At first, an infinitesimal doping from the half-filling is focused on and the momentum-dependent charge susceptibility κ(k)=dn(k)/dμ is calculated at a finite temperature. At the temperature Tnot, vert, similart2/U, it shows peak structure at (±π/2,±π/2) on the FS (line). It is consistent with the mean-field prediction of the d-wave pairing state or the staggered flux state. This momentum-dependent structure disappears at the high temperature T≈U. After summarizing the results of the half-filling case, we also discuss the effects of the doping on the momentum-dependent charge susceptibility. The anisotropic structure at half-filling fades out with sufficient doping.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_8_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_8_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/S0022-3697(02)00057-4","subitem_relation_type_select":"DOI"}}]},"item_8_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2002 Published by Elsevier Science Ltd.","subitem_rights_language":"en"}]},"item_8_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-3697","subitem_source_identifier_type":"PISSN"}]},"item_8_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00704949","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Otsuka, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"60179","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morita, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"60180","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"初貝, 安弘","creatorNameLang":"ja"},{"creatorName":"ハツガイ, ヤスヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"HATSUGAI, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"110","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80218495","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000080218495"},{"nameIdentifier":"0000000537","nameIdentifierScheme":"筑波大学研究者総覧","nameIdentifierURI":"http://trios.tsukuba.ac.jp/researcher/0000000537"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-19"}],"displaytype":"detail","filename":"JPCS_63-6-8.pdf","filesize":[{"value":"126.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/16930/files/JPCS_63-6-8.pdf"},"version_id":"1e566654-a47e-46ea-96eb-a13f313fb0d5"}]},"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":"other","resourceuri":"http://purl.org/coar/resource_type/c_1843"}]},"item_title":"Correlation effects on the Fermi surface of the two-dimensional Hubbard model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Correlation effects on the Fermi surface of the two-dimensional Hubbard model","subitem_title_language":"en"}]},"item_type_id":"8","owner":"188","path":["483","677"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-10-31"},"publish_date":"2008-10-31","publish_status":"0","recid":"16930","relation_version_is_last":true,"title":["Correlation effects on the Fermi surface of the two-dimensional Hubbard model"],"weko_creator_id":"188","weko_shared_id":-1},"updated":"2024-03-22T05:07:12.756499+00:00"}
