The dependence of the MQT rate on the twist angle \u03b3 about the c axis is calculated by using the functional integral and the bounce method. Due to the d-wave OPS, the \u03b3 dependence of standard deviation of the switching current distribution and the crossover temperature\nfrom thermal activation to MQT are found to be given by cos  2\u03b3 and sqrt(cos 2 \u03b3 ), 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+\u03b4 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_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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevB.76.134501", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "American Physical Society, All rights reserved."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yokoyama, Takehito"}], "nameIdentifiers": [{"nameIdentifier": "27070", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawabata, Shiro"}], "nameIdentifiers": [{"nameIdentifier": "27071", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kato, Takeo"}], "nameIdentifiers": [{"nameIdentifier": "27072", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Yukio"}], "nameIdentifiers": [{"nameIdentifier": "27073", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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_free", "mimetype": "application/pdf", "size": 411600.0, "url": {"label": "PhysRevB_76_134501.pdf", "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Theory of macroscopic quantum tunneling in high-T_c c-axis Josephson junctions"}]}, "item_type_id": "10", "owner": "1", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/11286", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "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": 3}
