The two excitation modes can be observed by moving the barrier along different directions in appropriate parameter regimes. Phonon excitations are identified by the appearance of solitary waves, while roton excitations lead to distinctive spatial density modulations. We show that this method can also be used to determine the anisotropic critical velocities of superfluid.","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/PhysRevA.106.013302","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/pra/abstract/10.1103/PhysRevA.106.013302","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2022 American Physical Society"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2469-9926","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"2469-9934","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":"2022-08-04"}],"displaytype":"detail","filename":"Lyu-2022-Detection of roton and phonon excitat_vor.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","license_note":"CC BY 4.0\nCreative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Lyu-2022-Detection of roton and phonon excitat_vor","url":"https://oist.repo.nii.ac.jp/record/2737/files/Lyu-2022-Detection of roton and phonon excitat_vor.pdf"},"version_id":"dac019ba-2089-41f5-a8f5-560ab761b5c0"}]},"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":"Detection of roton and phonon excitations in a spin-orbit-coupled Bose-Einstein condensate with a moving barrier","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Detection of roton and phonon excitations in a spin-orbit-coupled Bose-Einstein condensate with a moving barrier","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"31","path":["13"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-08-04"},"publish_date":"2022-08-04","publish_status":"0","recid":"2737","relation_version_is_last":true,"title":["Detection of roton and phonon excitations in a spin-orbit-coupled Bose-Einstein condensate with a moving barrier"],"weko_creator_id":"31","weko_shared_id":31},"updated":"2023-06-26T11:25:20.720446+00:00"}
