Non-invertible SPT phases from fusion rings via Tannaka duality
Antonio Santaniello, Roberto Valandro, Massimo Zorzenon
In a (1+1)-dimensional QFT with non-invertible symmetry, the fusion rules of topological lines are often the most accessible data, yet they do not fully determine whether the symme…

Symmetry extension by condensation defects II: general dimensions and higher-groups
Matteo Bertolini, Lorenzo Di Pietro, Stefano C. Lanza +1
We discuss a class of symmetry structures in general spacetime dimension that arise when gauging symmetries in theories with a cubic 't Hooft anomaly. The anomaly mixes two Abelian…

Symmetry extension by condensation defects in five-dimensional gauge theories
Matteo Bertolini, Lorenzo Di Pietro, Stefano C. Lanza +2
We investigate the symmetry structure of five-dimensional Yang-Mills theories with gauge algebra. These theories feature intertwined 0-, 1-, and 2-form symmetrie…
