大质量模和波动的霍金辐射

Hawking radiation of massive modes and undulations

Antonin Coutant, Alessandro Fabbri, Renaud Parentani, Roberto Balbinot, Paul Anderson

摘要:

我们计算了模的模拟霍金辐射,模的波矢垂直于视界。对于低频率,产生的质量项引起全反射。这产生了一个额外的模式混合,发生在超音速区域,这抵消了近地平线光谱的红外发散。因此,白洞流中发射的波动(0-频率波与宏观振幅)的振幅现在在线性水平上饱和,这与最近在无质量情况下发现的不同。此外,我们指出,质量引入了一种新的类型的波动,这是产生于黑洞流,这是很好地描述在流体动力学制度。

英文摘要:

We compute the analogue Hawking radiation for modes which posses a small wave vector perpendicular to the horizon. For low frequencies, the resulting mass term induces a total reflection. This generates an extra mode mixing that occurs in the supersonic region, which cancels out the infrared divergence of the near horizon spectrum. As a result, the amplitude of the undulation (0-frequency wave with macroscopic amplitude) emitted in white hole flows now saturates at the linear level, unlike what was recently found in the massless case. In addition, we point out that the mass introduces a new type of undulation which is produced in black hole flows, and which is well described in the hydrodynamical regime.
