Using Landauer-Buttiker formula, we have found that the polarization direction and phase of transmitted electrons can be controlled by both the magnetic field and RSOC. A device to generate a spin-polarized conductance in a polygon with an arbitrary number of sides is discussed. This device would permit precise control of spin and selectively provide spin filtering for either spin up or spin down si","authors_text":"Han-Zhao Tang, Jian-Jun Liu, Li-Xue Zhai, Man Shen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2014-02-17T02:09:55Z","title":"Effects of Rashba spin-orbit coupling and a magnetic field on a polygonal quantum ring"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.3868","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":"sha256:0cdc6e1dddb3800461b24de7a172cac7967a16af21a33e7949dc95bbcd21a698","target":"record","created_at":"2026-05-18T01:44:37Z","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":"91352a62794f7cd0a5dc7edad9c9a30341d883e6e66d2fd944c6a15c75d6ef6c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2014-02-17T02:09:55Z","title_canon_sha256":"f7dc8c18b3468d529188a0546f78fb35916a11e921142e16e2bf29dc4b961a77"},"schema_version":"1.0","source":{"id":"1402.3868","kind":"arxiv","version":1}},"canonical_sha256":"9b8d9562691803e5a84df19fe4246d9c2fa46b2284c0e83b6dfc15e5e7bf51a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9b8d9562691803e5a84df19fe4246d9c2fa46b2284c0e83b6dfc15e5e7bf51a9","first_computed_at":"2026-05-18T01:44:37.494937Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:44:37.494937Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3FzK0DPUdLwxqU4iRN+RGESS2EiHJGev5OkQhg23tFDuOAhavSob06X7eO6V+dBczqpfzc5T0VbP36HSRw6ZDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:44:37.495696Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.3868","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0cdc6e1dddb3800461b24de7a172cac7967a16af21a33e7949dc95bbcd21a698","sha256:f515ba1da65599de6ca31389327741b4f44fb6811959abaed0850d43bc37dac5"],"state_sha256":"1d7ef4fe5c3c9559a37d2600c12defa8a99749de13a93ebd70da80db822967e9"}
