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", "download_preview_message": "", "file_order": 0, "filename": "PhysRevB_76_134501.pdf", "filesize": [{"value": "411.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 411600.0, "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"], "permalink_uri": "http://hdl.handle.net/2237/11286", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-03-10"}, "publish_date": "2009-03-10", "publish_status": "0", "recid": "9504", "relation": {}, "relation_version_is_last": true, "title": ["Theory of macroscopic quantum tunneling in high-T_c c-axis Josephson junctions"], "weko_shared_id": -1}
