具有非最小导数耦合的一般标量-张量理论的热力学

Thermodynamics of general scalar-tensor theory with non-minimally derivative coupling

Yumei Huang, Yungui Gong

摘要:

利用通常的熵和视视界温度的定义,讨论了一般标量-张量引力理论中,在标量场与爱因斯坦张量非极小耦合的动力学项下,视视界热力学第一定律.通过引入一个与视视界上Misner-Sharp质量相等的类质量函数,证明了视视界上的热力学热力学第一定律与一般模型的Friedmann方程之间的等价性.结果进一步支持了热力学热力学第一定律与Friedmann方程之间的普适关系。

英文摘要:

With the usual definitions for the entropy and the temperature associated with the apparent horizon, we discuss the first law of the thermodynamics on the apparent in the general scalar-tensor theory of gravity with the kinetic term of the scalar field non-minimally coupling to Einstein tensor. We show the equivalence between the first law of thermodynamics on the apparent horizon and Friedmann equation for the general models, by using a mass-like function which is equal to the Misner-Sharp mass on the apparent horizon. The results further support the universal relationship between the first law of thermodynamics and Friedmann equation.
