The tight transverse confinement of guided light over an extended length (> 1000!) offers strong atom-light interactions with potential long-range atom-atom interactions mediated by the guided light, allowing for better scalability in many quantum information applications than their corresponding free-space implementations. We demonstrated, experimentally, an electric quadrupole transition and a single-frequency two-photon transition in cold 87Rb atoms driven by nanofiber-guided light, establishing ONFs as excellent platforms for potential applications in compact fiber-based clocks and correlated photon pair sources. ONFs are well-suited for nonlinear collective interactions, such as four-wave mixing and superradiance, that require an ensemble of phase-matched quantum emitters coupled to a common radiation field. An effective system is a 1D array of few hundred atoms trapped near an ONF surface and coupled with the guided mode. A crucial requirement is maximizing the number of trapped atoms which remains challenging in the absence of a quantitative description of atom dynamics during the trap-loading process involving many-body interactions and complex scattering process. We experimentally optimized, leveraging the ability of machine learning algorithms, the number of 87Rb atoms loaded in a shallow fiber-based dipole trap by parametrizing the control of magneto-optical trap parameters. This sets the first step toward planned studies on optical nanofiber mediated collective atom-light interactions and nearest-neighbor interactions in a 1D lattice of Rydberg atoms.","subitem_description_type":"Other"}]},"item_10006_dissertation_number_12":{"attribute_name":"Degree Referral Number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第94号"}]},"item_10006_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15102/1394.00002391","subitem_identifier_reg_type":"JaLC"}]},"item_10006_rights_13":{"attribute_name":"Copyright Information","attribute_value_mlt":[{"subitem_rights":"© 2022 The Author."}]},"item_10006_text_24":{"attribute_name":"Exam Date","attribute_value_mlt":[{"subitem_text_value":"2022-04-26"}]},"item_10006_version_type_18":{"attribute_name":"Version Format","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"displaytype":"detail","filename":"Gupta-FullText.pdf","filesize":[{"value":"25.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Gupta-FullText","objectType":"fulltext","url":"https://oist.repo.nii.ac.jp/record/2653/files/Gupta-FullText.pdf"},"version_id":"ec45cb36-bd7f-4150-8488-89a64ed3b172"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-09"}],"displaytype":"detail","filename":"Gupta-FinalExamAbstract.pdf","filesize":[{"value":"42.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Gupta-FinalExamAbstract","objectType":"abstract","url":"https://oist.repo.nii.ac.jp/record/2653/files/Gupta-FinalExamAbstract.pdf"},"version_id":"3de09ff6-23da-4b0c-8705-b8220f79bd79"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"冷たいルビジウム原子と光ナノファイバーモードとのエバネッセント場媒介相互作用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"冷たいルビジウム原子と光ナノファイバーモードとのエバネッセント場媒介相互作用","subitem_title_language":"ja"},{"subitem_title":"Evanescent Field Mediated Interactions of Cold Rubidium Atoms with Optical Nanofiber Guided Light","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"22","path":["235"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-09"},"publish_date":"2022-06-09","publish_status":"0","recid":"2653","relation_version_is_last":true,"title":["冷たいルビジウム原子と光ナノファイバーモードとのエバネッセント場媒介相互作用"],"weko_creator_id":"22","weko_shared_id":-1},"updated":"2023-09-01T02:32:58.632558+00:00"}
