The dependence of the MQT rate on the twist angle γ about the c axis is calculated by using the functional integral and the bounce method. Due to the d-wave OPS, the γ dependence of standard deviation of the switching current distribution and the crossover temperaturefrom thermal activation to MQT are found to be given by cos  2γ and sqrt(cos 2 γ ), respectively. We also show that a dissipative effect resulting from the nodal quasiparticle excitation on MQT is negligibly small, which is consistent with recent MQT experiments using Bi_2Sr_2CaCu_2O_8+δ intrinsic junctions. These results indicate that MQT in c-axis twist junctions becomes a useful experimental tool for testing the OPS of high-T_c materials at low temperature, and suggest high potential of such junctions for qubit applications.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/11286"}]},"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/PhysRevB.76.134501","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"American Physical Society, All rights reserved.","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yokoyama, Takehito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27070","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawabata, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27071","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kato, Takeo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27072","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Yukio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27073","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":"2018-02-20"}],"displaytype":"detail","filename":"PhysRevB_76_134501.pdf","filesize":[{"value":"411.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevB_76_134501.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/9504/files/PhysRevB_76_134501.pdf"},"version_id":"b793d1ad-cef2-4668-8678-763cc43896ab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"high-temperature superconductors","subitem_subject_scheme":"Other"},{"subitem_subject":"Josephson effect","subitem_subject_scheme":"Other"},{"subitem_subject":"quantum theory","subitem_subject_scheme":"Other"}]},"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":"Theory of macroscopic quantum tunneling in high-T_c c-axis Josephson junctions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Theory of macroscopic quantum tunneling in high-T_c c-axis Josephson junctions","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-10"},"publish_date":"2009-03-10","publish_status":"0","recid":"9504","relation_version_is_last":true,"title":["Theory of macroscopic quantum tunneling in high-T_c c-axis Josephson junctions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:55:09.255864+00:00"}
