The model is solved by using the dynamical mean-field theory in conjunction with the exact diagonalization method. It is found that the heavy fermion state is realized due to the effect of cooperation between the Coulomb interaction and the electron–phonon coupling. Remarkably, the enhancement of lattice fluctuation and the phonon softening observed in the strong coupling regime are largely enhanced due to the Coulomb interaction in contrast to the case with the single-orbital Anderson lattice model.", "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.2007.10.047", "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": "Mitsumoto, K."}], "nameIdentifiers": [{"nameIdentifier": "7646", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ono, Y."}], "nameIdentifiers": [{"nameIdentifier": "62", "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": "999.pdf", "filesize": [{"value": "157.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 157300.0, "url": {"label": "999.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2251/files/999.pdf"}, "version_id": "abf322dc-1187-4380-9dce-38770c176816"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Two-orbital Anderson lattice model", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Coulomb interaction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Electron–phonon coupling", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Heavy fermion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamical mean-field theory", "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": "Dynamical mean-field study of the heavy-fermion state in the multi-orbital Anderson lattice model coupled with Jahn-Teller phonons", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Dynamical mean-field study of the heavy-fermion state in the multi-orbital Anderson lattice model coupled with Jahn-Teller phonons"}, {"subitem_title": "Dynamical mean-field study of the heavy-fermion state in the multi-orbital Anderson lattice model coupled with Jahn-Teller phonons", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/26906", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-04-16"}, "publish_date": "2014-04-16", "publish_status": "0", "recid": "2251", "relation": {}, "relation_version_is_last": true, "title": ["Dynamical mean-field study of the heavy-fermion state in the multi-orbital Anderson lattice model coupled with Jahn-Teller phonons"], "weko_shared_id": null}
