Kazhdan-Lusztig Correspondence for Vertex Operator Superalgebras from Abelian Gauge Theories

We prove the Kazhdan-Lusztig correspondence for a class of vertex operator superalgebras which, via the work of Costello-Gaiotto, arise as boundary VOAs of topological B twist of 3d $\mathcal{N}=4$ abelian gauge theories. This means that we show equivalences of braided tensor categories of modules of certain affine vertex superalgebras and corresponding quantum supergroups. We build on the work of Creutzig-Lentner-Rupert to this large class of VOAs and extend it since in our case the categories don't have projective objectives and objects can have arbitrary Jordan Hölder length. Our correspondence significantly improves the understanding of the braided tensor category of line defects associated to this class of TQFT, by realizing line defects as modules of a Hopf algebra. In the process, we prove a case of the conjecture of Semikhatov-Tipunin, relating logarithmic CFTs to Nichols algebras of screening operators.
