For a weak anharmonicity, it is confirmed that the first-order polaron\u2013bipolaron transition occurs from the observation of a discontinuity in the behavior of several physical quantities. When the anharmonicity is gradually increased, the polaron\u2013bipolaron transition temperature is reduced as well as the critical values of the electron\u2013phonon coupling constant for polaron\u2013bipolaron transition. For a strong anharmonicity, the polaron\u2013bipolaron transition eventually changes to a crossover behavior. The effect of anharmonicity on the formation of the heavy-electron state near the polaron\u2013bipolaron transition and the crossover region is discussed in detail.", "subitem_description_type": "Abstract"}]}, "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/JPSJ.81.044701", "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/JPSJ.81.044701", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2012 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": "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": "\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": "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\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-Electron Formation and Polaron-Bipolaron Transition in the Anharmonic Holstein Model", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "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": ["453/454", "176/488/489"], "permalink_uri": "http://hdl.handle.net/10191/26827", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "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}
