We propose a method to calculate the canonical partition function by fixing the total quark number introducing approximations allowed in the low density region. An effective potential as a function of the quark number density is discussed from the canonical partition function. We analyze data obtained in a simulation of two-flavor QCD using p4-improved staggered quarks with bare quark mass m/T=0.4 on a 16 3 ×4 lattice. The results suggest that the finite density phase transition at low temperature is of first order.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevD.78.074507","subitem_relation_type_select":"DOI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2008 American Physical Society"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"15507998","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ejiri, S."}],"nameIdentifiers":[{"nameIdentifier":"7798","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":"78_7_074507.pdf","filesize":[{"value":"971.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"78_7_074507.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2277/files/78_7_074507.pdf"},"version_id":"6ec80ab6-b179-4bc8-b329-0f8d29669940"}]},"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":"Canonical partition function and finite density phase transition in lattice QCD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Canonical partition function and finite density phase transition in lattice QCD"},{"subitem_title":"Canonical partition function and finite density phase transition in lattice QCD","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-23"},"publish_date":"2014-06-23","publish_status":"0","recid":"2277","relation_version_is_last":true,"title":["Canonical partition function and finite density phase transition in lattice QCD"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:11.372852+00:00"}
