(ii)\nWhile we have the massless Dirac dispersion only around E = 0, the anomalous\nQHE associated with the Dirac cone unexpectedly persists for a wide range of\nthe chemical potential. The range is bounded by van Hove singularities, at which\nwe predict a transition to the ordinary fermion behavior acompanied by huge\njumps in the QHE with a sign change. (iii) For edges we establish a coincidence\nbetween the quantum Hall effect in the bulk and the quantum Hall effect for the\nedge states, which is a manifestation of the topological bulk-edge correspondence.\nWe have also explicitly shown that the E = 0 edge states in honeycomb in zero\nmagnetic field persist in magnetic field.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/97689"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Berlin"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1140/epjst/e2007-00233-5","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2007 Springer"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1951-6355","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12197316","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hatsugai, Y."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukui, T."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoki, H."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-19"}],"displaytype":"detail","filename":"EPJ-ST_148-1.pdf","filesize":[{"value":"537.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"EPJ-ST_148-1.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/14894/files/EPJ-ST_148-1.pdf"},"version_id":"291cdbad-484e-4ace-b9e5-9adf61c180b6"}]},"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":"Topological aspects of graphene - Dirac fermions and the bulk-edge correspondence in magnetic fields","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Topological aspects of graphene - Dirac fermions and the bulk-edge correspondence in magnetic fields"}]},"item_type_id":"5","owner":"1","path":["483","445"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-12-11"},"publish_date":"2007-12-11","publish_status":"0","recid":"14894","relation_version_is_last":true,"title":["Topological aspects of graphene - Dirac fermions and the bulk-edge correspondence in magnetic fields"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:47:30.261776+00:00"}
