因果集黑洞

A Causal Set Black Hole

Song He, David Rideout

摘要:

我们明确计算史瓦西黑洞时空的因果结构,通过提供一个算法来决定是否有任何一对事件是因果相关的。这项研究的主要动机来自离散量子引力,特别是因果集方法,其中基本变量可以被认为是时空中随机选择事件的因果排序。这项工作开辟了一条道路,模拟非共形平坦时空的因果集的方法,这可能会允许一个研究的重要问题,如黑洞熵和霍金辐射的一个完整的四维因果集黑洞。

英文摘要:

We explicitly compute the causal structure of the Schwarzschild black hole spacetime, by providing an algorithm to decide if any pair of events is causally related. The primary motivation for this study comes from discrete quantum gravity, in particular the causal set approach, in which the fundamental variables can be thought of as the causal ordering of randomly selected events in spacetime. This work opens the way to simulating non-conformally flat spacetimes within the causal set approach, which may allow one to study important questions such as black hole entropy and Hawking radiation on a full four dimensional causal set black hole.
