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's 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","filename":"19_0007.pdf","filesize":[{"value":"236.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-23"},"publish_date":"2007-04-23","publish_status":"0","recid":"2264","relation_version_is_last":true,"title":["Mott transition in correlated electron systems with orbital degree of freedom"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:07.154478+00:00"}
