In the first half of the talk, I will review the notion of non-invertible symmetries and how they help us to analyze certain strongly coupled QFTs like 2d Adjoint QCD. Then, I discuss the representation theory of non-invertible symmetries and use it...

Astronomical observations indicate that coherent, dynamically important magnetic fields are ubiquitous in the Universe. However, neither the origin problem -- what are the physical mechanisms that generate the initial ``seed'' magnetic fields —- nor...
