Weak Energy Condition, Trapped Surfaces and Black hole Third Law

F. Bahmani, F. Shojai, Sh. Anjomshoaa

AI总结:

本文研究了4维和n维Vaidya黑洞家族的热力学第三定律,证明了表面引力与极值性定义的一致性,并探讨了非极值黑洞有限时间达极值与弱能量条件假设之间的潜在参数冲突。

摘要:

我们考虑了4维和n维Vaidya黑洞家族的热力学第三定律,其中包括许多受关注的情形。由于动态黑洞的表面引力定义以及极值性条件存在多个版本,我们首先证明对于所考虑的4维和n维Vaidya家族,这些定义彼此一致。我们首先假设非极值黑洞在有限时间后演化至极值状态,其次假设源的弱能量条件始终成立。然后我们比较了这些假设的结果,并研究是否存在这两个假设相互冲突的黑洞参数范围。

英文摘要:

We consider the third law of thermodynamics for families of 4- and n-dimensional Vaidya black holes, including many of interest. Since there are several versions of the definition of surface gravity as well as the extremality condition for dynamical black holes, we first show that for the considered 4- and n-dimensional Vaidya families, these definitions are consistent with each other. We assume, first, that a non-extremal black hole evolves to an extremality state after a finite time and second, that the weak energy condition for the source holds at all times. We then compare the results of these assumptions and investigate whether there are ranges of black hole parameters where these two assumptions are in conflict.
