论文摘要
我们描述了两个不同但同等的半经典观点，即对等效原理和统一性都可以容纳。在一个中，单位性是内置的，而黑洞的内部仅作为一种涉及地平线（甚至可能是其他）自由度的集体现象有效地出现。在另一种更广泛的研究方法中，内部的存在是显现的，而基础动力学的单位性只能通过纳入某些重力的非驾驶效应来间接捕获。这两个图片分别对应于遥远的描述和基于纠缠岛/复制虫孔的描述。我们还基于以前的方法对De Sitter时空的全息描述进行了描述，在该方法中，全息理论位于静态斑块的伸展视野上。我们认为，这两种方法的存在源于量子力学的两种表述：规范和路径的整体形式主义。
We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective phenomenon involving horizon (and possibly other) degrees of freedom. In the other, more widely studied approach, the existence of the interior is manifest, while the unitarity of the underlying dynamics can be captured only indirectly by incorporating certain nonperturbative effects of gravity. These two pictures correspond to a distant description and the description based on entanglement islands/replica wormholes, respectively. We also present a holographic description of de Sitter spacetime based on the former approach, in which the holographic theory is located on the stretched horizon of a static patch. We argue that the existence of these two approaches is rooted in the two formulations of quantum mechanics: the canonical and path integral formalisms.
