五维空间中新的拓扑Gauss-Bonnet黑洞

New Topological Gauss-Bonnet Black Holes in Five Dimensions

Yuxuan Peng

摘要:

研究了具有负宇宙学常数的五维Einstein-Gauss-Bonnet引力的真空静态黑洞解。这些解具有非平凡拓扑的视界。第一种模型具有拓扑结构为$S^1 \times H^2$的视界和变化的Gauss-Bonnet耦合常数$α$。通过对其热力学性质的研究,发现其定容比热容为负值,是热力学不稳定的。第二种是以所谓的“溶胶流形”作为视界,有趣的是,高斯-博内耦合常数$α$和宇宙学常数$Λ$的乘积是固定的。对于第二个解,总能量和熵为零。这些结果扩大了我们对高维拓扑黑洞和引力理论的高曲率修正性质的认识。

英文摘要:

We investigate vacuum static black hole solutions of Einstein-Gauss-Bonnet gravity with a negative cosmological constant in five dimensions. These are solutions with horizons of nontrivial topologies. The first one possesses a horizon with the topology $S^1 \times H^2$, and a varying Gauss-Bonnet coupling constant $α$. By looking into its thermodynamic properties, we find that its specific heat capacity with fixed volume is negative, therefore it is thermodynamically unstable. The second one is equipped with a so-called "Sol-manifold" as its horizon, and interestingly, the product of the Gauss-Bonnet coupling constant $α$ and the cosmological constant $Λ$ is fixed. For the second solution, the total energy and entropy vanish. These results enlarge our knowledge of both topological black holes in higher dimensions and the property of higher curvature corrections of gravitational theories.
