论文摘要
我们研究了在五维带电的静态静态挤压卡鲁扎 - 喀勒因黑洞时空中未磁化的冷均质等离子体培养基中光子的运动。在这种情况下，光子在四维球体对称的时空中表现为巨大的粒子。我们考虑了被压扁的卡鲁扎 - 克莱因黑洞的光偏转，该黑洞被弱场极限包围。我们得出缩小角度与一般相对性的校正，这与额外尺寸的大小，黑洞的电荷以及等离子体和光子频率之间的比率有关。
We study motions of photons in an unmagnetized cold homogeneous plasma medium in the five-dimensional charged static squashed Kaluza-Klein black hole spacetime. In this case, a photon behaves as a massive particle in a four-dimensional spherically symmetric spacetime. We consider the light deflection by the squashed Kaluza-Klein black hole surrounded by the plasma in a weak-field limit. We derive corrections of the deflection angle to general relativity, which are related to the size of the extra dimension, the charge of the black hole and the ratio between the plasma and the photon frequencies.
