DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/61/">
 Cluster state as a non-invertible SPT phase</a>\nby Sahand Seifnashri (IAS
 ) as part of Symmetry Seminar\n\n\nAbstract\nWe study the simplest lattice
  realizations of SPT phases protected by non-invertible symmetries. We sho
 w that the well-known 1+1d cluster model has a Rep(D8) non-invertible symm
 etry\, thereby identifying it as a non-invertible SPT phase. We also find 
 commuting Pauli Hamiltonians for the remaining two Rep(D8) SPT phases\, ma
 tching the classification in field theory and mathematics. Finally\, we de
 termine the projective algebra and edge modes at the interfaces between th
 ese three non-invertible SPT phases.\n
