论文摘要

在三维保安中,不存在经典黑洞,而Schwarzschild-de Sitter解决方案则描述了带有单个宇宙学视野的锥形缺陷。我们认为,共形场的量子反射可以产生黑洞的地平线,从而导致三维量子de Sitter黑洞。它的大小可能与宇宙学范围一样大。我们明确地展示了这些溶液是如何使用Braneworld全息图出现的,但也与由于圆锥形的圆锥形de Sitter空间中的合并耦合标量场引起的非全外,扰动分析进行了比较。我们分析了这个量子黑洞的热力学,表明它的行为与其经典的四维对应物相似,在那里,广义熵取代了经典的Bekenstein-Hawking熵。我们计算熵缺陷是由于将三维黑洞和重新访问的参数成核,以便对DS空位进行矩阵模型描述。最后,我们对从Braneworld的角度看出的DS空间的全息二重要说明发表评论。

In three-dimensional de Sitter space classical black holes do not exist, and the Schwarzschild-de Sitter solution instead describes a conical defect with a single cosmological horizon. We argue that the quantum backreaction of conformal fields can generate a black hole horizon, leading to a three-dimensional quantum de Sitter black hole. Its size can be as large as the cosmological horizon in a Nariai-type limit. We show explicitly how these solutions arise using braneworld holography, but also compare to a non-holographic, perturbative analysis of backreaction due to conformally coupled scalar fields in conical de Sitter space. We analyze the thermodynamics of this quantum black hole, revealing it behaves similarly to its classical four-dimensional counterpart, where the generalized entropy replaces the classical Bekenstein-Hawking entropy. We compute entropy deficits due to nucleating the three-dimensional black hole and revisit arguments for a possible matrix model description of dS spacetimes. Finally, we comment on the holographic dual description for dS spacetimes as seen from the braneworld perspective.
