相干量子黑洞的几何和热力学

Geometry and thermodynamics of coherent quantum black holes

Roberto Casadio

摘要:

我们提出了一个量子描述的黑洞的引力子的相干态来源于一个物质的核心。在视界外的弱场区域的预期行为恢复,任意好的近似,但经典的中心奇点没有解决,因为相干态可能不包含任意短波长的模式和物质的核心,因此必须有有限的大小。随后在内部和外部的量子校正也估计通过假设平均场近似保持无处不在。这些偏离经典黑洞几何的现象可以看作是量子头发,并导致了量子修正的视界半径和热力学。

英文摘要:

We present a quantum description of black holes given by coherent states of gravitons sourced by a matter core. The expected behaviour in the weak-field region outside the horizon is recovered, with arbitrarily good approximation, but the classical central singularity is not resolved because the coherent states may not contain modes of arbitrarily short wavelength and the matter core must therefore have finite size. Ensuing quantum corrections both in the interior and exterior are also estimated by assuming the mean-field approximation holds everywhere. These deviations from the classical black hole geometry can be viewed as quantum hair and lead to a quantum corrected horizon radius and thermodynamics.
