Defects in conformal field theory (CFT) are of significant theoretical andexperimental importance. The presence of defects theoretically enriches thestructure of the CFT, but at the same time, it makes it more challenging tostudy, especially in dimensions higher than two. Here, we demonstrate that therecently-developed theoretical scheme, fuzzy (non-commutative) sphereregularization, provides a powerful lens through which one can dissect thedefect of 3D CFTs in a transparent way. As a notable example, we study themagnetic line defect of 3D Ising CFT and clearly demonstrate that it flows to aconformal defect fixed point. We have identified 6 low-lying defect primaryoperators, including the displacement operator, and accurately extract theirscaling dimensions through the state-operator correspondence. Moreover, we alsocompute one-point bulk correlators and two-point bulk-defect correlators, whichshow great agreement with predictions of defect conformal symmetry, and fromwhich we extract various bulk-defect operator product expansion coefficients.Our work demonstrates that the fuzzy sphere offers a powerful tool forexploring the rich physics in 3D defect CFTs.
