It is found that the heavy fermion state caused by U is largely enhanced due to the effect of g . In the heavy fermion state for large U and g , both the orbital and lattice fluctuations are enhanced, while the charge (valence) and spin fluctuations are suppressed; this is a nonmagnetic origin of the heavy fermions. The effect of the mass enhancement for the case with twofold-degenerate phonon mode is larger than that for one phonon mode. The obtained results show a possible nonmagnetic origin of the heavy fermion state recently observed in SmOs4Sb12.", "subitem_description_type": "Abstract"}]}, "item_5_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "Proceedings of the International Conference on Heavy Electrons 2010 (ICHE2010)", "subitem_description_type": "Other"}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u7269\u7406\u5b66\u4f1a"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1143/JPSJS.80SA.SA138", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://journals.jps.jp/doi/abs/10.1143/JPSJS.80SA.SA138", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2011 The Physical Society of Japan"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00704814", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00319015", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Mitsumoto, Keisuke"}], "nameIdentifiers": [{"nameIdentifier": "7112", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ono, Yoshiaki"}], "nameIdentifiers": [{"nameIdentifier": "62", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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": "977.pdf", "filesize": [{"value": "83.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 83400.0, "url": {"label": "977.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2120/files/977.pdf"}, "version_id": "e1ef3f43-d3b8-4a91-b67a-39668b03e520"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "heavy fermion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "periodic Anderson model", "subitem_subject_scheme": "Other"}, {"subitem_subject": "orbital degeneracy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Coulomb interaction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electron\u2013phonon coupling", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Jahn\u2013Teller phonon", "subitem_subject_scheme": "Other"}, {"subitem_subject": "dynamical mean-field theory", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Heavy Fermions due to Cooperative Effects of Coulomb and Electron-Phonon Interactions in the Two-Orbital Periodic Anderson Model", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Heavy Fermions due to Cooperative Effects of Coulomb and Electron-Phonon Interactions in the Two-Orbital Periodic Anderson Model"}, {"subitem_title": "Heavy Fermions due to Cooperative Effects of Coulomb and Electron-Phonon Interactions in the Two-Orbital Periodic Anderson Model", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "176/488/489"], "permalink_uri": "http://hdl.handle.net/10191/26829", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-04-15"}, "publish_date": "2014-04-15", "publish_status": "0", "recid": "2120", "relation": {}, "relation_version_is_last": true, "title": ["Heavy Fermions due to Cooperative Effects of Coulomb and Electron-Phonon Interactions in the Two-Orbital Periodic Anderson Model"], "weko_shared_id": null}
