从普朗克面积到图论:拓扑上不同的黑洞微观态

From Planck area to graph theory: Topologically distinct black hole microstates

Aharon Davidson

摘要:

我们假设一个普朗克尺度的视界单位面积,没有任何局部的信息附着在它上面,它是连接的,但在其他方面是自由的形式,让$n$这样的几何单位compatible的黑洞视界。与每个拓扑上不同的平铺配置相关联的是简单的、连通的、无向的、无标签的、平面的弦图。相应的整数序列的渐近计数产生了贝肯斯坦-霍金面积熵公式,自动伴随着一个适当的对数项,并固定了视界单位面积的大小,从而构成了惠勒“它来自比特”短语的整体实现。利用Polya定理,给出了2+1维量子黑洞的精确数论熵谱.

英文摘要:

We postulate a Planck scale horizon unit area, with no bits of information locally attached to it, connected but otherwise of free form, and let $n$ such geometric units compactly tile the black hole horizon. Associated with each topologically distinct tiling configuration is then a simple, connected, undirected, unlabeled, planar, chordal graph. The asymptotic enumeration of the corresponding integer sequence gives rise to the Bekenstein-Hawking area entropy formula, automatically accompanied by a proper logarithmic term, and fixes the size of the horizon unit area, thereby constituting a global realization of Wheeler's "it from bit" phrase. Invoking Polya's theorem, an exact number theoretical entropy spectrum is offered for the 2+1 dimensional quantum black hole.
