标题： Analogue black holes and scalar-dilaton theory

摘要： 本注释分析了一维空间中两个视界类比黑洞系统的长波长动力学。 通过引入一个有效标量-膨胀子模型，我们表明可以得到时间相关的霍金通量和霍金辐射的能量密度的闭合表达式。 我们表明，在没有超光速模式的情况下，存在真空不稳定性。 这种不稳定性对于相对论者来说，可识别为由于真空极化导致黑洞柯西视界不稳定性的类比。 显示英文摘要

摘要： This note analyses on the long wavelength dynamics of a two horizon analogue black hole system in one spatial dimension. By introducing an effective scalar-dilaton model we show that closed form expressions can be obtained for the time-dependent Hawking flux and the energy density of the Hawking radiation. We show that, in the absence superluminal modes, there is a vacuum instability. This instability is recognisable to relativists as the analogue to the destabilisation of the Cauchy horizon of a black hole due to vacuum polarization.
