Moreover, since the TRG can directly deal with the Grassmann variables, this approach can be formulated in the same manner for the systems with bosons, fermions, or both. These advantages of the TRG approach have been confirmed by the earlier studies of various lattice theories, which suggest that the TRG potentially enables us to investigate the parameter regimes where it is difficult to access with the standard stochastic numerical methods, such as the Monte Carlo simulation.<br \/>In this talk, explaining our recent applications of the TRG approach to several (3+1)-dimensional field theories on a lattice, we demonstrate the efficiency of the TRG as a tool to investigate higher-dimensional theories and future perspective.<\/p>\n<p><a href=\"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2022\/05\/akiyama_2022_0526.pdf\"><strong>PDF<\/strong><\/a><\/p>\n<div><span class=\"x_author-d-iz88z86z86za0dz67zz78zz78zz74zz68zjz80zz71z9iz90z8z86zdnagz83zz74zikpz70zz72zkz79zkfbz71z2z88zz74zm9gxc1z74zz79zk\">*To receive the Zoom invitation and monthly reminders,<span class=\"x_Apple-converted-space\">\u00a0<\/span><\/span><span class=\"x_author-d-iz88z86z86za0dz67zz78zz78zz74zz68zjz80zz71z9iz90z8z86zdnagz83zz74zikpz70zz72zkz79zkfbz71z2z88zz74zm9gxc1z74zz79zk\"><b>please register via this google form<\/b><\/span><span class=\"x_author-d-iz88z86z86za0dz67zz78zz78zz74zz68zjz80zz71z9iz90z8z86zdnagz83zz74zikpz70zz72zkz79zkfbz71z2z88zz74zm9gxc1z74zz79zk\">:<span class=\"x_Apple-converted-space\">\u00a0<\/span><\/span><span class=\"x_attrlink x_url x_author-d-iz88z86z86za0dz67zz78zz78zz74zz68zjz80zz71z9iz90z8z86zdnagz83zz74zikpz70zz72zkz79zkfbz71z2z88zz74zm9gxc1z74zz79zk x_url\"><a class=\"x_attrlink\" href=\"https:\/\/forms.gle\/dqxhpsZXLNYvbSB38\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" data-auth=\"NotApplicable\"><u>https:\/\/forms.gle\/dqxhpsZXLNYvbSB38<\/u><\/a><\/span><\/div>\n<div><span class=\"x_author-d-iz88z86z86za0dz67zz78zz78zz74zz68zjz80zz71z9iz90z8z86zdnagz83zz74zikpz70zz72zkz79zkfbz71z2z88zz74zm9gxc1z74zz79zk\">Your e-mail addresses will be used for this purpose only, you can unsubscribe anytime, and we will not send more than three e-mails per month.<\/span><\/div>\n<div>\u00a0<\/div>\n<div>Tilman HARTWIG, Takashi TAKAHASHI &amp; Ken NAKANISHI<\/div>\n<div>\u00a0<\/div>\n<div><a href=\"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/lp\/ipi\/\">\u21e6Top page<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"\u77e5\u306e\u7269\u7406\u5b66\u7814\u7a76\u30bb\u30f3\u30bf\u30fc \/ Institute for Physics of Intelligence (ipi) \u3010Speaker\u3011Shinichiro AKIYAMA@The University of Tokyo  [&hellip;]","protected":false},"author":13,"featured_media":3595,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[22,4],"tags":[],"_links":{"self":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3593"}],"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\/13"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=3593"}],"version-history":[{"count":8,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3593\/revisions"}],"predecessor-version":[{"id":3626,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3593\/revisions\/3626"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media\/3595"}],"wp:attachment":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=3593"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=3593"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=3593"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
