论文摘要
我们在重力理论中研究了黑洞力学的第二定律，其作用中具有较高的衍生术语。 Wall描述了一种定义熵的方法，该熵满足第二定律，以在固定黑洞周围的扰动中线性顺序。我们表明，可以将其扩展为定义一个满足扰动中二次秩序的第二定律的熵，但前提是人们在有效的野外理论意义上对较高的衍生术语进行处理。我们还解决了Wall's方法的一些杰出问题，特别是其规模的不变性及其与Iyer-Wald熵的关系。
We investigate the second law of black hole mechanics in gravitational theories with higher derivative terms in the action. Wall has described a method for defining an entropy that satisfies the second law to linear order in perturbations around a stationary black hole. We show that this can be extended to define an entropy that satisfies the second law to quadratic order in perturbations, provided that one treats the higher derivative terms in the sense of effective field theory. We also address some outstanding issues with Wall's method, in particular, its gauge invariance and its relation to the Iyer-Wald entropy.
