论作为宏观量子物体的黑洞

On black holes as macroscopic quantum objects

De-Chang Dai, Djordje Minic, Dejan Stojkovic

摘要:

在史瓦西坐标系中坍缩壳的经典演化过程中,史瓦西相对于适当时间的相对流动实际上迫使我们将黑洞的形成解释为一个高度非定域的量子过程,在这个过程中,在初始视界内产生了一个壳/反壳对,从而恰好在视界处抵消了原来的坍缩壳。通过研究黑洞背景中的量子场,我们揭示了类似的非局域效应。除此之外,霍金对的出射成员很快就与黑洞几何(而不是它的伙伴)纠缠在一起,这与通常的假设相反,根据视界附近的局部几何,霍金对是最大纠缠的。此外,下落波甚至在穿过视界之前就影响了黑洞的几何形状。最后,我们发现一个粒子需要有限的时间隧道进出黑洞视界,从而避免了无限的蓝移和红移的过程正好发生在视界。这些发现有力地支持了黑洞是宏观量子物体的观点。

英文摘要:

The relative flow of the Schwarzschild vs. the proper time during the classical evolution of a collapsing shell in the Schwarzschild coordinates practically forces us to interpret black hole formation as a highly non-local quantum process in which a shell/anti-shell pair is created within the incipient horizon, thus canceling out the original collapsing shell exactly at the horizon. By studying quantum fields in the black hole background, we reveal similar non-local effects. Among other things, the outgoing member of the Hawking pair very quickly becomes entangled with the black hole geometry (and not its partner), which is in contrast with the usual assumption that the Hawking pair is maximally entangled according to the local geometry near the horizon. Also, an infalling wave affects the black hole geometry even before it crosses the horizon. Finally, we find that a particle takes a finite amount of time to tunnel in and out of the black hole horizon, and thus avoids infinite blue and redshift in processes happening exactly at the horizon. These findings strongly support the picture of a black hole as a macroscopic quantum object.
