AbstractRecently, vertex operator algebras from 3d supersymmetric theories gained a lot of attention. One way to study them directly is using twisted formalism and compute OPE. We are going to review [2204.02997] (with relevant references) from scratch to utilize this technique to research holomorphically or topologically twisted SQFTs in 3d
AbstractIn this talk, we will present how a Heisenberg spin chain emerges from the two-dimensional N=(2,2) gauge theory at an intermediate scale, which relies on the renormalization group flow guided by the global symmetries and the dynamics of domain walls. Two examples will be discussed: XX-model and its K-theoretic version. Finally, we will briefly comment on the unification of gauge theorie...
