论文摘要
受Steinhauer及其同事的最新实验的启发,我们提出了一个简单的模型,该模型描述了Bose-Einstein凝结物中声学黑洞的形成,从而可以在相应的密度密度相关器的时间内对演化的分析计算。我们显示了从地平线显着流离失所的“量子气氛”区域中的模拟鹰辐射的出现。在$ t = 0 $的情况下,在初始温度t的存在下进行了定量研究,就像实验中一样。
Inspired by a recent experiment by Steinhauer and co-workers, we present a simple model which describes the formation of an acoustic black hole in a Bose-Einstein condensate, allowing an analytical computation of the evolution in time of the corresponding density-density correlator. We show the emergence of analog Hawking radiation out of a "quantum atmosphere" region significantly displaced from the horizon. This is quantitatively studied both at $T=0$ and even in the presence of an initial temperature T, as is always the case experimentally.
