摘要:

本文研究了由三形式场支撑的可穿越虫洞对光的偏转角。我们使用了在虫洞喉部与能量条件兼容的红移函数和形状函数的具体形式。利用三形式虫洞的明确定义参数集,我们研究了虫洞背景有效势下的光子测地运动。结果发现,光子球半径是一个非常有用的可观测量,可用于分析物理虫洞的几何结构。

英文摘要:

In this paper, we study the deflection angle of light by traversable wormholes, which are supported by the three-form fields. The specific forms of the redshift and shape functions that produce results compatible with the energy conditions at throat of the wormholes are used. Having used the well-defined parameter sets of the three-form wormholes, we investigate the photon geodesic motion under the effective potential of the wormhole background. As a result, we discover that the radius of the photon sphere is a very useful observable that is used to analyze the geometrical structures of a physical wormhole.
