论文摘要
我们构建了一个由各向异性物质流体支撑的渐近平坦的Morris-Thorne虫洞溶液和一个矢量场，该矢量场与重力偶联，并以非最小程度的方式与损坏的Abelian仪表对称性。在本文中，考虑了特定的形状函数。我们发现，矢量场的Ansatz在确定虫洞的时空几何形状中起着重要作用。如果仅存在静电电势，则可以将红移函数视为恒定值，这意味着消失的潮汐力。但是，当涉及径向方向的矢量电位时，虫洞喉咙延伸的麦克斯韦方程的R分量无效。为了解决这个问题，在喉咙附近引入了一个薄壳，将时空分为两个部分。此外，如果适当地给出了红移功能和矢量电势的表达，则证明虫洞的时空几何形状在连接位置可以平滑。最后，探索了能量条件和体积积分量化器。
We construct an asymptotically flat Morris-Thorne wormhole solution supported by anisotropic matter fluid and a vector field which is coupled to gravity in a non-minimal way with broken Abelian gauge symmetry. In this paper, a specific shape function is considered. We find that the ansatz of vector field plays a significant role in determining the spacetime geometry of the wormhole. If there exists the electrostatic potential only, the redshift function could be considered as a constant value, implying the vanishing tidal force. However, when the vector potential in radial-direction is involved, the r-component of extended Maxwell equations at the wormhole's throat is invalid. To solve this issue, a thin shell is introduced near the throat, dividing the spacetime into two parts. Furthermore, it is proved that the spacetime geometry of wormhole could be smooth at junction position if the expressions of redshift function and vector potential are given appropriately. Finally, the energy conditions and the volume integral quantifer are explored.
