Dual boundary conditions in 3d SCFT’s

We propose matching pairs of half-BPS boundary conditions related by IR dualities of 3d N=2$$ \mathcal{N}=2 $$ gauge theories. From these matching pairs we construct duality interfaces. We test our proposals by anomaly matching and the computation of supersymmetric indices. Examples include basic abelian dualities, level-rank dualities, and Aharony dualities.
