研究了自发破缺规范理论与引力相互作用的荷磁经典解。我们表明,非奇异的Higgs场的真空期望值v是小于或等于一个临界值v分cr,这是普朗克质量的顺序,只有当Higgs场的真空期望值v是存在的。在极限情况下,黑洞变成黑洞,视界外的区域由临界Reissner-Nordstrom解描述。对于v小于v sub cr,我们找到了在f = 0处奇异的附加解,但这些解的奇异性隐藏在视界内。这些黑洞在视界外有非平凡的物质场,可以解释为位于磁层内的小黑洞。这些解决方案作为一个功能的V和总质量M和Reissner-Nordstrom解决方案的关系的性质进行了讨论。
We study magnetically charged classical solutions of a spontaneously broken gauge theory interacting with gravity. We show that nonsingular monopole solutions exist only if the Higgs field vacuum expectation value v is less than or equal to a critical value v sub cr, which is of the order of the Planck mass. In the limiting case, the monopole becomes a black hole, with the region outside the horizon described by the critical Reissner-Nordstrom solution. For v less than v sub cr, we find additional solutions which are singular at f = 0, but which have this singularity hidden within a horizon. These have nontrivial matter fields outside the horizon, and may be interpreted as small black holes lying within a magnetic monopole. The nature of these solutions as a function of v and of the total mass M and their relation to the Reissner-Nordstrom solutions is discussed.
