For a weak anharmonicity, it is confirmed that the first-order polaron–bipolaron transition occurs from the observation of a discontinuity in the behavior of several physical quantities. When the anharmonicity is gradually increased, the polaron–bipolaron transition temperature is reduced as well as the critical values of the electron–phonon coupling constant for polaron–bipolaron transition. For a strong anharmonicity, the polaron–bipolaron transition eventually changes to a crossover behavior. The effect of anharmonicity on the formation of the heavy-electron state near the polaron–bipolaron transition and the crossover region is discussed in detail.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本物理学会"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1143/JPSJ.81.044701", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://journals.jps.jp/doi/abs/10.1143/JPSJ.81.044701", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2012 The Physical Society of Japan"}]}, "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": "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": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Fuse, Takahiro"}], "nameIdentifiers": [{"nameIdentifier": "7105", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ono, Yoshiaki"}], "nameIdentifiers": [{"nameIdentifier": "62", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hotta, Takashi"}], "nameIdentifiers": [{"nameIdentifier": "7107", "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": "974.pdf", "filesize": [{"value": "679.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 679900.0, "url": {"label": "974.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2117/files/974.pdf"}, "version_id": "55673687-9803-47e8-8ddb-768cda6448d5"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "heavy electron", "subitem_subject_scheme": "Other"}, {"subitem_subject": "anharmonicity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "rattling", "subitem_subject_scheme": "Other"}, {"subitem_subject": "bipolaron", "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": "Heavy-Electron Formation and Polaron-Bipolaron Transition in the Anharmonic Holstein Model", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Heavy-Electron Formation and Polaron-Bipolaron Transition in the Anharmonic Holstein Model"}, {"subitem_title": "Heavy-Electron Formation and Polaron-Bipolaron Transition in the Anharmonic Holstein Model", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/26827", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-04-15"}, "publish_date": "2014-04-15", "publish_status": "0", "recid": "2117", "relation": {}, "relation_version_is_last": true, "title": ["Heavy-Electron Formation and Polaron-Bipolaron Transition in the Anharmonic Holstein Model"], "weko_shared_id": null}
