Main results are the following :\n1) Large-scale Monte-Carlo simulations using very large paralell super computers were done in the lattice quantum chromodynamics (QCD). Hadron masses and matrix elements, heavy quark system, finite-temperature transition of QCD were studied. It is to be emphasized that Tsukuba group has clarified the features of finite-temperature transition of QCD with Wilson fermions.\n2) Monopole condensation and color confinement were studied using Monte-Carlo simulations of lattice SU (2) and SU (3) QCD.The role of monopoles and the relation between monopoles and instantons were clarified by Kanazawa and Hiroshima groups. New idea and technique using block-spin transformation on the dual lattice were proposed and almost renormalized trajectory is found in terms of monopoles.\nIn the last years, all the fund is devoted to organize Yukawa International Seminar on Non-perturbative QCD-Structure of the QCD vacuum- held at Institute of Theoretical physics at kyoto University from December 2 till December 12,1997.. Many members of the participants of this project were involved in the organizing commitee. The seminar is composed of 50 long talks and 38 short talks. In addition, three discussion hours were organized on color confinement and monopoles and instantons, renormalization transformation, hadron physics. The number of the total registered participants is 143.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:07304028, 研究期間(年度):1995–1997","subitem_description_type":"Other"},{"subitem_description":"出典：「格子上の場の理論」研究成果報告書　課題番号07304028\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00034862","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理学部"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60019502","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-07304028/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-07304028/073040281997kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"SC-PR-SUZUKI-T-kaken 1998-38p.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SUZUKI-T-kaken 1998-38p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34875/files/SC-PR-SUZUKI-T-kaken 1998-38p.pdf"},"version_id":"d2da7f7b-92ce-4ab2-8dc0-191fadd9729b"}]},"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":"格子上の場の理論","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"格子上の場の理論"},{"subitem_title":"Lattice field theories","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2836"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34875","relation_version_is_last":true,"title":["格子上の場の理論"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:50:24.986490+00:00"}
