The renormalization factor Z and the local moment 〈S2〉 are obtained as functions of the Coulomb interaction U, the exchange (Hund's rule) coupling J and the crystal-field splitting Δ. When the ionic ground state is triplet for Δ<Δc=3J, the heavy fermion state with the mass enhancement m*/m=Z-1≳100 together with 〈S2〉～2 is realized in the strong correlation regime for U≳W, where W is the conduction bandwidth. When the ionic ground state is singlet for Δ>Δc, m*/m～1 and 〈S2〉～0 for any value of U. When the singlet ground state and the triplet excited state form a quasi-quartet for Δ≳Δc, the system shows a moderate mass enhancement m*/m～10–100.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.physb.2006.01.224","subitem_relation_type_select":"DOI"}}]},"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":"AA10673546","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09214526","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ono, Y."}],"nameIdentifiers":[{"nameIdentifier":"62","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsumoto, K."}],"nameIdentifiers":[{"nameIdentifier":"7651","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":"1009.pdf","filesize":[{"value":"87.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1009.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2253/files/1009.pdf"},"version_id":"882e5fdc-091e-471b-ad6c-a1ef3f4cdba7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Filled skutterudite","subitem_subject_scheme":"Other"},{"subitem_subject":"Heavy fermion","subitem_subject_scheme":"Other"},{"subitem_subject":"Periodic Anderson model","subitem_subject_scheme":"Other"},{"subitem_subject":"Crystal-field splitting","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":"Heavy Fermions in the Periodic Anderson Model with Singlet-Triplet Crystal-Field Levels","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Heavy Fermions in the Periodic Anderson Model with Singlet-Triplet Crystal-Field Levels"},{"subitem_title":"Heavy Fermions in the Periodic Anderson Model with Singlet-Triplet Crystal-Field Levels","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-16"},"publish_date":"2014-04-16","publish_status":"0","recid":"2253","relation_version_is_last":true,"title":["Heavy Fermions in the Periodic Anderson Model with Singlet-Triplet Crystal-Field Levels"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:07.965579+00:00"}
