论文摘要
我们首先提出光子的运动方程,耦合到Kerr Black Black SpaceTime中特殊的Bumblebee矢量场,并发现光的传播取决于其由于双折射现象而引起的极化。黑洞阴影对光的极化的依赖性由黑洞的旋转占主导地位。在非旋转情况下,我们发现黑洞阴影与光的极化无关。但是,在旋转情况下,状态发生了变化,在旋转情况下,黑洞阴影取决于光的极化以及Bumblebee矢量场和电磁场之间的耦合。通过极化灯铸造的黑洞阴影的这些特征可以帮助我们了解洛伦兹对称性破坏的大黄蜂矢量场及其与电磁场的相互作用。
We present firstly the equation of motion for the photon coupled to a special bumblebee vector field in a Kerr black hole spacetime and find that the propagation of light depends on its polarization due to the birefringence phenomenon. The dependence of black hole shadow on the light's polarization is dominated by the rotation of black hole. In the non-rotating case, we find that the black hole shadow is independent of the polarization of light. However, the status is changed in the rotating case, in which the black hole shadow depends on the light's polarization and the coupling between bumblebee vector field and electromagnetic field. These features of black hole shadow casted by polarized lights could help us to understand the bumblebee vector field with Lorentz symmetry breaking and its interaction with electromagnetic field.
