The existence of singular points at which the partition function (￡) vanishes is expected in the complex plane. These are called Lee-Yang zeros or Fisher zeros. We investigate the distribution of these singular points using the data obtained by a simulation of two-flavor QCD with p4-improved staggered quarks. The convergence radius of a Taylor expansion of ln ￡ in terms of the chemical potential is also discussed.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"The XXVII Internaitonal Symposium on Lattice Field Theory, July 26-31, 2009 Peking University, Beijing, China","subitem_description_type":"Other"}]},"item_8_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"SISSA"}]},"item_8_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence."}]},"item_8_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18248039","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ejiri, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"169285","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoneyama, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"169286","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":"2019-08-26"}],"displaytype":"detail","filename":"LAT2009_173.pdf","filesize":[{"value":"149.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"LAT2009_173.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/31008/files/LAT2009_173.pdf"},"version_id":"3bb8b3b2-6545-4a73-a7fb-e3822de3b2bc"}]},"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":"Singularities of QCD in the complex chemical potential plane","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Singularities of QCD in the complex chemical potential plane"},{"subitem_title":"Singularities of QCD in the complex chemical potential plane","subitem_title_language":"en"}]},"item_type_id":"8","owner":"1","path":["457","1826"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-23"},"publish_date":"2014-06-23","publish_status":"0","recid":"31008","relation_version_is_last":true,"title":["Singularities of QCD in the complex chemical potential plane"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:01:35.352867+00:00"}
