Based on the Tomonaga–Luttinger liquid theory, we calculate the Luttinger liquid parameter Kρ as a function of the electron density n. It is found that superconductivity is realized in the parameter region, which is in accordance with experimental results. We show the phase diagram of a spin gap in the t2/|t1|–n  plane by analyzing the expectation value of the twist operator Zσ  in the spin sector. The spin gap appears in the region with a 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_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Physical Society of Japan"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1143/JPSJ.76.113701","subitem_relation_type_select":"DOI"}}]},"item_10001_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_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-9015","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_70":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Journal Article / 学術雑誌論文"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sano, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"21623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ōno, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"21624","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":"2017-02-18"}],"displaytype":"detail","filename":"40A13561.pdf","filesize":[{"value":"332.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"40A13561.pdf","url":"https://mie-u.repo.nii.ac.jp/record/8396/files/40A13561.pdf"},"version_id":"072420f1-7a1f-4e8c-a8a1-6d14506c7279"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"zigzag-chain t-J model","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_language":"en"}]},"item_type_id":"10001","owner":"15","path":["639"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-25"},"publish_date":"2010-06-25","publish_status":"0","recid":"8396","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":"15","weko_shared_id":-1},"updated":"2023-10-16T02:35:11.314714+00:00"}
