Intersecting Surface Defects and Instanton Partition Functions
Yiwen Pan, Wolfger Peelaers
We analyze intersecting surface defects inserted in interacting four-dimensional N = 2 supersymmetric quantum field theories. We employ the realization of a class of such systems a…
Intersecting Surface Defects and Two-Dimensional CFT
Jaume Gomis, Bruno Le Floch, Yiwen Pan +1
We initiate the study of intersecting surface operators/defects in four-dimensional quantum field theories (QFTs). We characterize these defects by coupled 4d/2d/0d theories constr…
Deformation quantization and superconformal symmetry in three dimensions
Christopher Beem, Wolfger Peelaers, Leonardo Rastelli
We investigate the structure of certain protected operator algebras that arise in three-dimensional N=4 superconformal field theories. We find that these algebras can be understood…
