论文摘要
我们研究了测试标量和电磁场在幻影虫洞的构型中扰动的时间演变，这些象征孔被深色能量包围，带有状态参数$ω<-1 $。我们观察到反映虫洞特性的回声的明显信号，并披露了这种现象背后的物理原因。特别是，我们发现状态的暗能量方程在波动扰动中的回波中具有明显的烙印。当$ω$从下方划分phantom $ω= -1 $时，回声的延迟时间会更长。在不久的将来可能会检测到引力波的回声，回声频谱中状态的暗能量方程的特征可以用作对黑能的局部测量。
We study the time evolution of the test scalar and electromagnetic fields perturbations in configurations of phantom wormholes surrounded by dark energy with state parameter $ω< -1$. We observe obvious signals of echoes reflecting wormholes properties and disclose the physical reasons behind such phenomena. In particular, we find that the dark energy equation of state has a clear imprint in echoes in wave perturbations. When $ω$ approaches the phantom divide $ω=-1$ from below, the delay time of echoes becomes longer. The echo of gravitational wave is likely to be detected in the near future, the signature of the dark energy equation of state in the echo spectrum can serve as a local measurement of the dark energy.
