This study theoretically demonstrates a cooling method employing multi-component Fermi gases with SU(N)-symmetric interactions, focusing on the case of 173Yb atoms in a two-dimensional optical lattice. Adiabatically introducing a nonuniform state-selective laser gives rise to two distinct subsystems: a central low-temperature region, exclusively composed of two specific spin components, acts as a quantum simulator for SCESs, while the surrounding N-component mixture retains a significant portion of the entropy of the system. The SU(N)-symmetric interactions ensure that the total particle numbers for each component become good quantum numbers, creating a sharp boundary for the two-component region. The cooling efficiency is assessed through extensive finite-temperature Lanczos calculations. The results lay the foundation for quantum simulations of two-dimensional systems of Hubbard or Heisenberg type, offering crucial insights into intriguing low-temperature phenomena in condensed-matter physics.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u6771\u4eac\u7406\u79d1\u5927\u3068\u306e\u5171\u540c\u7814\u7a76\u306e\u6210\u679c\u8ad6\u6587\u3092arXiv\u306b\u4e0a\u3052\u307e\u3057\u305f\u3002 \u30bf\u30a4\u30c8\u30eb\uff1aEngineering of a Low-Entropy Quantum Simulator for Strongly Correlated Elec [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","footnotes":""},"categories":[7],"tags":[],"class_list":["post-1267","post","type-post","status-publish","format-standard","hentry","category-publication"],"_links":{"self":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1267","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/comments?post=1267"}],"version-history":[{"count":1,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1267\/revisions"}],"predecessor-version":[{"id":1268,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1267\/revisions\/1268"}],"wp:attachment":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/media?parent=1267"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/categories?post=1267"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/tags?post=1267"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
