Abstract: Monodromy line defects are of interest in the defect bootstrap program and are dual to electrically charged objects in dual gauge field descriptions. We investigate the Ising monodromy dCFT using a fuzzy sphere regularization, by imposing the twisted boundary condition in the UV. We obtain defect scaling dimensions $\hat Δ$ and ratios of defect operator expansion (DOE) coefficients using this method. We extend this machinery to the continuous family of $O(2)$ monodromy defects with twist angle $2πν$. In both cases, the lowest neutral defect scalar lies above dimension one, providing evidence that the monodromy defect reaches a stable dCFT without additional fine tuning.
