论文摘要
在本文中，我们考虑了BTZ黑洞某些Z2商获得的时空的背景下的庞大矢量场。我们分析了物质场在时空几何形状上的背部反应，直到度量扰动中的一阶。应力 - 能量张量的期望值可以通过考虑其倾斜后的凹痕来计算到覆盖空间。在适当选择商围绕商歧管周期围绕矢量场上的边界条件时，可以通过导致可遍布的虫洞来获得无效的大地测量上的平均能量。
In this paper we consider a massive vector field in the background of a space-time obtained by certain Z2 quotient of the BTZ black hole. We analyse the back reaction of the matter field on the space-time geometry up to first order in metric perturbation. The expectation value of the stress-energy tensor can be computed exactly by considering its pull-back onto the covering space. Upon a suitable choice of the boundary condition on the vector field around a non-contractible cycle of the quotient manifold it is possible to obtain the average energy on a null geodesic to be negative there by resulting a traversable wormhole.
