The partition function in a Feynman path-integral form is sampled over a semiclassical reference system of 128 MC particles, with quantum fluctuations generated according to the Wigner-Seitz model. Exchange effects are shown to be negligible. Helmholtz-free  energies of the Coulomb solid, computed at 48 combinations of density and temperature parameters, are decomposed into harmonic and anharmonic contributions and are fitted to analytic formulas; accuracy of the result is confirmed through comparison with the Wigner-Kirkwood expansions and with the ground-state results. The free-energy formulas are applied for calculation of the melting curves in dense carbon and helium OCP materials, appropriate to interiors of degenerate stars, showing that the melting curves start to deviate from the classical predictions at around ρm=2×108 g/cm3 (C) and 2×103 g/cm3 (He), far lower than the values predicted by analyses of the Lindemann type.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"尾形, 修司"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_10001_relation_34":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1103/PhysRevB.47.11703"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevB.47.11703","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01631829","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AA00362255","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Iyetomi, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogata, Shuji","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Ichimaru, Setsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-23"}],"displaytype":"detail","filename":"PRB 47_11703.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","license_note":"(c)1993 The American Physical Society","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/4214/files/PRB 47_11703.pdf"},"version_id":"18ad1669-2af1-4563-9db2-b2cea383e27d"}]},"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":"Quantum Monte Carlo simulation study of free energies and melting transitions in Coulomb solids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Quantum Monte Carlo simulation study of free energies and melting transitions in Coulomb solids","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-11-07"},"publish_date":"2012-11-07","publish_status":"0","recid":"4214","relation_version_is_last":true,"title":["Quantum Monte Carlo simulation study of free energies and melting transitions in Coulomb solids"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-16T14:23:32.245456+00:00"}
