用虚标量场平衡静态黑环

Balancing a static black ring with a phantom scalar field

Burkhard Kleihaus, Jutta Kunz, Eugen Radu

摘要:

所有已知的五维渐近平坦静态黑环都具有圆锥奇点。然而,没有根本的障碍,禁止平衡配置的存在,我们表明,爱因斯坦-克莱因-戈登方程承认(数值)的解决方案描述静态渐近平坦的黑环,这是经常的事件视界内外。标量场是“幻影”,它产生了平衡黑环所必需的自排斥。类似的解决方案很可能存在于其他时空维度,一个线元素描述一个四维的基本属性,渐近平坦的黑环几何进行了讨论。

英文摘要:

All known five dimensional, asymptotically flat, static black rings possess conical singularities. However, there is no fundamental obstruction forbidding the existence of balanced configurations, and we show that the Einstein--Klein-Gordon equations admit (numerical) solutions describing static asymptotically flat black rings, which are regular on and outside the event horizon. The scalar field is 'phantom', which creates the self-repulsion necessary to balance the black rings. Similar solutions are likely to exist in other spacetime dimensions, the basic properties of a line element describing a four dimensional, asymptotically flat black ring geometry being discussed.
