T01:24:54Z","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":"b58a5e957546bf6256e5c5d43c8da43a3270380dc77ff2fe28a7813371e414e5","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2020-08-03T19:44:16Z","title_canon_sha256":"f974edcdd25149d28146d438215370785fb4519e129b938255378473a256a913"},"schema_version":"1.0","source":{"id":"2008.01154","kind":"arxiv","version":1}},"canonical_sha256":"d2aa36b943a4a409d3c78eff07d90b62b4b0ac8b0aa3dad72b75126c664b4ef8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d2aa36b943a4a409d3c78eff07d90b62b4b0ac8b0aa3dad72b75126c664b4ef8","first_computed_at":"2026-07-05T01:24:54.074580Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:24:54.074580Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PkRjL8jPOSXAEk48g9MK/bUFxqSwppN3w+aJQu+4tS6quljjmwErdPpWv06X305Py5AffmZ5mnCPnLIULZjrCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T01:24:54.075076Z","signed_message":"canonical_sha256_bytes"},"source_id":"2008.01154","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4acb524751c930f26510864c4380bc9e02f918d6accca20052830d0e5fc477e2","sha256:246fc4ab1d0bc3c4684376d54d63d79bd2e7656033346e43335f4901dab2bef5"],"state_sha256":"b16051c69c067dc04ae032bc034289b4b558e20249d38cc0ddf701f131fdedb4"}
