Abstract

Stealth solutions of scalar-tensor gravity and less-known de Sitter spaces that generalize them are analyzed regarding their possible role as thermal equilibria at non-zero temperature in the new first-order thermodynamics of scalar-tensor gravity. No stable equilibria are found, further validating the special role of general relativity as an equilibrium state in the landscape of gravity theories, seen through the lens of first-order thermodynamics.

标量张量引力中隐身和德西特时空的热稳定性

分析了标量张量引力的隐身解和推广它们的鲜为人知的de Sitter空间在标量张量引力的新一阶热力学中的非零温度热平衡的可能作用。没有发现稳定的平衡态，这进一步验证了广义相对论作为一种平衡态在重力理论景观中的特殊作用，从一阶热力学的角度来看。
