As the central hole region increases, i.e., the potential changes from harmonic-like to ring-like, the condensate exhibits a variety of structures, such as triangular stripes, flower-petal patterns, and counter-circling states. We also show that the rotating systems have exotic vortex configurations. In the limit of a quasi-one dimensional ring, the quantum many-body ground state is obtained, which ","authors_text":"Hiroki Saito, Masaya Kato, Shou-Gang Zhang, Wei Han, Xiao-Fei Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2016-10-29T05:32:14Z","title":"Spin-orbit-coupled Bose-Einstein condensates held under toroidal trap"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.09458","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:e95415d9a884946beff21ddae3a0d4cc1a06a12b12296afa630ed272bda0804a","target":"record","created_at":"2026-05-18T00:48:16Z","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":"45669577615be5f5c9de6675aeb4ace6a1c5b20ecc178812788203a702676983","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2016-10-29T05:32:14Z","title_canon_sha256":"f4090c027e29048865b6ce6ffa3b2c53992489e8ecc942c048e71219af9a23f4"},"schema_version":"1.0","source":{"id":"1610.09458","kind":"arxiv","version":1}},"canonical_sha256":"5c75ad759f930c634de897d42974194a36d2e278b53e650368c0ff1b46975ed3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5c75ad759f930c634de897d42974194a36d2e278b53e650368c0ff1b46975ed3","first_computed_at":"2026-05-18T00:48:16.518723Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:16.518723Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CvXE9QCfdcniylKnlNkM78nwrzZPnGkQhISo6pxSOkFpEafUTsHbC3JMziCNL7Ga/7ZSYLQKT25Ta5srtzGoBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:16.519470Z","signed_message":"canonical_sha256_bytes"},"source_id":"1610.09458","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e95415d9a884946beff21ddae3a0d4cc1a06a12b12296afa630ed272bda0804a","sha256:6c1191f43c8132a31f178669ebecc98d8f858ece770abd9bf112200288220859"],"state_sha256":"28a728f3c738ae348723836936e448f481b4f9e6df69153a9713e4c6cd0552a6"}
