摘要:

虫洞是时空中最有趣的拓扑特征之一,在宇宙的两个巨大分离的区域之间提供了一个老鼠跑。本文在弱场极限近似下研究了由电荷、磁荷和标量场支撑的虫孔对光的偏转角。为此,我们应用新的几何方法-高斯-博内定理和光学几何-来计算偏转角。我们还验证了我们的研究结果,使用著名的测地线方法。最近在相对论性玻姆量子力学中讨论了黑洞解的电荷修正和量子修正之间的相似性。通过用玻姆轨道代替经典测地线,引入了一种新的虫洞解,它具有物质源和各向异性压力,并得到了玻姆量子效应的支持。本文还讨论了Morris-Thorne可穿越虫洞的能量条件的满足问题。

英文摘要:

Wormholes are one of the most interesting topological features in spacetime, offering a rat run between two vastly separated regions of the universe. In this paper, we study the deflection angle of light by wormholes, which are supported by electric charge, magnetic charge, and scalar fields in the weak field limit approximation. To this end, we apply new geometric methods -- the Gauss-Bonnet theorem and the optical geometry -- to compute the deflection angles. We also verify our findings by using the well-known geodesics method. There exists a similarity between the charge and the quantum corrections on a black hole solution, which has been recently discussed in the context of the relativistic Bohmian quantum mechanics. By replacing classical geodesics with Bohmian trajectories, we introduce a new wormhole solution, whose having matter sources and anisotropic pressure supported by Bohmian quantum effects. The problem of fulfillment of the energy conditions of the Morris-Thorne traversable wormhole is also discussed.
