One-form symmetries and the 3d $\mathcal{N}=2$ $A$-model: Topologically twisted indices and CS theories

Cyril Closset, Elias Furrer, Osama Khlaif

We study three-dimensional $\mathcal{N}=2$ supersymmetric Chern-Simons-matter gauge theories with a one-form symmetry in the $A$-model formalism on ${\Sigma }_g\times S^1$. We explicitly c…
