This state exists for arbitrarily small interaction in a half-filled honeycomb lattice. Moreover, from the calculations of the topological invariants for the interacting system, it is shown that this gapped state has nontrivial topological characters; this state is the topological Mott insulating state. This result implies the ubiquity of topological Mott insulating phases.","authors_text":"Keisuke Masuda, Shimpei Goto, Susumu Kurihara","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2014-05-15T11:46:44Z","title":"Spontaneous loop-spin current with topological characters in the Hubbard model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1405.3808","kind":"arxiv","version":2},"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":"sha256:2ffdc1957eee280c18ef8027fafb9f1b55a891d7070dc0ae6b754d7793f75c41","target":"record","created_at":"2026-05-18T02:45:55Z","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":"67ee900954b268e440c294fc37b9a60fd5872e75ebf0397e69f34d0d1c8090ee","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2014-05-15T11:46:44Z","title_canon_sha256":"dcf5b377546bc7b3614288239246a4c21a3f7e3ea72228a28a9a2ecf4d77c225"},"schema_version":"1.0","source":{"id":"1405.3808","kind":"arxiv","version":2}},"canonical_sha256":"3ea20b404d44f5bce01cf132af17b57214a6eec77961437462b120686b4085d0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3ea20b404d44f5bce01cf132af17b57214a6eec77961437462b120686b4085d0","first_computed_at":"2026-05-18T02:45:55.619188Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:45:55.619188Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YKOuRQbMP0rrf03z5QBkRIo17gcUCTRQQqAd8NbPh0CM68Yn+F33csZoIUh6CN9boVKCYl361liM2IKRAUDwAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:45:55.619672Z","signed_message":"canonical_sha256_bytes"},"source_id":"1405.3808","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2ffdc1957eee280c18ef8027fafb9f1b55a891d7070dc0ae6b754d7793f75c41","sha256:e4846d2ff31fd17f56e1794d120dd9556a9a22c73679b2c6afbf23a42a17afc3"],"state_sha256":"d172168e895e009f14c2c1e3606cf66c1df6e6d9b59b24829ce2d0c375ec1491"}
