论文摘要
加速辐射 - 或Unruh辐射 - 通过不断加速的观察者或检测器观察到的热辐射，尽管与Hawking Radiation具有相似之处，但到目前为止，在实验上观察到了极其挑战。最近的一个建议是，在存在镜子的情况下，原子在其基态下的恒定加速会激发原子，同时导致其在Unruh型过程中发出光子。在这项工作中，我们表明，仅通过简单的谐波运动来摇动原子就可以产生相同的效果。我们在一阶扰动理论中计算了此的过渡速率，并考虑在固定镜的存在下或在空腔内或仅在空真空中的原子的谐波运动。对于后者，我们提出了一个电路QED电位实现，该实现产生了$ \ sim 10^{ - 4} \，{\ rm Hz} $的过渡速率，可以在实验中检测到。
Acceleration radiation - or Unruh radiation - the thermal radiation observed by an ever accelerating observer or detector, although having similarities to Hawking radiation, so far has proved extremely challenging to observe experimentally. One recent suggestion is that, in the presence of a mirror, constant acceleration of an atom in its ground state can excite the atom while at the same time cause it to emit a photon in an Unruh-type process. In this work we show that merely by shaking the atom, in simple harmonic motion for example, can have the same effect. We calculate the transition rate for this in first order perturbation theory and consider harmonic motion of the atom in the presence of a stationary mirror, or within a cavity or just in empty vacuum. For the latter we propose a circuit-QED potential implementation that yields transition rates of $\sim 10^{-4}\,{\rm Hz}$, which may be detectable experimentally.
