我们研究（变形）Horava-Lifshitz (H-L) 引力中的黑洞相变，包括带电/不带电拓扑黑洞和 KS 黑洞。稳定性分析和状态空间几何都被使用。我们在这些黑洞中发现了有趣的相结构，其中一些特性在爱因斯坦引力中从未观察到。特别是小半径H-L引力中黑洞的稳定性特性发生了巨大变化，这可以被认为是时空小尺度行为信息的泄漏。已经发现了热力学指标无法揭示的 H-L 引力中的新黑洞局域相变。在具有双曲事件视界的 H-L 引力中，带电黑洞的比热曲线存在无限不连续性。然而，这种不连续性不具有相应的热力学度量的曲率奇点。我们的结果可能为更好地理解 H-L 引力以及黑洞热力学提供新的见解。
We study black hole phase transitions in (deformed) Horava-Lifshitz (H-L) gravity, including the charged/uncharged topological black holes and KS black hole. Stability analysis and state space geometry are both used. We find interesting phase structures in these black holes, some of the properties are never observed in Einstein gravity. Particularly, the stability properties of black holes in H-L gravity with small radius change dramatically, which can be considered as a leak of information about the small scale behavior of spacetime. A new black hole local phase transition in H-L gravity which cannot be revealed by thermodynamical metrics has been found. There is an infinite discontinuity at the specific heat curve for charged black hole in H-L gravity with hyperbolic event horizon. However, this discontinuity does not have a corresponding curvature singularity of thermodynamical metrics. Our results may provide new insights towards a better understanding of the H-L gravity, as well as black hole thermodynamics.
