The electron system is placed in a circular cylindrical far-infrared photon cavity with a single circularly symmetric photon mode. Our numerical results reveal that the spin ordering of the two-dimensional electron gas in each quantum ring can be influenced or controlled by the electron-photon coupling strength and the energy of the photons. The Coulomb interaction between the electrons is described by a spin-density functional","authors_text":"Andrei Manolescu, Chi-Shung Tang, Hsi-Sheng Goan, Jeng-Da Chai, Nzar Rauf Abdullah, Valeriu Moldoveanu, Vidar Gudmundsson, Vram Mughnetsyan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-11-20T10:20:48Z","title":"Spin-phase transition in an array of quantum rings controlled by cavity photons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2411.13176","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":"sha256:4f299a2c9b2e7fb6861d397dbf19fea0190f6c1fb2a42b358d2363d98c225334","target":"record","created_at":"2026-07-05T10:34:12Z","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":"f87168203807bed9a61102fd9b8b478b893b34d7ba89bbf0141a41c452fe3d6c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-11-20T10:20:48Z","title_canon_sha256":"d47a5d3a5d515be5ad5b2ed246262a219013a236bf7892566214d5974546c0e3"},"schema_version":"1.0","source":{"id":"2411.13176","kind":"arxiv","version":1}},"canonical_sha256":"d6e56b47ef73020ad6b60b6a3e3f9cb3c96080fde030b33a32188bbb25b879a5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d6e56b47ef73020ad6b60b6a3e3f9cb3c96080fde030b33a32188bbb25b879a5","first_computed_at":"2026-07-05T10:34:12.645801Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:34:12.645801Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kLC4Lqqz0v9cdvETerl5OjDX3LN6qL7cwdNNII8DAPohps2QKDtrzvfPU83TJ+fjgEzVgIBWgY+QmUwCRdZMCg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:34:12.646351Z","signed_message":"canonical_sha256_bytes"},"source_id":"2411.13176","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4f299a2c9b2e7fb6861d397dbf19fea0190f6c1fb2a42b358d2363d98c225334","sha256:b156d23d236e0c15769a1c659c0b5a637f5a0cb8ec80543f880df4124a2cb055"],"state_sha256":"cda386263609cc32ad4e5d6ec7630c0092e1dc2083cc1c2e499284e6e836b77b"}
