标题： Deep Connection Between Thermodynamics and Gravity in Gauss-Bonnet Braneworld

摘要： 我们揭示了在具有膜上和体中曲率修正项的一般膜宇宙模型中，热力学与引力之间的深刻联系。 我们表明嵌入在具有曲率修正项的五维时空中的三维膜上的弗里德曼方程可以直接写成视界上的热力学第一定律形式。 利用热力学第一定律，我们提取了膜上视界的熵表达式，这在研究高斯-博内重力中膜上黑洞视界的热力学性质时是有用的。 显示英文摘要

摘要： We disclose the deep connection between the thermodynamics and gravity in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. We show that the Friedmann equations on the 3-brane embedded in the 5D spacetime with curvature correction terms can be written directly in the form of the first law of thermodynamics on the apparent horizon. Using the first law, we extract the entropy expression of the apparent horizon on the brane, which is useful in studying the thermodynamical properties of the black hole horizon on the brane in Gauss-Bonnet gravity.
