  6. The one - loop vacuum polarization is calculated for untwisted and twisted scalar fields in a flat space - time with the topology s1 r3. the effect of vacuum polarization upon photon propagation is considered. it is found that for the untwisted scalar field some photon modes acquire a positive topological mass, thus travelling at a subluminal speed ; but for the twisted scalar field some photon modes get an imaginary topological mass and travel at a superluminal speed

    本文中我們首先計算了在拓撲結構為s ~ 1 r ~ 3的非minkowski時空中扭曲標量場和非扭曲標量場的真空極化，然後考慮了真空極化對光子傳播的影響，我們發現除了光子的極化方向和傳播方向都垂直於緊致化方向的情形之外，非扭曲標量場的真空極化使所有其他的光子模式都獲得實的拓撲質量從而導致這些光子以亞光速傳播；但是，扭曲標量場的真空極化使光子獲得虛的拓撲質量以致他們以超光速傳播。
