In the semimetallic case, the difference in the band degeneracy inevitably causes the imbalance of each Fermi wavenumber, resulting in a remarkable excitonic state characterized by the condensation of excitons with finite center-of-mass momentum q, the so-called Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) excitonic state. With decreasing D corresponding to increasing pressure, the obtained excitonic phase diagram shows a crossover from BEC (D >__～ 0) to BCS (D <__～ 0) regime, and then shows a distinct phase transition at a certain critical value D_c(< 0) from the uniform (q = 0) to the FFLO (q ≠ 0) excitonic state, as expected to be observed in Ta_2NiSe_5 under high pressure.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Physical Society of Japan"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.7566/JPSJ.85.053703","subitem_relation_type_select":"DOI"}}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://journals.jps.jp/doi/abs/10.7566/JPSJ.85.053703","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2016 The Physical Society of Japan"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00704814","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00319015","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamada, Takemi"}],"nameIdentifiers":[{"nameIdentifier":"7084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Domon, Kaoru"}],"nameIdentifiers":[{"nameIdentifier":"7085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"62","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":"2019-07-29"}],"displaytype":"detail","filename":"85_053703.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"85_053703.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2110/files/85_053703.pdf"},"version_id":"6f35aca7-38d1-496a-8ecf-bc0b2e2eacfc"}]},"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":"FFLO Excitonic State in the Three-Chain Hubbard Model for Ta_2NiSe_5","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FFLO Excitonic State in the Three-Chain Hubbard Model for Ta_2NiSe_5"},{"subitem_title":"FFLO Excitonic State in the Three-Chain Hubbard Model for Ta_2NiSe_5","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-18"},"publish_date":"2017-07-18","publish_status":"0","recid":"2110","relation_version_is_last":true,"title":["FFLO Excitonic State in the Three-Chain Hubbard Model for Ta_2NiSe_5"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:33:20.215191+00:00"}
