A class of half-BPS boundary conditions for $A_{K - 1}$ circular quivers

Davide Bason, Roberto Valandro

We study a string-motivated class of $\frac{1}{2}$ -BPS boundary conditions for 4d $N = 2$ $A_{K - 1}$ circular quiver gauge theories with gauge group $S U (N)^{K}$ , engineered by D4-…

Half-Spacetime Gauging of 2-Group Symmetry in 3d

Davide Bason, Wei Cui, Lorenzo Ruggeri

We construct a class of non-invertible duality defects, in (2+1)d quantum field theories, arising from half-spacetime gauging of a 2-group symmetry. Starting from a parent theory w…
