关于膜上静态黑洞的存在性

On the existence of a static black hole on a brane

Hirotaka Yoshino

摘要:

我们研究了Randall-Sundrum(RS)II膜世界方案中的静态黑洞。为了解决这个问题的数值,我们开发了一个代码具有几乎四阶精度。该代码导出了膜张力为零的情况下的高度准确的结果,即,球对称的情况。然而,在膜张力非零的情况下,检测到非系统误差。这种误差是任何系统方法都无法消除的,例如提高分辨率,将外边界设置在更远的位置,或改善数值松弛的收敛性。我们讨论了非系统误差的可能来源,并得出结论,我们的结果自然被解释为不存在的解决方案,这种设置的证据,虽然一个“近似”的解决方案存在足够小的膜张力。我们讨论了在膜上产生的黑洞可能是不稳定的,并导致两个有趣的结果:事件视界箍缩和膜箍缩。

英文摘要:

We study a static black hole localized on a brane in the Randall-Sundrum (RS) II braneworld scenario. To solve this problem numerically, we develop a code having the almost 4th-order accuracy. This code derives the highly accurate result for the case where the brane tension is zero, i.e., the spherically symmetric case. However, a nonsystematic error is detected in the cases where the brane tension is nonzero. This error is irremovable by any systematic methods such as increasing the resolution, setting the outer boundary at more distant location, or improving the convergence of the numerical relaxation. We discuss the possible origins for the nonsystematic error, and conclude that our result is naturally interpreted as the evidence for the nonexistence of solutions to this setup, although an "approximate" solution exists for sufficiently small brane tension. We discuss the possibility that the black holes produced on a brane may be unstable and lead to two interesting consequences: the event horizon pinch and the brane pinch.
