论文摘要
众所周知，De Sitter（DS）黑洞通常具有黑洞的地平线和宇宙学的地平线，两者都有鹰的辐射。但是两个视野的辐射温度通常不同，因此DS黑洞不符合热平衡稳定性的要求，这给研究黑洞的热力学特征带来了一定的困难。在本文中，DS黑洞被视为热力学系统，并获得了系统的有效热力学量。讨论了各种状态参数对大量重力时空中有效热力学量的影响。给出了De Sitter Black Hole在大量重力时空中的相变的状况。我们认为，DS黑洞的总熵是两个视野的相应熵的总和，以及来自两个视野的相关性的额外项。通过比较黑洞地平线与宇宙学之间与Lennard-Jones力之间的相互作用的熵力，我们发现两个系统之间的熵力的变化规则令人惊讶地相同。这项研究将帮助我们探索加速宇宙扩展的真正原因。
It is well known that de Sitter(dS) black holes generally have a black hole horizon and a cosmological horizon, both of which have Hawking radiation. But the radiation temperature of the two horizons is generally different, so dS black holes do not meet the requirements of thermal equilibrium stability, which brings certain difficulties to the study of the thermodynamic characteristics of black holes. In this paper, dS black hole is regarded as a thermodynamic system, and the effective thermodynamic quantities of the system are obtained. The influence of various state parameters on the effective thermodynamic quantities in the massive gravity space-time is discussed. The condition of the phase transition of the de Sitter black hole in massive gravity space-time is given. We consider that the total entropy of the dS black hole is the sum of the corresponding entropy of the two horizons plus an extra term from the correlation of the two horizons. By comparing the entropic force of interaction between black hole horizon and the cosmological horizon with Lennard-Jones force between two particles, we find that the change rule of entropic force between the two system is surprisingly the same. The research will help us to explore the real reason of accelerating expansion of the universe.
