论文摘要
在Einstein-yang-Mills-higgs理论的Bogomol'nyi-Prasad-Sommerfield（BPS）限制中，我们从数值上构造了一个由幻影场支持的非亚伯虫孔。当重力关闭时，探针极限是Ellis虫洞背景中的Yang-Mills-Higgs字段。在重力存在下，虫洞溶液具有阳米尔斯·希格斯的头发。因此，当重力耦合常数增加时，毛孔虫溶液的一个分支从埃利斯虫洞出现。我们发现，当引力耦合常数增加时，幻影场的质量和标量电荷会单调增加。当重力强度超过临界值时，虫洞时空具有双喉构型。令人惊讶的是，蠕虫在较大的引力强度下满足了无效的能量条件。我们还简要讨论红移因子。
In the Bogomol'nyi-Prasad-Sommerfield (BPS) limit of Einstein-Yang-Mills-Higgs theory, we construct numerically a non-Abelian wormhole supported by a phantom field. The probe limit is the Yang-Mills-Higgs field in the background of Ellis wormhole when the gravity is switched off. The wormhole solutions possess the Yang-Mills-Higgs hair in the presence of gravity; Thus a branch of hairy wormhole solutions emerge from the Ellis wormhole when the gravitational coupling constant increases. We find that the mass of wormholes and scalar charge of phantom field increase monotonically when the gravitational coupling constant increases. The wormhole spacetime possesses double throat configuration when the gravitational strength exceeds a critical value. Surprisingly, the wormholes satisfy the null energy condition in the large gravitational strength. We also briefly discuss the redshift factor.
