用自由场塑造黑洞

Shaping black holes with free fields

Yannis Bardoux, Marco M. Caldarelli, Christos Charmousis

摘要:

从允许弱版本的Birkhoff定理的度量Angles出发,我们发现静态黑洞解,包括自由标量和p型场的形式,有和没有一个宇宙学常数Λ的物质。单p型物质场允许多种可能性,包括双子解,自对偶瞬子和爱因斯坦-凯尔赫视界的度量。另一方面,包含多个p-形式,相对于视界几何以均匀的方式排列,当Λ<0时,允许构造具有平坦视界的更高维双电子p-形式黑洞和四维轴电子黑洞。据发现,轴子领域正规化黑洞解的意义上,例如,允许定期-而不是奇异-小质量Reissner-Nordstrom型黑洞。它们的宇宙弦和Vaidya版本也得到了。

英文摘要:

Starting from a metric Ansatz permitting a weak version of Birkhoff's theorem we find static black hole solutions including matter in the form of free scalar and p-form fields, with and without a cosmological constant Λ. Single p-form matter fields permit multiple possibilities, including dyonic solutions, self-dual instantons and metrics with Einstein-Kaelher horizons. The inclusion of multiple p-forms on the other hand, arranged in a homogeneous fashion with respect to the horizon geometry, permits the construction of higher dimensional dyonic p-form black holes and four dimensional axionic black holes with flat horizons, when Λ<0. It is found that axionic fields regularize black hole solutions in the sense, for example, of permitting regular -- rather than singular -- small mass Reissner-Nordstrom type black holes. Their cosmic string and Vaidya versions are also obtained.
