We know much less about entanglement in thermal equilibrium. This is because, at finite temperature, spatial correlations can be classical.\u00a0In this talk I will show how entanglement in equilibrium is related to linear response. This relation allows for conventional experiments to detect how entanglement emerges on different length scales. I will then show how techniques from quantum statistical mechanics and field theory can be used to lower bound the resources necessary to prepare equilibrium states.<br \/>\narXiv:2502.13218,\u00a0arXiv:2510.02275<br \/>\nhttps:\/\/indico.in2p3.fr\/event\/37943\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speakers: Samuel GARRATT (Princeton University) Studies of entanglement in the ground states of many-body systems have provided insights into the relation between spatial correlations, low-energy spectral properties, and the computational [&hellip;]<\/p>\n","protected":false},"author":8,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[],"class_list":["post-13080","tribe_events","type-tribe_events","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/13080","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/users\/8"}],"version-history":[{"count":2,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/13080\/revisions"}],"predecessor-version":[{"id":13085,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/13080\/revisions\/13085"}],"wp:attachment":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/media?parent=13080"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tags?post=13080"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events_cat?post=13080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
