Rank-one 4d SCFTs: Schur index, VOA modules, and modularity
Zhaoting Guo, Satoshi Nawata, Yiwen Pan +1
We study the representation theory of the vertex operator algebras (VOAs) associated with rank-one 4d superconformal field theories. For the S-fold…

Lagrangian Schur index and Bethe ansatz type formula
Yutong Li, Yiwen Pan
We propose a surprisingly elementary method to compute the Schur index in closed-form for general Lagrangian theories. The method is inspired by the Bethe ansatz…
