Solving Conformal Defects in 3D Conformal Field Theory using Fuzzy Sphere Regularization
Liangdong Hu, Yin-Chen He, W. Zhu
Defects in conformal field theory (CFT) are of significant theoretical and experimental importance. The presence of defects theoretically enriches the structure of the CFT, but at…
