Below a critical temperature Tcr, a coexistence of the polaronic and the bipolaronic solutions is found for the same value of the electron-phonon coupling g in the range gc1(T) < g < gc2(T). In the coexistence region, the system shows a first order phase transition from the bipolaronic to the polaronic states as T decreases at T = Tp(< Tcr), where the double occupancy and the lattice fluctuation together with the anharmonicity of the effective ion potential change discontinuously without any symmetry breaking. The obtained bipolaronic transition seems to be consistent with the rattling transition in the β-pyrochlore oxide KOs2O6.","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.79.093702","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.79.093702","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2010 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":"Fuse, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"7119","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":"983.pdf","filesize":[{"value":"161.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"983.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2122/files/983.pdf"},"version_id":"9d55c1cb-0b8d-4042-8da9-a475409b9114"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"polarons","subitem_subject_scheme":"Other"},{"subitem_subject":"bipolarons","subitem_subject_scheme":"Other"},{"subitem_subject":"bipolaronic transition","subitem_subject_scheme":"Other"},{"subitem_subject":"Holstein model","subitem_subject_scheme":"Other"},{"subitem_subject":"rattling","subitem_subject_scheme":"Other"},{"subitem_subject":"β-pyrochlore oxide","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":"First Order Bipolaronic Transition at Finite Temperature in the Holstein Model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"First Order Bipolaronic Transition at Finite Temperature in the Holstein Model"},{"subitem_title":"First Order Bipolaronic Transition at Finite Temperature in the Holstein Model","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":"2122","relation_version_is_last":true,"title":["First Order Bipolaronic Transition at Finite Temperature in the Holstein Model"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:58.160636+00:00"}
