论文摘要
我们通过欧几里得动作方法研究了渐近型嵌入在等温腔中的高斯黑洞的热力学。我们考虑带电和未充电的黑洞,在扩展的相空间中工作,宇宙常数被视为热力学压力。我们通过它们的自由能检查了这些黑洞的相结构。在无偿的情况下,我们发现霍金页面和小型黑洞相变,其特征取决于高斯 - 骨网耦合的迹象。在带电的情况下,我们证明了swallowTube的存在,在发生小到大孔的黑洞过渡的相空间中向一个紧凑的区域发出信号。
We investigate the thermodynamics of Gauss-Bonnet black holes in asymptotically de Sitter spacetimes embedded in an isothermal cavity, via a Euclidean action approach. We consider both charged and uncharged black holes, working in the extended phase space where the cosmological constant is treated as a thermodynamic pressure. We examine the phase structure of these black holes through their free energy. In the uncharged case, we find both Hawking-Page and small-to-large black hole phase transitions, whose character depends on the sign of the Gauss-Bonnet coupling. In the charged case, we demonstrate the presence of a swallowtube, signaling a compact region in phase space where a small-to-large black hole transition occurs.
