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", "download_preview_message": "", "file_order": 0, "filename": "75_113103.pdf", "filesize": [{"value": "89.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 89000.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/26869", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-04-16"}, "publish_date": "2014-04-16", "publish_status": "0", "recid": "2503", "relation": {}, "relation_version_is_last": true, "title": ["Charge gap in the one-dimensional extended Hubbard model at quarter filling"], "weko_shared_id": null}
