It is found that the energy gap of the chain with length N scales as exp(-cN(omega)) with nonuniversal exponent omega if the Ising component of the exhange coupling is antiferromagnetic. This behavior is expected to be the characteristic feature of the quantum spin chains with relevant aperiodicity. This is in contrast to the XY chain for which the precious mean exchange modulation is marginal and the gap scales as N-z. On the contrary, it is also verified that the energy gap scales as N-1 if the Ising component of the exhange coupling is ferromagnetic. Our results are riot only consistent with the recent bosonization analysis of Vidal, Mouhanna and giamarchi(11)) but also clarify the nature of the strong coupling regime which is inaccesssible by the bosonization approach.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"PHYSICAL SOCIETY OF JAPAN"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00319015","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Hida, Kazuo"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002767"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科物質科学部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Physics, Faculty of Science, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2000-5"}]},"item_119_version_type_28":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飛田, 和男"},{"creatorName":"ヒダ, カズオ","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":"2018-01-24"}],"displaytype":"detail","filename":"A1002767.pdf","filesize":[{"value":"912.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002767.pdf","url":"https://sucra.repo.nii.ac.jp/record/13325/files/A1002767.pdf"},"version_id":"12742a68-089a-4102-bd1c-4692348c778e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"quasiperiodicity","subitem_subject_scheme":"Other"},{"subitem_subject":"XXZ chain","subitem_subject_scheme":"Other"},{"subitem_subject":"precious mean chain","subitem_subject_scheme":"Other"},{"subitem_subject":"density matrix renormalization group","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":"Density matrix renormalization group study of the S=1/2 anisotropic antiferromagnetic Heisenberg chains with quasiperiodic exchange modulation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Density matrix renormalization group study of the S=1/2 anisotropic antiferromagnetic Heisenberg chains with quasiperiodic exchange modulation"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-08-19"},"publish_date":"2008-08-19","publish_status":"0","recid":"13325","relation_version_is_last":true,"title":["Density matrix renormalization group study of the S=1/2 anisotropic antiferromagnetic Heisenberg chains with quasiperiodic exchange modulation"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:37:21.971783+00:00"}
