We verify the theory by experimentally probing the [Formula: see text] transition rate in ⁸⁷Rb in two configurations: paraxial light excitation of warm vapor and nonparaxial excitation of laser-cooled atoms. The transition rate follows a quadratic dependence on the helicity parameter linked to the excitation light's polarization. For paraxial excitation, the transition rate scales as the squared degree of linear polarization, being zero for circularly polarized light. In contrast, for nonparaxial excitation via an optical nanofiber, the two-photon transition is not completely extinguished by varying the light polarization. Our findings lead to a deeper and more universal understanding of the physics of multiphoton processes in atoms.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevResearch.2.033341","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.2.033341","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 American Physical Society"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2643-1564","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-18"}],"displaytype":"detail","filename":"Rajasree-2020-Spin selection in single-frequen.pdf","filesize":[{"value":"502.0 kB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Rajasree-2020-Spin selection in single-frequen","url":"https://oist.repo.nii.ac.jp/record/1802/files/Rajasree-2020-Spin selection in single-frequen.pdf"},"version_id":"90f3a138-6ad0-42e1-b322-0db2399a4e98"}]},"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":"Spin selection in single-frequency two-photon excitation of alkali-metal atoms","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spin selection in single-frequency two-photon excitation of alkali-metal atoms","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["13","47"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-18"},"publish_date":"2020-11-18","publish_status":"0","recid":"1802","relation_version_is_last":true,"title":["Spin selection in single-frequency two-photon excitation of alkali-metal atoms"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:42:38.333868+00:00"}
