For the strong electron-phonon coupling g≳gc, the system shows an anomalous heavy-fermion behaviour which is accompanied by a large lattice fluctuation and an extreme phonon softening. We also calculate an effective potential for the ions and find that a simple harmonic potential for g≲gc changes into a double-well potential for g≳gc. The effective pairing interaction between the conduction electrons shows a maximum at g≈gc where the superconducting transition temperature is expected to be maximum.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"62","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大野, 義章"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.physc.2004.12.021","subitem_relation_type_select":"DOI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Elsevier B.V."}]},"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":"AA11461984","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09214534","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mitsumoto, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"7643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yoshiaki"}],"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","filename":"19_0004.pdf","filesize":[{"value":"204.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19_0004.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2250/files/19_0004.pdf"},"version_id":"b0ffe8c4-04e1-4a14-9098-f0b5615bd2ce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Electron-phonon interaction","subitem_subject_scheme":"Other"},{"subitem_subject":"Heavy-fermion","subitem_subject_scheme":"Other"},{"subitem_subject":"Superconductivity","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":"Phonon softening and double-well potential formation due to electron-phone interaction in heavy-fermion systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phonon softening and double-well potential formation due to electron-phone interaction in heavy-fermion systems"},{"subitem_title":"Phonon softening and double-well potential formation due to electron-phone interaction in heavy-fermion systems","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-23"},"publish_date":"2007-04-23","publish_status":"0","recid":"2250","relation_version_is_last":true,"title":["Phonon softening and double-well potential formation due to electron-phone interaction in heavy-fermion systems"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:07.745452+00:00"}
