To investigate its superconductivity, we employ the d-p double chain model where the tight-binding parameters are determined so as to fit a band structure in the local density approximation (LDA). On the basis of the Tomonaga-Luttinger liquid theory, we obtain a phase diagram that includes the superconducting phase in the weak coupling limit. We also calculate the Luttinger liquid parameter K_ρ as a function of the electron density n using the Hartree-Fock approximation. With increasing n from quarter filling, K_ρ increases and then exceeds 1/2 when the superconducting correlation becomes most dominant. K_ρ has a maximum at an optimal density between quarter- and half-filling. These results are consistent with the experimental observation.","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":"The Physical Society of Japan"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1143/JPSJ.74.2885","subitem_relation_type_select":"DOI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The Physical Society of Japan"}]},"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":"AA00704814","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00319015","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sano, Kazuhiro"}],"nameIdentifiers":[{"nameIdentifier":"7139","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"62","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Yuh"}],"nameIdentifiers":[{"nameIdentifier":"7141","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_0003.pdf","filesize":[{"value":"205.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19_0003.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2130/files/19_0003.pdf"},"version_id":"32898108-942e-4944-a74f-f51d640946e3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Pr2Ba4Cu7O15-σ","subitem_subject_scheme":"Other"},{"subitem_subject":"CuO double chain","subitem_subject_scheme":"Other"},{"subitem_subject":"Superconductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Tomonaga-Luttinger liquid","subitem_subject_scheme":"Other"},{"subitem_subject":"d-p model","subitem_subject_scheme":"Other"}]},"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":"Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_<15-δ> on the basis of Tomonaga-Luttinger liquid Theory","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_<15-δ> on the basis of Tomonaga-Luttinger liquid Theory"},{"subitem_title":"Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_<15-δ> on the basis of Tomonaga-Luttinger liquid Theory","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":"2130","relation_version_is_last":true,"title":["Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_<15-δ> on the basis of Tomonaga-Luttinger liquid Theory"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:56.412590+00:00"}
