Voros乘积、非对易Reissner-Nordstr{<$}m黑洞和修正的面积定律

Voros product, noncommutative inspired Reissner-Nordstr{ö}m black hole and corrected area law

Sunandan Gangopadhyay, Dibakar Roychowdhury

摘要:

我们强调的重要性,Voros产品在定义一个非对易启发Reissner-Nordström黑洞。这个黑洞的熵,然后计算隧道的方法,并服从面积法在下一个领先的顺序在非对易参数$θ$。修正熵/面积定律,然后通过超越半经典近似。半经典熵/面积定律的主导修正被发现是对数的,其系数涉及非对易参数$θ$。

英文摘要:

We emphasize the importance of the Voros product in defining a noncommutative inspired Reissner-Nordström black hole. The entropy of this black hole is then computed in the tunneling approach and is shown to obey the area law at the next to leading order in the noncommutative parameter $θ$. Modifications to entropy/area law is then obtained by going beyond the semi-classical approximation. The leading correction to the semiclassical entropy/area law is found to be logarithmic and its coefficient involves the noncommutative parameter $θ$.
