摘要

我们研究了保形边界条件下宇宙常数消失的爱因斯坦引力热力学。我们的重点是将一系列亚广义项与热效应场理论的预测进行比较，我们发现在空间球体、双曲空间和平面空间上的边界理论与热效应场理论一致。我们计算了主要的威尔逊系数，并观察到对自由能的第一次亚广泛修正是负的。这违反了量子场论中该系数的推测界限，我们将其解释为引力在假定的边界对偶中没有完全解耦的信号。

Flat space gravity at finite cutoff

We study the thermodynamics of Einstein gravity with vanishing cosmological constant subjected to conformal boundary conditions. Our focus is on comparing the series of subextensive terms to predictions from thermal effective field theory, with which we find agreement for the boundary theory on a spatial sphere, hyperbolic space, and flat space. We calculate the leading Wilson coefficients and observe that the first subextensive correction to the free energy is negative. This violates a conjectured bound on this coefficient in quantum field theory, which we interpret as a signal that gravity does not fully decouple in the putative boundary dual.
