关于黑洞内部的Papadodimas-Raju方案
Aspects of the Papadodimas-Raju Proposal for the Black Hole Interior
摘要：
在这篇文章中，我详细介绍了Papadodimas和Raju最近提出的一个建议的一些特点，该建议是关于在纯态下单面AdS黑洞内部的CFT描述。我澄清了1/N修正的处理，并解释了该建议如何能够避免一些破坏其他最近的想法的陷阱。然而，我认为这个提议有一个令人不舒服的性质，即CFT希尔伯特空间中的状态没有明确的物理解释，这与普通的量子力学不同。我还将该建议的“状态依赖性”与更熟悉的现象进行了对比，认为与量子力学不同，在类似PR建议或其早期表现形式中的测量过程（包括仪器）不能用幺正演化来描述。这些问题使该提案有些模糊，似乎需要新的想法才能使其发挥作用。最后，我对量子力学应该在多大程度上适用于一个下落观察者的经验作了一些简短的推测。
英文摘要：
In this note I elaborate on some features of a recent proposal of Papadodimas and Raju for a CFT description of the interior of a one-sided AdS black hole in a pure state. I clarify the treatment of 1/N corrections, and explain how the proposal is able to avoid some of the pitfalls that have disrupted other recent ideas. I argue however that the proposal has the uncomfortable property that states in the CFT Hilbert space do not have definite physical interpretations, unlike in ordinary quantum mechanics. I also contrast the "state-dependence" of the proposal with more familiar phenomena, arguing that, unlike in quantum mechanics, the measurement process (including the apparatus) in something like the PR proposal or its earlier manifestations cannot be described by unitary evolution. These issues render the proposal somewhat ambiguous, and it seems new ideas would be needed to make some version of it work. I close with some brief speculation on to what extent quantum mechanics should hold for the experience of an infalling observer.
