The three-quarter Dirac point is realized in the system of massless Dirac fermions with the critically tilted Dirac cone in one direction, where a linear term disappears and a quadratic term α2q2x with a constant α2 plays an important role. The energy is obtained as En∝α352(nB)45, where n=1,2,3,⋯, by means of numerically solving the differential equation. The same result is obtained analytically by adopting an approximation. The result is consistent with the semiclassical quantization rule studied previously. The existence of the n=0 state is studied by introducing the energy gap due to the inversion-symmetry-breaking term, and it is obtained that the n=0 state exists in one of a pair of three-quarter Dirac points, depending on the direction of the magnetic field when the energy gap is finite.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.99.045409","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_16_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.99.045409","subitem_relation_type_select":"DOI"}}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2019 American Physical Society"}]},"item_16_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24699950","subitem_source_identifier_type":"ISSN"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"428","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"4390161 bytes"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"長谷川, 泰正","creatorNameLang":"en"},{"creatorName":"ハセガワ, ヤスマサ","creatorNameLang":"ja-Kana"},{"creatorName":"Hasegawa, Yasumasa","creatorNameLang":"en"}],"familyNames":[{"familyName":"長谷川","familyNameLang":"en"},{"familyName":"ハセガワ","familyNameLang":"ja-Kana"},{"familyName":"Hasegawa","familyNameLang":"en"}],"givenNames":[{"givenName":"泰正","givenNameLang":"en"},{"givenName":"ヤスマサ","givenNameLang":"ja-Kana"},{"givenName":"Yasumasa","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"147886","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishigi, Keita"}],"nameIdentifiers":[{"nameIdentifier":"147885","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-03"}],"displaytype":"detail","filename":"PhysRevB.99.045409.pdf","filesize":[{"value":"4.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevB.99.045409.pdf","url":"https://kumadai.repo.nii.ac.jp/record/31013/files/PhysRevB.99.045409.pdf"},"version_id":"e58e5865-1ca1-484c-a651-8aff5c2c7245"}]},"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":"Energy quantization at the three-quarter Dirac point in a magnetic field","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Energy quantization at the three-quarter Dirac point in a magnetic field"}]},"item_type_id":"16","owner":"1","path":["444"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-31"},"publish_date":"2019-01-31","publish_status":"0","recid":"31013","relation_version_is_last":true,"title":["Energy quantization at the three-quarter Dirac point in a magnetic field"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-09-13T08:17:35.078806+00:00"}
