我们提出了在表观视界上构建热力学第一定律的一般程序,并通过在一些扩展的引力理论中检验它来说明其有效性。应用这个过程,我们可以描述嵌入在一个不平凡的块体中的兰德尔-桑德鲁姆膜世界中表观地平线的热力学。我们讨论了用于将弗里德曼方程与热力学第一定律联系起来的类质量函数,并获得了其特殊情况,给出了洛夫洛克引力中的广义米斯纳-夏普质量。
We present a general procedure to construct the first law of thermodynamics on the apparent horizon and illustrate its validity by examining it in some extended gravity theories. Applying this procedure, we can describe the thermodynamics on the apparent horizon in Randall–Sundrum braneworld imbedded in a nontrivial bulk. We discuss the mass-like function which was used to link Friedmann equation to the first law of thermodynamics and obtain its special case which gives the generalized Misner–Sharp mass in Lovelock gravity.
