具有Klein-Gordon场的精确动力学AdS黑洞和虫洞

Exact dynamical AdS black holes and wormholes with a Klein-Gordon field

Hideki Maeda

摘要:

本文给出了具有宇宙学常数的Einstein-Klein-Gordon系统的几类精确解。时空具有球面、平面或双曲对称性,高维解仅在平面对称的情况下才以封闭形式得到。其中,第一类解代表了一个渐进局部反德西特(AdS)动力学黑洞或虫洞。在四维和更高维中,广义的米斯纳-夏普准定域质量在AdS无穷远处爆炸,这意味着时空只是局部的AdS。在三维空间中,标量场变得平凡,解简化为BTZ黑洞。

英文摘要:

We present several classes of exact solutions in the Einstein-Klein-Gordon system with a cosmological constant. The spacetime has spherical, plane, or hyperbolic symmetry and the higher-dimensional solutions are obtained in a closed form only in the plane symmetric case. Among them, the class-I solution represents an asymptotically locally anti-de Sitter (AdS) dynamical black hole or wormhole. In four and higher dimensions, the generalized Misner-Sharp quasi-local mass blows up at AdS infinity, inferring that the spacetime is only locally AdS. In three dimensions, the scalar field becomes trivial and the solution reduces to the BTZ black hole.
