Abstract: We study self-duality symmetries in free compact boson and Maxwell theory, with a focus on their kinematic implications in the twisted Hilbert space and the monodromy defect. For the compact boson and similar theories in $d=4n+2$ dimensions, we demonstrate how the zero mode quantization of the twisted Hilbert space is settled from the half-gauging topological defect. Fusion rules, g-functions, and related aspects of such defects in free compact boson are also discussed. For the Maxwell and similar theories in $d=4n$ dimensions, we find that the analog of zero modes resides at the codim-2 boundary of the half-gauging defect. The DCFT of such a monodromy defect in Maxwell theory comprises a rigid, chiral, generalized free theory sector and a decoupled chiral current sector, which we investigated in detail.
