黑洞热力学与大质量引力

Black Hole Thermodynamics and Massive Gravity

Fabio Capela, Peter G. Tinyakov

摘要:

本文研究了大质量引力中的广义热力学热力学定律。利用显式黑洞解,我们设计了黑洞合并过程,其中i)系统的总熵减小ii)零温度极值黑洞产生.因此,热力学第二和第三热力学定律都被违反了。在这两种情况下,违背都可以追溯到负质量黑洞的存在,而负质量黑洞又与零能量条件的违背有关。热力学第三定律的违反意味着,特别是,裸奇点可能会作为无奇点状态演化的结果而产生。这可能表明模型中存在问题,除非可以动态禁止从正质量态产生负质量黑洞,或者裸奇点可以在完整的量子理论中以某种方式得到解决。

英文摘要:

We consider the generalized laws of thermodynamics in massive gravity. Making use of explicit black hole solutions, we devise black hole merger processes in which i) total entropy of the system decreases ii) the zero-temperature extremal black hole is created. Thus, both second and third laws of thermodynamics are violated. In both cases, the violation can be traced back to the presence of negative-mass black holes, which, in turn, is related to the violation of the null energy condition. The violation of the third law of thermodynamics implies, in particular, that a naked singularity may be created as a result of the evolution of a singularity-free state. This may signal a problem in the model, unless the creation of the negative-mass black holes from positive-mass states can be forbidden dynamically or the naked singularity may somehow be resolved in a full quantum theory.
