Here we demonstrate that speckle patters obtained by a superposition of randomly arranged sources of Bessel beams can be used to generate hyperunifrom scalar fields. By exploiting laser light tailored with a spatial filter, we experimentally produce (without requiring any computational power) a speckle pattern possessing maxima at locations corresponding to a hyperuniform distribution. By properly filtering out intensity fluctuation from the same speckle pattern, it is p","authors_text":"Daniele Ancora, Diego Di Battista, Giancarlo Ruocco, Giannis Zacharakis, Marco Leonetti","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2018-03-26T12:44:18Z","title":"Hyperuniformity in amorphous speckle patterns"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.09550","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":"sha256:5b49cc0d51f394b1100c12c4c2fa51bd66dcf6d025752a1a1706b8a1c3151845","target":"record","created_at":"2026-05-18T00:11:35Z","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":"c37bc5f2cc9156e76c148f23a878776780a5c950938917bad9b2183537acb7a1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2018-03-26T12:44:18Z","title_canon_sha256":"5e7ebab1b5fab45978756d16f1252738c340508a9dc21541170657d87d9ded9d"},"schema_version":"1.0","source":{"id":"1803.09550","kind":"arxiv","version":1}},"canonical_sha256":"056fd292712a8f2ddd8d49547624263884c8ac8c74a33804776654280d8f925d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"056fd292712a8f2ddd8d49547624263884c8ac8c74a33804776654280d8f925d","first_computed_at":"2026-05-18T00:11:35.134103Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:11:35.134103Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UHIw6UZpj/i5SgefARZoFcSLAu/yc3WlgxtDEehnsvHF718PPtF8VHcCRi74gXeNosl20CSdL0OhPIOEBRN5AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:11:35.134829Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.09550","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b49cc0d51f394b1100c12c4c2fa51bd66dcf6d025752a1a1706b8a1c3151845","sha256:eb0d0fa7b7fdd39a57c92f1a519691427d537bdf809451f651712ee23e3211a3"],"state_sha256":"04d9ac074ec55c006b45de1cf2103a8e92a26ea7e1a476d8336878e68665dac6"}
