论文摘要
我们提出了对量子振荡器的近距离行为的量子光学处理，将量子振荡器自由垂直到现有的Schwarzschild黑洞中。我们使用Painleve Gullstrand坐标来定义全球真空状态。与Minkowski真空中的加速振荡器相反，在初始瞬态之外没有辐射的振荡器，我们发现振荡器在试图与环境真空中均衡时，振荡器辐射到无穷大的正能量到无穷大，而负能量则辐射到黑洞中。我们讨论模型与霍金辐射的关系。
We present a quantum optics treatment of the near horizon behaviour of a quantum oscillator freely-falling into a pre-existing Schwarzschild black hole. We use Painleve-Gullstrand coordinates to define a global vacuum state. In contrast to an accelerated oscillator in the Minkowski vacuum, where there is no radiation beyond an initial transient, we find that the oscillator radiates positive energy to to infinity and negative energy into the black hole as it attempts to come into equilibrium with the ambient vacuum. We discuss the relationship of the model to Hawking radiation.
