DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/136/">T
 opological symmetry and duality in quantum lattice models</a>\nby Clement 
 Delcamp (IHES) as part of Topological Quantum Field Theory Club (IST\, Lis
 bon)\n\n\nAbstract\nDefining internal symmetry in a quantum theory through
  the lens of topological defects opens the door to generalised notions of 
 symmetry\, including some arising from non-invertible transformations\, an
 d enables a calculus that leverages well-established methods from topologi
 cal quantum field theory. In d spatial dimensions\, the framework of fusio
 n d-category theory is believed to offer an axiomatisation for finite non-
 invertible symmetries. Though seemingly exotic\, such non-invertible symme
 tries can be shown to naturally arise as dual symmetries upon gauging inve
 rtible symmetries. In this talk\, I will present a framework to systematic
 ally investigate these aspects in quantum lattice models.\n
