量子几何中非广延统计力学与黑洞熵

Non-extensive Statistical Mechanics and Black Hole Entropy From Quantum Geometry

Abhishek Majhi

摘要:

利用非广延统计力学,对任意实正值的Barbero-Immirzi参数$(γ)$,从圈量子引力中黑洞的微观态得到了Bekenstein-Hawking面积定律. $γ$的任意性被编码在通过与视界外部的量子几何场耦合而在视界微观态中产生的“偏置”的强度中。$γ$的实验测定将修正这种耦合,而把黑洞的宏观区域作为理论中唯一的自由量。

英文摘要:

Using non-extensive statistical mechanics, the Bekenstein-Hawking area law is obtained from microstates of black holes in loop quantum gravity, for arbitrary real positive values of the Barbero-Immirzi parameter$(γ)$. The arbitrariness of $γ$ is encoded in the strength of the "bias" created in the horizon microstates through the coupling with the quantum geometric fields exterior to the horizon. An experimental determination of $γ$ will fix this coupling, leaving out the macroscopic area of the black hole to be the only free quantity of the theory.
