论文摘要
在最近的一系列著作中，已经探索了引力量化的引力边界及其在重力量化和黑洞信息方面的相关性。在这项工作中，我们通过敏锐地关注自由度作为黑洞熵的起源来进一步进一步。仔细检查了瓦尔德的熵公式，以及瓦尔德公式正确捕获黑洞的熵的原因。之后，讨论了Wald方法的局限性；提出了基于边界动力学的熵的连贯视图。解决了全息和瓦尔德熵之间的文献中观察到的差异。我们将熵定义概括为处理时间依赖的黑洞。大型对称性起着关键作用。 Coleman-de Luccia Bounce溶液的非二核边界条件和重力类似物是识别微骨和区分与不同类别溶液相关的熵的起源的核心。当前工作的结果导致了一种观点，即黑洞熵是热力学设置中的纠缠熵。
In a series of recent works the relevance of gravitational boundary degrees of freedom and their dynamics in gravity quantization and black hole information has been explored. In this work we further the progress by keenly focusing on the boundary degrees of freedom as the origin of black hole entropy. Wald's entropy formula is scrutinized, and the reason that the Wald's formula correctly captures the entropy of a black hole is examined. Afterwards, limitations of the Wald's method are discussed; a coherent view of entropy based on boundary dynamics is presented. The discrepancy observed in the literature between holographic and Wald's entropies is addressed. We generalize the entropy definition so as to handle a time-dependent black hole. Large gauge symmetry plays a pivotal role. Non-Dirichlet boundary conditions and gravitational analogues of Coleman-De Luccia bounce solutions are central in identifying the microstates and differentiating the origins of entropies associated with different classes of solutions. The result in the present work leads to a view that black hole entropy is entanglement entropy in a thermodynamic setup.
