In this process, the dynamics of the position vector is modeled by the Langevin equation with a linear restoring force and a fluctuating diffusivity (FD). This process can be interpreted as a simple model of relaxational dynamics with internal degrees of freedom or in a heterogeneous environment. By utilizing the functional integral expression and the transfer matrix method, we show that the relaxation function can be expressed in terms of the eigenvalues and eigenfunctions of the transfer matrix for general FD processes. We apply our general theory to two simple FD processes where the FD is described by the Markovian two-state model or an OU-type process. We show analytic expressions of the relaxation functions in these models and their asymptotic forms. We also show that the relaxation behavior of the OU process with an FD is qualitatively different from those obtained from conventional models such as the generalized Langevin equation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevE.99.032127","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2019 American Physical Society ","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_61":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"2470-0045","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uneyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"92670","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyaguchi, Tomoshige","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"92671","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akimoto, Takuma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"92672","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-11"}],"displaytype":"detail","filename":"PhysRevE99_032127.pdf","filesize":[{"value":"363.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevE99_032127","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/28353/files/PhysRevE99_032127.pdf"},"version_id":"b5ea80af-41ae-4a34-bb53-3f13a31d61bb"}]},"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":"Relaxation functions of the Ornstein-Uhlenbeck process with fluctuating diffusivity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relaxation functions of the Ornstein-Uhlenbeck process with fluctuating diffusivity","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-07-11"},"publish_date":"2019-07-11","publish_status":"0","recid":"28353","relation_version_is_last":true,"title":["Relaxation functions of the Ornstein-Uhlenbeck process with fluctuating diffusivity"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:20:59.223413+00:00"}
