The renormalization factor Z and the local moment 〈S2〉 are obtained as functions of the Coulomb interaction U, the exchange (Hund\u0027s rule) coupling J and the crystal-field splitting Δ. When the ionic ground state is triplet for Δ\u003cΔc=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\u003eΔc, 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", "download_preview_message": "", "file_order": 0, "filename": "1009.pdf", "filesize": [{"value": "87.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 87800.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/26908", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-04-16"}, "publish_date": "2014-04-16", "publish_status": "0", "recid": "2253", "relation": {}, "relation_version_is_last": true, "title": ["Heavy Fermions in the Periodic Anderson Model with Singlet-Triplet Crystal-Field Levels"], "weko_shared_id": null}
