SUMMARY:Kramers-Wannier-like duality defects in higher dimensions
DESCRIPTION:Title: Kramers-Wannier-like duality defects in higher dimensions \nAbstract: I will introduce a class of non-invertible topological defects in (3 + 1)d gauge theories whose fusion rules are the higher-dimensional analogs of those of the Kramers-Wannier defect in the (1 + 1)d critical Ising model. As in the lower-dimensional case\, the presence of such non-invertible defects implies self-duality under a particular gauging of their discrete (higher-form) symmetries. Examples of theories with such a defect include SO(3) Yang-Mills (YM) at θ = π\, N = 1 SO(3) super YM\, and N = 4 SU(2) super YM at τ = i. I will also explain an analogous construction in (2+1)d\, and give a number of examples in Chern-Simons-matter theories. This talk is based on https://arxiv.org/abs/2111.01141.
