We applied the phase re-weighting method to the system to deal with the complex Boltzmann weight. In particular, we succeeded to obtain very precise results thanks to computing the phase factor exactly up to numerical precision with a new algorithm we developed. As a result, we were able to determine the critical point at temporal lattice size 6, which was a goal of the study. Furthermore, we have fixed a curvature of critical line spanned in the quark mass-chemical potential plane.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:26800130, 研究期間(年度):2014-04-01 - 2018-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「有限温度・密度QCDの臨界点探索」課題番号26800130\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26800130/26800130seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域数物科学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052506","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=60577881"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60577881","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26800130/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26800130/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26800130/26800130seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26800130/26800130seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-04-25"}],"displaytype":"detail","filename":"SC-PR-TAKEDA-S-kaken 2018-4p.pdf","filesize":[{"value":"646.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAKEDA-S-kaken 2018-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46172/files/SC-PR-TAKEDA-S-kaken 2018-4p.pdf"},"version_id":"07115515-fb48-4977-9694-8a754698f6e5"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"有限温度・密度QCDの臨界点探索","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有限温度・密度QCDの臨界点探索"},{"subitem_title":"Search for critical point of QCD with finite temperature and density","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2816"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-25"},"publish_date":"2019-04-25","publish_status":"0","recid":"46172","relation_version_is_last":true,"title":["有限温度・密度QCDの臨界点探索"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:49:12.359897+00:00"}
