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": "\u51fa\u7248\u8005", "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": "\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": "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": "\u8457\u8005", "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": "\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": "1006.pdf", "filesize": [{"value": "166.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 166500.0, "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\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": "Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "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": ["453/454", "176/488/489"], "permalink_uri": "http://hdl.handle.net/10191/26877", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-04-16"}, "publish_date": "2014-04-16", "publish_status": "0", "recid": "2030", "relation": {}, "relation_version_is_last": true, "title": ["Nonadiabatic Interaction between Electrons and Jahn-Teller Distortions in a Silicon Vacancy"], "weko_shared_id": null}
