This approach enables us to obtain the absolute value of Δ, including the prefactor, without ambiguity even in the critical regime of the metal-insulator transition (MIT) where Δ is exponentially small, beyond usual renormalization group methods and/or finite-size scaling approaches. The detailed results of Δ, down to the order of 10−10 near the MIT, are shown as contour lines on the U-V plane.","subitem_description_type":"Abstract"}]},"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.75.113103","subitem_relation_type_select":"DOI"}}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://journals.aps.org/prb/pdf/10.1103/PhysRevB.75.113103","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2007 The American Physical Society"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"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":"Sano, K."}],"nameIdentifiers":[{"nameIdentifier":"37497","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Y."}],"nameIdentifiers":[{"nameIdentifier":"62","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":"75_113103.pdf","filesize":[{"value":"89.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"75_113103.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2503/files/75_113103.pdf"},"version_id":"3a9a1b41-819d-481b-bfa0-26e46c280f8b"}]},"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":"Charge gap in the one-dimensional extended Hubbard model at quarter filling","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Charge gap in the one-dimensional extended Hubbard model at quarter filling"},{"subitem_title":"Charge gap in the one-dimensional extended Hubbard model at quarter filling","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-16"},"publish_date":"2014-04-16","publish_status":"0","recid":"2503","relation_version_is_last":true,"title":["Charge gap in the one-dimensional extended Hubbard model at quarter filling"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:39.800166+00:00"}
