LQG:孤立视界框架中的黑洞辐射谱

Black hole radiation spectrum in LQG: Isolated Horizon framework

Jacobo Diaz-Polo, Enrique Fernandez-Borja

摘要:

最近在圈量子引力中对黑洞熵的计算的详细分析表明,熵作为视界面积的函数的行为中存在阶梯状结构。黑洞视界区域本征态简并度的非平凡分布是这种行为的起源。分析了这种简并分布,并提出了一个唯象模型来研究这种分布在黑洞辐射谱中的意义。在孤立视界框架下得到了一些定性的量子效应。这一结果为我们提供了一个可能的量子黑洞模型的观测检验。

英文摘要:

Recent detailed analysis within the Loop Quantum Gravity calculation of black hole entropy shows a stair-like structure in the behavior of entropy as a function of horizon area. The non-trivial distribution of the degeneracy of the black hole horizon area eigenstates is at the origin of this behavior. This degeneracy distribution is analyzed and a phenomenological model is put forward to study the implications of this distribution in the black hole radiation spectrum. Some qualitative quantum effects are obtained within the isolated horizon framework. This result provides us with a possible observational test of this model for quantum black holes.
