具有标量或矢量毛的黑洞内部的最终卡斯纳区

The final Kasner regime inside black holes with scalar or vector hair

Marc Henneaux

摘要:

在一般的各向异性和非均匀初始条件下,分析了具有大质量带电标量或矢量毛的黑洞内部度规的最终(接近奇点)动力学行为。这些解与超导性的全息实现有关。结果表明,动态范围内的“宇宙学台球”的描述,在这两种情况下,相应的双曲台球区域具有无限大的体积,使系统最终解决了最后的卡斯纳政权。对于有质量的矢量头发,结论成立,因为纵向模式起着与标量场相同的作用。然而,存在一个测量零子集的解决方案,其特征在于消失的纵向模式,表现出一个混乱的行为与无限数量的BKL振荡作为一个去奇点。

英文摘要:

The final (close to the singularity) dynamical behavior of the metric inside black holes with massive charged scalar or vector hair is analyzed for general anisotropic and inhomogeneous initial conditions. These solutions are relevant to a holographic realization of superconductivity. It is shown that the dynamics falls within the scope of the "cosmological billiard" description and that in both cases, the corresponding hyperbolic billiard region has infinite volume so that the system ultimately settles down to a final Kasner regime. For massive vector hair, the conclusion holds because the longitudinal mode plays the same role as a scalar field. There exists, however, a measure-zero subset of solutions characterized by vanishing longitudinal modes that exhibit a chaotic behavior with an infinite number of BKL oscillations as one goes to the singularity.
