Schwarzschild黑洞的Poincare递归

Poincare recurrences of Schwarzschild black holes

George Siopsis

摘要:

讨论了Schwarzschild黑洞的大质量标量扰动。我们认为量子效应改变了视界附近的有效势,导致格林函数中的庞加莱递归。在半经典水平的结果是独立的细节修改的潜力提供其最小值附近的地平线是成反比的庞加莱时间的平方。这种修改可以被视为近地平线几何形状的变化。我们认为明确的例子,砖墙,一个光滑的截止和一个虫洞般的修改表明,他们都导致相同的结果在领先的顺序。

英文摘要:

We discuss massive scalar perturbations of a Schwarzschild black hole. We argue that quantum effects alter the effective potential near the horizon resulting in Poincare recurrences in Green functions. Results at the semi-classical level are independent of the details of the modification of the potential provided its minimum near the horizon is inversely proportional to the square of the Poincare time. This modification may be viewed as a change in the near-horizon geometry. We consider explicitly the examples of a brick wall, a smooth cutoff and a wormhole-like modification showing that they all lead to the same results at leading order.
