The usual equilibrium simulation predicts the occurrence of a floating incommensurate (IC) Kosterlitz-Thouless (KT) type phase, which never emerges in non-equilibrium relaxation (NER) simulations. In this paper, we first examine previously published results of both methods, and then investigate a higher transition temperature Tc1 between the IC and paramagnetic phases. In the usual equilibrium simulation, we calculate the chain magnetization on larger lattices (up to 512×512 sites) and estimate Tc1≈1.16J with frustration ratio κ(≡−J2/J1)=0.6. We examine the nature of the phase transition in terms of the Binder ratio gL of spin overlap functions and the correlation-length ratio ξ/L. In the NER simulation, we observe the spin dynamics in equilibrium states by means of an autocorrelation function and also observe the chain magnetization relaxations from the ground and disordered states. These quantities exhibit an algebraic decay at T≲1.17J. We conclude that the two-dimensional ANNNI model actually admits an IC phase transition of the KT type.","subitem_description_type":"Other"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.90.144410","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2014 American Physical Society"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Faculty of Humanities and Social Sciences, Iwate University"},{"subitem_text_value":"Department of Applied Physics, Tohoku University"},{"subitem_text_value":"Faculty of Science and Technology, Tohoku Bunka Gakuen University"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shirakura, T"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsubara, F"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, N"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"prb-v90p144410.pdf","filesize":[{"value":"848.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"prb-v90p144410.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/14045/files/prb-v90p144410.pdf"},"version_id":"04d515f1-1e60-4787-bfd1-be9b54c2727a"}]},"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":"Kosterlitz-Thouless phase transition of the axial next-nearest-neighbor Ising model in two dimensions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Kosterlitz-Thouless phase transition of the axial next-nearest-neighbor Ising model in two dimensions"}]},"item_type_id":"16","owner":"3","path":["1800"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-02-06"},"publish_date":"2015-02-06","publish_status":"0","recid":"14045","relation_version_is_last":true,"title":["Kosterlitz-Thouless phase transition of the axial next-nearest-neighbor Ising model in two dimensions"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:09:44.120193+00:00"}
