In the case of strong quantum fluctuations, we clarified a phenomenon called quasi many-body localization exhibited by polar gases with long-range interactions in an optical lattice. In the case of weak quantum fluctuations, we studied the motion of dark solitons in Bose-Einstein condensates in an optical lattice, showing that there is the classical-quantum crossover. In the two-component Bose gas in an optical lattice, we showed that the quantum droplet can be induced by strong quantum fluctuations.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C); 研究期間：2018～2021; 課題番号：18K03472; 研究分野：物性理論; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kasamatsu, Kenichi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"笠松, 健一"},{"creatorName":"カサマツ, ケンイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3263","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70413763","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=70413763"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"18K03472seika.pdf","filesize":[{"value":"707.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18K03472seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23364/files/18K03472seika.pdf"},"version_id":"54899bad-288e-4b9d-8f74-6d1bce22ab03"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"冷却原子","subitem_subject_scheme":"Other"},{"subitem_subject":"ボースアインシュタイン凝縮","subitem_subject_scheme":"Other"},{"subitem_subject":"光格子","subitem_subject_scheme":"Other"},{"subitem_subject":"長距離相互作用","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"光格子中の長距離相互作用を有する冷却原子系における非平衡量子ダイナミクスの解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"光格子中の長距離相互作用を有する冷却原子系における非平衡量子ダイナミクスの解明","subitem_title_language":"ja"},{"subitem_title":"Nonequilibrium dynamics of cold atoms with long-range interaction in optical lattices","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23364","relation_version_is_last":true,"title":["光格子中の長距離相互作用を有する冷却原子系における非平衡量子ダイナミクスの解明"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-12T05:04:37.045755+00:00"}
