The reason has been widely believed to be the irreversibility in nature, while an obvious demonstration for this belief has not been accomplished yet. In order to resolve the question from a microscopic viewpoint, an implosion process dual to an explosion process was investigated by means of the molecular-dynamics method (MD). To this aim, we employed a \"bit-reversible algorithm (Bit MD)\" that was completely time-reversible in a microscopic viewpoint and was free from any round-off error. Here we show that, through a dual implosion simulation (i.e., a time-reversible simulation of the explosion), a kind of expansion shock wave is successfully formed in the Bit MD simulation. Furthermore, we show that when the controlled noise is intentionally added to the Bit MD, the expansion shock wave disappears dramatically and turns into an isentropic expansion wave, even if the noise is extremely small. Since the controlled noise gives rise to the irreversibility in the Bit MD simulation, it can be concluded that the irreversibility in the system prohibits the expansion shock wave from appearing in the system. © 2007 American Institute of Physics.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科機能開発システム","subitem_description_type":"Other"},{"subitem_description":"金沢大学工学部","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1063/1.2717725","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1070-6631","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"Komatsu, Nobuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"459","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20436827","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20436827"},{"nameIdentifier":"20436827","nameIdentifierScheme":"金沢大学研究者情報","nameIdentifierURI":"http://ridb.kanazawa-u.ac.jp/public/detail.php?kaken=20436827"},{"nameIdentifier":"20436827","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000020436827"}]},{"creatorNames":[{"creatorName":"Abe, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"10384","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":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-KOMATSU-N-056103.pdf","filesize":[{"value":"413.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-KOMATSU-N-056103.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/7695/files/TE-PR-KOMATSU-N-056103.pdf"},"version_id":"a1ed9fed-5621-429f-a7a4-a1a28fa5bd6f"}]},"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":"Expansion shock waves in the implosion process from a time-reversible molecular-dynamics simulation of a dual explosion process","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Expansion shock waves in the implosion process from a time-reversible molecular-dynamics simulation of a dual explosion process"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"7695","relation_version_is_last":true,"title":["Expansion shock waves in the implosion process from a time-reversible molecular-dynamics simulation of a dual explosion process"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-06-20T06:25:41.482320+00:00"}
