当基态原子被加速并且与之相互作用的场处于正常真空状态时，原子探测到安鲁辐射。我们表明，落入黑洞的原子发出加速辐射，在适当的初始条件下（布尔韦尔真空），其能谱看起来很像霍金辐射。这一分析也为爱因斯坦的加速度和引力等效原理提供了洞见。对于经历均匀加速的系统，也可以通过使用两点热相关函数的Kubo-Martin-Schwinger （KMS）周期性来获得Unruh温度；与本文中的大部分材料一样，这个已知的结果是通过扭曲获得的。
When ground-state atoms are accelerated and the field with which they interact is in its normal vacuum state, the atoms detect Unruh radiation. We show that atoms falling into a black hole emit acceleration radiation which, under appropriate initial conditions (Boulware vacuum), has an energy spectrum which looks much like Hawking radiation. This analysis also provides insight into the Einstein principle of equivalence between acceleration and gravity. The Unruh temperature can also be obtained by using the Kubo-Martin-Schwinger (KMS) periodicity of the two-point thermal correlation function, for a system undergoing uniform acceleration; as with much of the material in this paper, this known result is obtained with a twist.
