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", "download_preview_message": "", "file_order": 0, "filename": "19_0003.pdf", "filesize": [{"value": "205.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 205200.0, "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_\u003c15-δ\u003e 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_\u003c15-δ\u003e on the basis of Tomonaga-Luttinger liquid Theory"}, {"subitem_title": "Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_\u003c15-δ\u003e on the basis of Tomonaga-Luttinger liquid Theory", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/1148", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-23"}, "publish_date": "2007-04-23", "publish_status": "0", "recid": "2130", "relation": {}, "relation_version_is_last": true, "title": ["Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_\u003c15-δ\u003e on the basis of Tomonaga-Luttinger liquid Theory"], "weko_shared_id": null}
