Description
We generalize the main result of 1 to Lovelock theory. We find there exists sphere saddle metrics for a partition function at a fixed spatial volume in Lovelock theory. Those stationary points take exactly the same forms as in 1. The logarithm of $Z$ corresponding to a zero effective cosmological constant indicates the Bakenstein-Hawking entropy of the boundary area and the one corresponding to a positive effective cosmological constant points to the Wald entropy of the boundary area. We also find zeroth order phase transitions between different vacua.https://arxiv.org/abs/2212.10607
