Magnetic excitations play a crucial role in understanding the color confinement of 4d Yang-Mills theory, and we have the monopole and the center vortex as plausible candidates to explain its mechanism. Under suitable compactified setups of 4d Yang-Mills theory, we can achieve different weakly-coupled descriptions of confinement phenomena: The monopole mechanism takes place on R³ S¹ with the double-trace deformation, and the center-vortex mechanism is effective on R² T² with the 't Hooft flux. We unify these two semiclassical descriptions by showing the explicit relation between the monopole and center vortex.
