We investigate the Maxwell–Chern–Simons (MCS) theory in (2+1)-dimensional spacetime confined within a rotating finite disk. Starting from a review of electrodynamics in lower dimensions, we formulate the field equations incorporating both the Chern–Simons term and the effects of rotation. Imposing boundary conditions that enforce the vanishing of the magnetic field at the edge of the disk, we obtain a discrete energy spectrum, effectively quantizing the system. Our analysis reveals that the quantized energy levels are sensitive to both the topological mass and the angular velocity of the system. In particular, the spectra exhibit a marked asymmetry under the reversal of the rotation direction, a direct manifestation of the parity-violating nature of the Chern–Simons term. These findings demonstrate a nontrivial interplay between topological field theory and rotational dynamics, suggesting a broader class of physical systems where topology and geometry together govern spectral properties. Our results extend previous studies on topological mass generation in static backgrounds and provide new insight into parity asymmetry in rotating gauge systems.
