论文摘要
我们介绍了一个具有状态依赖性恒定曲率的2D Dilaton重力模型的家庭，因此DS $ _2 $作为ADS $ _2 $的激发而出现。奇怪的是，强耦合区域以几何形式对应于渐近区域。除了这些主要差异外，许多功能类似于Almheiri-Polchinski模型。我们讨论了扰动和非扰动热力学稳定性，通过物质冲击波和半经典反应效应的气泡成核。在其中一些模型中，我们发现低温由广告$ _2 $主导，但高温主要由DS $ _2 $主导，这与Susskind的最新提案同时发生。
We introduce a family of 2D dilaton gravity models with state-dependent constant curvature so that dS$_2$ emerges as an excitation of AdS$_2$. Curiously, the strong coupling region corresponds to the asymptotic region geometrically. Apart from these key differences, many features resemble the Almheiri--Polchinski model. We discuss perturbative and non-perturbative thermodynamical stability, bubble nucleation through matter shockwaves, and semiclassical backreaction effects. In some of these models, we find that low temperatures are dominated by AdS$_2$ but high temperatures are dominated by dS$_2$, concurrent with a recent proposal by Susskind.
