Contrary to this belief, we recently have found the 6-fold bronze-mean tiling. In this project, by generalizing the Ammann-Beenker tiling and the bronze-mean tiling, we show an infinite number of 4-fold and 6-fold aperiodic tilings with various inflation factors including even metallic means and the metallic-mean of multiples of three. Implying that we cover two-thirds of metallic means (k=3, 4, 6, 8, 9, 10, 12, ...) as the inflation factors of new quasicrystals by using conventional square and hexagonal rotational symmetries. In the limit of these tilings, they become the square lattice or the hexagonal lattice; they are thus considered as quasiperiodic approximants to periodic crystals, and fill the gap between quasicrystals and incommensurate structures.","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：2019～2021; 課題番号：19K03777; 研究分野：物性物理学; 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"},{"subitem_text_value":"研究協力者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Dotera, Tomonari"},{"subitem_text_language":"en","subitem_text_value":"Matsuzawa, Junichi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"},{"subitem_text_value":"奈良女子大学理学部; 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":"堂寺, 知成"},{"creatorName":"ドウテラ, トモナリ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"松澤, 淳一"},{"creatorName":"マツザワ, ジュンイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"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":"19K03777seika.pdf","filesize":[{"value":"377.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19K03777seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23375/files/19K03777seika.pdf"},"version_id":"5e739d71-f07c-45f5-9fdd-7b8c1dc44790"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"準結晶","subitem_subject_scheme":"Other"},{"subitem_subject":"ソフトマター","subitem_subject_scheme":"Other"},{"subitem_subject":"結晶学","subitem_subject_scheme":"Other"},{"subitem_subject":"分子シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"タイリング","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":"ソフトマター準結晶と準周期タイリング理論の革新的展開","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ソフトマター準結晶と準周期タイリング理論の革新的展開","subitem_title_language":"ja"},{"subitem_title":"Advanced study of softmatter quasicrystals and quasiperiodic tiling theory","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":"23375","relation_version_is_last":true,"title":["ソフトマター準結晶と準周期タイリング理論の革新的展開"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-12T05:45:20.087212+00:00"}
