The conventional quantum many-body scarred model was mainly the undisturbed model with a structure called translational symmetry, but in this study, the quantum many-body scar state that is stable against some kind of disorder is the first in the world exactly shown.<\/p>\n\n\n\n<p>It is expected that this research will open up new directions for future research on quantum many-body scar states and thermal equilibration, and lead to further development in these fields.<\/p>\n\n\n\n<p>See below for more information.<\/p>\n\n\n\n<ul><li>Katsura Lab. : <a href=\"http:\/\/park.itc.u-tokyo.ac.jp\/hkatsura-lab\/\">http:\/\/park.itc.u-tokyo.ac.jp\/hkatsura-lab\/<\/a><\/li><li>Aritcle URL : <a href=\"https:\/\/journals.aps.org\/prl\/abstract\/10.1103\/PhysRevLett.124.180604\">https:\/\/journals.aps.org\/prl\/abstract\/10.1103\/PhysRevLett.124.180604<\/a><\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"Naoyuki Shibata graduate student, Nobuyuki Yoshioka graduate student (at the time of research), and Associate  [&hellip;]","protected":false},"author":7,"featured_media":2203,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[29,10],"_links":{"self":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/2201"}],"collection":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=2201"}],"version-history":[{"count":2,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/2201\/revisions"}],"predecessor-version":[{"id":2204,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/2201\/revisions\/2204"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media\/2203"}],"wp:attachment":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=2201"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=2201"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=2201"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
