论文摘要
我们在Randall-Sundrum II场景中的3-武器上,在有效的爱因斯坦方程中构建了具有四维宇宙常数的新型解决方案。通过假设在3大志上存在局部麦克斯韦场来获得带电的解决方案。讨论了带有螺母参数的中性旋转Braneworld时空中的时机和无循环大地测量学,我们发现赤道平面上不能出现此类测量学。在非赤道平面上,可能会出现负潮汐电荷的圆形圆形测量学,但我们找不到数值结果来支持非赤道零循环圆形测量学的存在。
We construct novel solutions to the effective Einstein equation with four dimensional cosmological constant on a 3-brane in Randall-Sundrum II scenario. The charged solution is obtained by assuming the existence of localized Maxwell fields on the 3-brane. Timelike and null circular geodesics in the neutral rotating braneworld spacetime with NUT parameter are discussed, and we find that such geodesics cannot occur on the equatorial plane. On non-equatorial planes, timelike circular geodesics can occur for the negative tidal charge, but we cannot find numerical results to support the existence of non-equatorial null circular geodesics.
