Schwarzschild黑洞背景中的幻影标量扰动的波动力学

Wave dynamics of phantom scalar perturbation in the background of Schwarzschild black hole

Songbai Chen, Jiliang Jing, Qiyuan Pan

摘要:

利用Leaver连分式和时域方法研究了Schwarzschild黑洞背景下的幻影标量扰动的波动动力学。我们发现,负动能项的存在修改了标准结果的拟正规谱和后期的标量扰动的行为。后期演化中的幻影标量扰动将以指数速率增长。

英文摘要:

Using Leaver's continue fraction and time domain method, we investigate the wave dynamics of phantom scalar perturbation in the background of Schwarzschild black hole. We find that the presence of the negative kinetic energy terms modifies the standard results in quasinormal spectrums and late-time behaviors of the scalar perturbations. The phantom scalar perturbation in the late-time evolution will grow with an exponential rate.
