本文利用一种新的方法,求解了运动项为反号标量场(幻影场)的爱因斯坦方程,得到了一系列推导广义相对论中幻影场的轴对称定态精确解的公式。我专注于代表虫洞的解决方案。在这项工作中提出的程序可以得到新的精确解非常简单的集成。在其他结果中,我发现精确的旋转解决方案,包含磁单极子,偶极子等,耦合到幻影标量和重力多极场。
Using a new ansatz for solving the Einstein equations with a scalar field with inverted sign in the kinetic term (phantom field), I find a series of formulae to derive axial symmetric stationary exact solutions of the phantom fields in general relativity. I focus on the solutions which represent wormholes. The procedure presented in this work allows to derive new exact solutions up to very simple integrations. Among other results, I find exact rotating solutions containing magnetic monopoles, dipoles, etc., coupled to phantom scalar and to gravitational multipole fields.
