Garban. KT or topological phase transitions are a type of\u00a0 phase transition discovered by Kosterlitz and Thouless in the \u201970s. Models that undergo this phenomenon are typically 2-dimensional and do not have a classical phase transition. In this talk, I will explain this type of phase transition going over the first proof of their existence by Fr\u00f6hlich and Spencer which relates them to the localization of random surfaces. Then, I will discuss a new interpretation of this phase transition that arises from the following question: Let \\(\\phi\\) be a discrete Gaussian free field at temperature \\(T\\) and imagine that you lost its integer part, can you recover the macroscopic information of \\(\\phi\\)?.<\/p>\n<p><strong>Venue:<\/strong> Online via Zoom<br \/>\n<strong>Coordinators:<\/strong> Prof. Joaqu\u00edn Fontbona &amp; Prof. Daniel Remenik<\/p>\n<div><\/div>\n<p><a href=\"https:\/\/drive.google.com\/file\/d\/1G0at0IV6zqlwwscbga5Mln-m2f7F_D9L\/view?usp=sharing\">Video<\/a><\/p>\n<div id=\"gtx-trans\" style=\"position: absolute; left: -2px; top: 3px;\">\n<div class=\"gtx-trans-icon\"><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Avelio Sep\u00falveda, CMM, Universidad de Chile.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[4,3],"tags":[],"class_list":["post-47","post","type-post","status-publish","format-standard","hentry","category-past-seminar","category-seminar"],"_links":{"self":[{"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/posts\/47","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/comments?post=47"}],"version-history":[{"count":23,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/posts\/47\/revisions"}],"predecessor-version":[{"id":96,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/posts\/47\/revisions\/96"}],"wp:attachment":[{"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/media?parent=47"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/categories?post=47"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/eventos.cmm.uchile.cl\/probseminar\/wp-json\/wp\/v2\/tags?post=47"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
