Firstly, we examine the spectral shape of the optical conductivity by using time-dependent density-matrix renormalization group implemented by the Legendre polynomial expansion. We find a shape peak resembling to an excitonic peak at absorption edge, whose origin is attributable to antiferromagnetic\ncorrelation in the spin background. We next investigate momentum-dependent transient charge and spin dynamics after photoirradiation by using time-dependent Lanczos-type exact diagonalization. We find a temporal oscillation in the intensity of the dynamical spin structure factor, which exhibits an antiphase behavior between, for example, two orthogonal momentum\ndirections parallel and perpendicular to the electric field of a pump pulse. Observing such antiphase oscillations will be a big challenge for time-resolved resonant-inelastic x-ray scattering experiments.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1742-6596/2207/1/012028","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1742-6596/2207/1/012028","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1742-6596","subitem_source_identifier_type":"ISSN"}]},"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":"Tohyama, Takami"}],"nameIdentifiers":[{"nameIdentifier":"1047579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinjo, Kazuya"}],"nameIdentifiers":[{"nameIdentifier":"1047580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sota, Shigetoshi"}],"nameIdentifiers":[{"nameIdentifier":"1047581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsutsui, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"1047582","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kenji, Tsutsui","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1047583","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":"Numerical simulations of spectroscopic properties in two-dimensional Mott insulator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical simulations of spectroscopic properties in two-dimensional Mott insulator"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-09-01"},"publish_date":"2021-09-01","publish_status":"0","recid":"85808","relation_version_is_last":true,"title":["Numerical simulations of spectroscopic properties in two-dimensional Mott insulator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:12:24.642258+00:00"}
