DESCRIPTION:Speakers: Andrea Antinucci (University of Oxford & IHES)\n\nPh
 ases of matter and the transitions between them are famously characterized
  within the Landau paradigm and Landau–Ginzburg theory: phases are label
 ed by broken or unbroken symmetries\, while phase transitions are describe
 d in terms of scalar order parameters. There are\, however\, phases beyond
  the standard Landau paradigm that are distinguished not by the realizatio
 n of ordinary symmetries\, but by that of generalized global symmetries. A
 mong these\, topologically ordered phases in (2+1)d possess non-invertible
  1-form symmetries described by anyon lines. In this talk\, I will present
  a framework for describing transitions between topologically ordered phas
 es related by anyon proliferation\, which can be viewed as a non-invertibl
 e generalization of the choice of the unbroken symmetry. The resulting the
 ories involve scalar fields coupled to gauge fields. A crucial ingredient 
 in this construction is the (3+1)d Symmetry Topological Field Theory (SymT
 FT)\, which allows to separate symmetry from dynamics and will be employed
  in a rather unconventional way.\n \nPour être informé des prochains s
