摘要:

在最简单的全息轴子模型,即四维爱因斯坦-麦克斯韦-轴子理论中,构造了两个具有不寻常视界形状的新的拓扑黑洞精确解。我们在多种情形下绘制嵌入图,以展示这些新黑洞的不寻常形状。为了从准局域角度理解其热力学,我们从爱因斯坦方程重新推导了时空作为扭曲乘积 $\M2 \times \Mco2$ 的统一第一定律和 Misner-Sharp 质量。子流形 $\Mco2$ 的 Ricci 标量 $\Rhat$ 可以是非常数。我们进一步改进了基于统一第一定律的热力学方法。这种方法简化了解的构造,并暗示了向更高维度的推广。此外,我们应用统一第一定律来讨论黑洞热力学。

英文摘要:

Two novel topological black hole exact solutions with unusual shapes of horizons in the simplest holographic axions model, the four-dimensional Einstein-Maxwell-axions theory, are constructed. We draw embedding diagrams in various situations to display unusual shapes of novel black holes. To understand their thermodynamics from the quasi-local aspect, we re-derive the unified first law and the Misner-Sharp mass from the Einstein equations for the spacetime as a warped product $\M2 \times \Mco2$. The Ricci scalar $\Rhat$ of the sub-manifold $\Mco2$ can be a non-constant. We further improve the thermodynamics method based on the unified first law. Such a method simplifies constructing solutions and hints at generalization to higher dimensions. Moreover, we apply the unified first law to discuss black hole thermodynamics.
