The isotropic leg interactions J1,a and J1,b between nearest neighbor spins in the legs a and b, respectively, are different from each other. The xy and z components of the uniform rung interactions are denoted by Jr and ΔJr, respectively, where Δ is the XXZ anisotropy parameter. This system has a frustration when J1,aJ1,b < 0 irrespective of the sign of Jr. The phase diagrams on the Δ (0≤Δ<1) versus J1,b plane in the cases of J1,a = − 0.2 and J1,a = 0.2 with Jr = −1 are determined numerically. We employ the physical consideration, the level spectroscopy analysis of the results obtained by the exact diagonalization method and also the density-matrix renormalization-group method. It is found that the non-collinear ferrimagnetic (NCFR) state appears as the ground state in the frustrated region of the parameters. Furthermore, the direct-product triplet-dimer (TD) state in which all rungs form the TD pair is the exact ground state, when J1,a + J1,b = 0 and 0≤ Δ lesssim 0.83. The obtained phase diagrams consist of the TD, XY and Haldane phases as well as the NCFR phase.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_10003_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1742-6596/828/1/012003","subitem_relation_type_select":"DOI"}}]},"item_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://iopscience.iop.org/article/10.1088/1742-6596/828/1/012003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://iopscience.iop.org/article/10.1088/1742-6596/828/1/012003","subitem_relation_type_select":"URI"}}]},"item_10003_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1742-6596","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tonegawa, T."}],"nameIdentifiers":[{"nameIdentifier":"561143","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okamoto, K."}],"nameIdentifiers":[{"nameIdentifier":"561144","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hikihara, T."}],"nameIdentifiers":[{"nameIdentifier":"561145","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, T."}],"nameIdentifiers":[{"nameIdentifier":"561146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂井 徹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561147","nameIdentifierScheme":"WEKO"}]}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Frustrated S = 1/2 Two-Leg Ladder with Different Leg Interactions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Frustrated S = 1/2 Two-Leg Ladder with Different Leg Interactions"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-08"},"publish_date":"2018-04-08","publish_status":"0","recid":"54876","relation_version_is_last":true,"title":["Frustrated S = 1/2 Two-Leg Ladder with Different Leg Interactions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:55:45.933221+00:00"}
