A special form of electrodynamical response to a gravitational wave：outgoing and imploding photon fluxes

We have investigated the interaction of an electromagnetic (EM) wave with a standing gravitational wave (GW) in an external static magnetic field,and obtained concrete forms of first-order perturbative EM energy fluxes.Unlike the propagating properties of the “left-circular” and “right-circular” waves of the tangential perturbative energy fluxes around the symmetrical axis,the radial perturbative energy fluxes are expressed as the outgoing and imploding waves to the symmetrical axis.We also examine several physical examples and show that this effect can produce very small but nonvanishing radial perturbative photon fluxes.This may be useful for EM detection of the high-frequency relic GWs of the GHz region in quintessential inflationary models.     

光子静质量及检测方法

 一、检测光子静质量的意义首先,这对狭义相对论是一个很好的检验。我们知道,比起“惯性系地位等价”来说,“光速不变原理”在狭义相对论的理论基础中显得有些突兀,好像是爱因斯坦(Einstein)为使麦克斯韦(Maxwell)方程满足洛仑兹(Lorentz)协变而直接塞入的。不过非常凑巧的是,麦克斯韦电磁场方程刚好能够预言所有的电磁辐射在真空中都以相同的速度c传播,且与其频率无关。
