The effective Hamiltonian derived from the two-orbital Hubbard model is analyzed by the mean-field approximation. Applying H to the low-spin (LS) phase induces the excitonic insulating phase, as well as the spin-state ordered phase where the LS and high-spin (HS) states are ordered alternately. In the case where H is applied to the HS phase, a reentrant transition for the HS phase appears. A rich variety of the phase diagrams are attributed to the spin-state degree of freedom and thei","authors_text":"Eriko Mizoguchi, Joji Nasu, Makoto Naka, Sumio Ishihara, Taro Tatsuno","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2016-06-06T10:25:45Z","title":"Magnetic field effects in a correlated electron system with spin-state degree of freedom - Implication of an excitonic insulator -"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.01681","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":"sha256:50ff3b1e65f1eb6f151f51f4b1928c699bfa488783d78bb16e63792624b9b84a","target":"record","created_at":"2026-05-18T01:09:57Z","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":"324a0efe501d36c2bac294b20f6f40e19fa8c0cd4723711a2c75d5397b6ca588","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2016-06-06T10:25:45Z","title_canon_sha256":"732d1e491075dc73b6bbafde87dfd207bbbb603fbb8e383872f01d5a303b9db8"},"schema_version":"1.0","source":{"id":"1606.01681","kind":"arxiv","version":1}},"canonical_sha256":"ed16fe10542bb6766af952ba845a08d87d2ac54be8a58f470a1b5bf022fc3226","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ed16fe10542bb6766af952ba845a08d87d2ac54be8a58f470a1b5bf022fc3226","first_computed_at":"2026-05-18T01:09:57.357735Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:09:57.357735Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rFxR9rKwnZx+ZqX3yATNcU2deBv/qKDnkyqQMnPyZOla7reygTMlUhmlvkZ5naJ417aRm0oOLXTeGyvTJ4BiAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:09:57.358364Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.01681","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:50ff3b1e65f1eb6f151f51f4b1928c699bfa488783d78bb16e63792624b9b84a","sha256:fa70b053d7cb4a7768140c13ec60fa9baccef8bf717c23935e057f9edfd5f9ec"],"state_sha256":"069e06cf604fa47e276ea1070a6809feed5c59e394aea9edd18595748b8d2752"}
