广义不确定原理下的黑洞热力学

Black hole thermodynamics with generalized uncertainty principle

Li Xiang, X. Q. Wen

摘要:

在标准观点中,静止黑洞的温度与其表面重力$T_H=\hbarκ/2π$成正比。这是一个半经典的结果,没有考虑量子引力效应。这封信探讨了广义不确定原理(GUP)意义下黑洞温度的统一表达式。我们的讨论涉及到对被黑洞吸收的粒子的启发式分析。除了一类静态球对称黑洞外,还考虑了一类轴对称Kerr-Newman黑洞.与现有文献不同的是,我们提出黑洞的不可约质量代表吸收过程的特征尺寸。在de Sitter时空中,利用Bousso的D-界讨论了余子的信息容量。

英文摘要:

In the standard viewpoint, the temperature of a stationary black hole is proportional to its surface gravity, $T_H=\hbarκ/2π$. This is a semiclassical result and the quantum gravity effects are not taken into consideration. This Letter explores a unified expression for the black hole temperature in the sense of a generalized uncertainty principle(GUP). Our discussion involves a heuristic analysis of a particle which is absorbed by the black hole. Besides a class of static and spherically symmetric black holes, an axially symmetric Kerr-Newman black hole is considered. Different from the existing literature, we suggest that the black hole's irreducible mass represent the characteristic size in the absorption process. The information capacity of a remnant is also discussed by Bousso's D-bound in de Sitter spacetime.
