论文摘要
WKB方法估算了宇宙弦周围围绕宇宙弦周围的共性标量场的能量密度。这种方法使用精确的模式-AM方法或镜像图像的方法再现了其他作者获得的确切值。近似值也与三维情况下的确切结果非常吻合。我们还以相同的方式评估了整体单极围绕共同不变标量场的能量密度，并再次找到已知的结果。
The energy density of a conformally invariant scalar field around a cosmic string is estimated by the WKB method. This approach reproduces the precise value obtained by the other authors using the exact mode-sum method or the method of mirror images. The approximation is also in good agreement with the exact result in the three-dimensional case. We also evaluate the energy density of a conformally invariant scalar field around a global monopole by the same way and find the known result again.
