To achieve deep understanding on these issues, we perform a functional renormalization group (fRG) study for the two-orbital Hubbard model. The vertex corrections for the electron-boson coupling (U-VC), which are dropped in the Migdal-Eliashberg gap equation, are obtained by solving the RG equation. We reveal that the dressed electron-boson coupling for the charge channel Uˆceff becomes much larger than the bare Coulomb interaction Uˆ0 due to the U-VC in the presence of moderate spin fluctuations. For this reason, the attractive pairing interaction due to the charge or orbital fluctuations is enlarged by the factor (Uˆceff/Uˆ0)2\u003e\u003e1. In contrast, the spin fluctuation pairing interaction is suppressed by the spin-channel U-VC, because of the relation Uˆseff\u003c\u003cUˆ0. The present study demonstrates that the orbital or charge fluctuation pairing mechanism can be realized in various multiorbital systems thanks to the U-VC, such as in Fe-based superconductors.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1103/PhysRevB.94.115155"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/25206"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1103/PhysRevB.94.115155", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2016 American Physical Society", "subitem_rights_language": "en"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2469-9950", "subitem_source_identifier_type": "PISSN"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tazai, Rina", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "68040", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamakawa, Youichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "68041", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tsuchiizu, Masahisa", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "68042", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kontani, Hiroshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "68043", "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": "2018-02-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevB_94_115155.pdf", "filesize": [{"value": "915.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 915800.0, "url": {"label": "PhysRevB_94_115155.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/23020/files/PhysRevB_94_115155.pdf"}, "version_id": "a0bfee17-40d2-44ca-bbcf-62b31561c957"}]}, "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": "Functional renormalization group study of orbital fluctuation mediated superconductivity: Impact of the electron-boson coupling vertex corrections", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Functional renormalization group study of orbital fluctuation mediated superconductivity: Impact of the electron-boson coupling vertex corrections", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["696"], "permalink_uri": "http://hdl.handle.net/2237/25206", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2016-12-15"}, "publish_date": "2016-12-15", "publish_status": "0", "recid": "23020", "relation": {}, "relation_version_is_last": true, "title": ["Functional renormalization group study of orbital fluctuation mediated superconductivity: Impact of the electron-boson coupling vertex corrections"], "weko_shared_id": -1}
