Based on the Tomonaga-Luttinger liquid theory, we calculate the Luttinger-liquid parameter Kp as a function of electron density n. It is found that superconductivity is realized in parameter region corresponding to the experimental result. We show phase diagram of spin gap on the t2/|t1|-n plane by analyzing the expectation value of twist-operator Zσ in  the spin sector. The spin gap appears in the region with large t2/|t1|, where the phase boundary at half-filling is consistent with that of the known frustrated quantum spin system. The analysis also suggests that the estimated value of the spin gap reaches  100 K in the realistic parameter region of Pr2Ba4Cu7O15-δ.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本物理学会"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1143/JPSJ.76.113701","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.jps.jp/doi/abs/10.1143/JPSJ.76.113701","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2007 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":"7137","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yoshiaki"}],"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":"1000.pdf","filesize":[{"value":"208.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1000.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2129/files/1000.pdf"},"version_id":"4d35ff88-29f2-483c-8b95-5f445339ff8d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"zigzag-chaint–Jmodel","subitem_subject_scheme":"Other"},{"subitem_subject":"spin gap","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical diagonalization","subitem_subject_scheme":"Other"},{"subitem_subject":"superconductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Tomonaga–Luttinger liquid theory","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  and  Spin gap in the zigzag chain t-J model simulating a CuO double chain in  Pr2Ba4Cu7O15-δ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Superconductivity  and  Spin gap in the zigzag chain t-J model simulating a CuO double chain in  Pr2Ba4Cu7O15-δ"},{"subitem_title":"Superconductivity  and  Spin gap in the zigzag chain t-J model simulating a CuO double chain in  Pr2Ba4Cu7O15-δ","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-15"},"publish_date":"2014-04-15","publish_status":"0","recid":"2129","relation_version_is_last":true,"title":["Superconductivity  and  Spin gap in the zigzag chain t-J model simulating a CuO double chain in  Pr2Ba4Cu7O15-δ"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:57.457348+00:00"}
