摘要： The one-loop vacuum polarization is calculated for scalar electrodynamics in a flat space－time with the topology S1×R3. The effect of vacuum polarization upon photon propagation is considered. It is found that photon propagation becomes anisotropic with some photon modes acquiring a positive topological mass and thus travelling at a subluminal speed.
