A bstractBethe/gauge correspondence identifies supersymmetric vacua of massive gauge theories invariant under the two dimensional N$$ \mathcal{N} $$ = 2 Poincare supersymmetry with the stationary states of some quantum integrable system. The supersymmetric theory can be twisted in a number of ways, producing a topological field theory. For these theories we compute the handle gluing operator ℋ. We also discuss the Gaudin conjecture on the norm of Bethe states and its connection to ℋ.

The twisted index and topological saddles
Abstract The twisted index of 3d $$ \mathcal{N} $$ N = 2 gauge theories on S1× Σ has an algebro-geometric interpretation as the Witten index of an effective supersymmetric quantum mechanics. In
