The method allows for an efficient and reliable determination of the critical interaction Uc for any integer filling n and different M at zero temperature. For half-filling a linear dependence of Uc on M is found. Inclusion of the (full) Hund\u0027s rule exchange J results in a strong reduction of Uc. The transition turns out to change qualitatively from continuous for J=0 to discontinuous for any finite J. This result is confirmed using the exact-diagonalization method for M=2.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "62", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "大野, 義章"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1103/PhysRevB.67.035119", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "The American Physical Society"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11187113", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "10980121", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ono, Yoshiaki"}], "nameIdentifiers": [{"nameIdentifier": "62", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ralf, Bulla"}], "nameIdentifiers": [{"nameIdentifier": "7688", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Michael, Potthoff"}], "nameIdentifiers": [{"nameIdentifier": "7689", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "19_0007.pdf", "filesize": [{"value": "236.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 236300.0, "url": {"label": "19_0007.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2264/files/19_0007.pdf"}, "version_id": "2e8fec31-c38a-4729-88bf-b0e3c81dff55"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Mott transition in correlated electron systems with orbital degree of freedom", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Mott transition in correlated electron systems with orbital degree of freedom"}, {"subitem_title": "Mott transition in correlated electron systems with orbital degree of freedom", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/1147", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-23"}, "publish_date": "2007-04-23", "publish_status": "0", "recid": "2264", "relation": {}, "relation_version_is_last": true, "title": ["Mott transition in correlated electron systems with orbital degree of freedom"], "weko_shared_id": null}
