It is obtained though the interference pattern of two counterpropagating beams: one of the beam is a standard gaussian beam, while the other one is a hollow beam obtained through a setup with two conical lenses. The resulting lattice is shown to have a high filling rate and a good confinement, so that it could be loaded directly from a MOT with applications in the domain of quantum computing, or with a Bose-Einstein condensate, which would have in this case a 1D ring geometry.","authors_text":"Daniel Hennequin, Philippe Verkerk","cross_cats":["quant-ph"],"headline":"","license":"","primary_cat":"physics.atom-ph","submitted_at":"2003-06-20T19:18:45Z","title":"An Optical Lattice of Ring Traps"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"physics/0306155","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":"sha256:594d9780246692e1c3a28984973b8e6ddf6fe433f049a7c35ccfa2d8f853eed4","target":"record","created_at":"2026-07-04T14:43:58Z","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":"d561f0a459280e9af53177dfbbc4f8122a1cbaedbffe196568b9f1b51b1cba74","cross_cats_sorted":["quant-ph"],"license":"","primary_cat":"physics.atom-ph","submitted_at":"2003-06-20T19:18:45Z","title_canon_sha256":"5b46362b93fd3c2ba8db979ee11cf2eec60fce2eea437ec25629be55a868f7dc"},"schema_version":"1.0","source":{"id":"physics/0306155","kind":"arxiv","version":1}},"canonical_sha256":"d2441aa7b7f993bacdef2bbec3c6b5a08f0257e94034d90a12cd88f32d701883","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d2441aa7b7f993bacdef2bbec3c6b5a08f0257e94034d90a12cd88f32d701883","first_computed_at":"2026-07-04T14:43:58.197733Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:43:58.197733Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Eu/dNM3lnGsq/qnEySuVkfVpO3eMUZk1nUNksEnYZfnKUNwgGf9PMMy7xkr7UFXVkwRRrNA5aNFrco74PGxfBg==","signature_status":"signed_v1","signed_at":"2026-07-04T14:43:58.198173Z","signed_message":"canonical_sha256_bytes"},"source_id":"physics/0306155","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:594d9780246692e1c3a28984973b8e6ddf6fe433f049a7c35ccfa2d8f853eed4","sha256:53c0c6feb82fabd4103e68f32424e71bb2aa0235c7d51b5f03f52d67a63127d0"],"state_sha256":"ed5e3a2379909784925f99caa7763639182f94de4e772101c341c19b5924cc43"}
