Here we develop time-dependent multicomponent density functional theory to study the coupled electron-positron dynamics from first principles. We prove that there are coupled time-dependent single-particle equations that can provide the electron and positron density dynamics, and derive the formally exact expression for their effective potentials. Introducing the adiabatic local density approximation to time-dependent electron-positron correlation, we apply the theory to the dynamics of a positronic lithium hydride molecule under a laser field. We demonstrate the significance of the coupling between electronic and positronic motion by revealing the complex positron detachment mechanism and the suppression of electronic resonant excitation by the screening effect of the positron.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The American Physical Society"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevLett.121.133001","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suzuki, Yasumitsu"}],"nameIdentifiers":[{"nameIdentifier":"499263","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hagiwara, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"499264","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Kazuyuki"}],"nameIdentifiers":[{"nameIdentifier":"499265","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"萩原 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"499266","nameIdentifierScheme":"WEKO"}]}]},"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":"Time-Dependent Multicomponent Density Functional Theory for Coupled Electron-Positron Dynamics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Time-Dependent Multicomponent Density Functional Theory for Coupled Electron-Positron Dynamics"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-09"},"publish_date":"2019-01-09","publish_status":"0","recid":"49431","relation_version_is_last":true,"title":["Time-Dependent Multicomponent Density Functional Theory for Coupled Electron-Positron Dynamics"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:48.026185+00:00"}
