论文摘要
标量调节重力的新热力学用于在这类理论中的空间均质和各向同性宇宙学上，并在分析溶液上进行了测试。一个永远扩展的宇宙接近爱因斯坦的“平衡状态”，在后期的有效温度为零，并在时空奇异点附近偏离它。通过扩展和“加热”的“冷却”在大裂口附近竞争，在那里发现有效温度在共同耦合标量场的情况下有所不同。
A new thermodynamics of scalar-tensor gravity is applied to spatially homogeneous and isotropic cosmologies in this class of theories and tested on analytical solutions. A forever-expanding universe approaches the Einstein "state of equilibrium" with zero effective temperature at late times and departs from it near spacetime singularities. "Cooling" by expansion and "heating" by singularities compete near the Big Rip, where it is found that the effective temperature diverges in the case of a conformally coupled scalar field.
