DESCRIPTION:\n	Julien Vidal\n	(Sorbonne Université)\n\nAbstract:\n\n	The 
 string-net model introduced by M. Levin and X.-G. Wen in 2005 allows one t
 o generate all possible (bosonic) topological achiral phases in two dimens
 ions. In this talk\, I will explain how to compute the exact partition fun
 ction of this model and discuss the finite-temperature properties of sever
 al quantities such as the Wilson loops or the topological mutual informati
 on. These results show that\, in this context\, topological order can only
  survive up to a temperature which depends on the system size and goes to 
 zero in the thermodynamical limit.\n\n	Zoom registration link:https://zoom
