Gauss-Bonnet膜世界中的广义热力学第二定律

Generalized second law of thermodynamics in Gauss-Bonnet braneworld

Ahmad Sheykhi, Bin Wang

摘要:

本文研究了广义热力学第二定律在一般膜世界模型中的有效性,分别在膜上和体中引入曲率修正项。利用导出的与视视界相关的熵表达式,我们研究了总熵的时间演化,包括视视界的导出熵和视视界内物质场的熵。我们表明,广义热力学第二定律是满足3-膜嵌入在5D时空曲率修正。

英文摘要:

We investigate the validity the generalized second law of thermodynamics in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. Employing the derived entropy expression associated with the apparent horizon, we examine the time evolution of the total entropy, including the derived entropy of the apparent horizon and the entropy of the matter fields inside the apparent horizon. We show that the generalized second law of thermodynamics is fulfilled on the 3-brane embedded in the 5D spacetime with curvature corrections.
