The transient coherent phonon spectra obtained at different time frames exhibit a Fano-like asymmetric line shape of the A21g mode, which is attributed to quantum interference between continuumlike coherent Dirac plasmons and phonons. By analyzing the time-dependent asymmetric line shape using the two-temperature model (TTM), it was determined that a Fano-like resonance persisted up to \u22481 ps after photo excitation with a relaxation profile dominated by Gaussian decay at \u2264200 fs. The asymmetry parameter could be well described by the TTM for \u2265200 fs, therefore suggesting the coherence time of the Dirac plasmon is \u2248200 fs.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society  "}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1103/PhysRevB.97.144306", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_9": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": " AA11187113  ", "subitem_relation_type_select": "NCID"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a92018 American Physical Society  "}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2469-9950", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Mondal, Richarj"}], "nameIdentifiers": [{"nameIdentifier": "191757", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Arai, Akira"}], "nameIdentifiers": [{"nameIdentifier": "191758", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Saito, Yuta"}], "nameIdentifiers": [{"nameIdentifier": "191759", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fons, Paul"}], "nameIdentifiers": [{"nameIdentifier": "191760", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kolobov, Alexander V."}], "nameIdentifiers": [{"nameIdentifier": "191761", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tominaga, Junji"}], "nameIdentifiers": [{"nameIdentifier": "191762", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hase, Muneaki"}], "nameIdentifiers": [{"nameIdentifier": "191763", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-06-11"}], "displaytype": "detail", "download_preview_message": "", "filename": "PRB_97_14-144306.pdf", "filesize": [{"value": "1.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 11000000, "url": {"label": "PRB_97_14-144306", "url": "https://tsukuba.repo.nii.ac.jp/record/46661/files/PRB_97_14-144306.pdf"}, "version_id": "329aad06-daa3-464f-bb1c-ded2775ee155"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Coherent Dirac plasmons in topological insulators", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Coherent Dirac plasmons in topological insulators"}]}, "item_type_id": "5", "owner": "1", "path": ["117/804", "3/62/5598/82"], "permalink_uri": "http://hdl.handle.net/2241/00151976", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2018-06-11"}, "publish_date": "2018-06-11", "publish_status": "0", "recid": "46661", "relation": {}, "relation_version_is_last": true, "title": ["Coherent Dirac plasmons in topological insulators"], "weko_shared_id": 5}
