To investigate the quantum state of the silicon vacancy, we introduce a cluster model which includes the electron-lattice coupling between electrons and Jahn-Teller distortions together with the Coulomb interaction between electrons. By using the numerical diagonalization method, we take into account of both the nonadiabatic and the correlation e ects. We  nd that the 3-fold orbital degeneracy in the ground state of a silicon vacancy is stable against the Jahn-Teller distortions because of the strong quantum fluctuation due to the nonadiabatic coupling between electrons and Jahn-Teller distortions. The obtained result is a striking contrast to the previous theoretical results within the adiabatic approximation and is consistent with the newly observed experiment.","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.jmmm.2006.10.414","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":"AA00701394","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03048853","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamakawa, Y."}],"nameIdentifiers":[{"nameIdentifier":"6699","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsumoto, K."}],"nameIdentifiers":[{"nameIdentifier":"6700","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","filename":"1006.pdf","filesize":[{"value":"166.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1006.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2030/files/1006.pdf"},"version_id":"5963a64c-088d-4891-8239-3a32c9cbac3d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"silicon vacancy","subitem_subject_scheme":"Other"},{"subitem_subject":"Jahn-Teller effect","subitem_subject_scheme":"Other"},{"subitem_subject":"electron-phonon coupling","subitem_subject_scheme":"Other"},{"subitem_subject":"nonadiabatic effect","subitem_subject_scheme":"Other"},{"subitem_subject":"electron correlation","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":"Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy"},{"subitem_title":"Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-16"},"publish_date":"2014-04-16","publish_status":"0","recid":"2030","relation_version_is_last":true,"title":["Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:49.980653+00:00"}
