摘要

真空波动在自发辐射中起着核心作用。最近有人提出，这些波动也可能是吸收动力学的基本因素，打破了线性量子演化固有的叠加。我们分析了这一提议与之前双自发辐射结果的一致性。此外，对于两个原子的单次吸收，我们提出了一种基于后续自发辐射模式时间依赖性的检验方法，可以通过实验解决这个问题。这种检验方法比建立在卡西米尔效应基础上的最初建议更为可行。我们的方法还可以比较真空波动作为分离机制和发射触发器的时间尺度。

Are vacuum fluctuations relevant in absorption dynamics?

Vacuum fluctuations play a central role in spontaneous emission. Recently, it has been suggested that these fluctuations could also be fundamental in the absorption dynamics, breaking the superposition inherent to the linear quantum evolution. We analyze the consistency of that proposal with previous results in double spontaneous emission. Moreover, for the case of single absorption by two atoms, we present a test based on the time dependence of the subsequent spontaneous emission patterns, which can experimentally settle the question. This test is more viable than the original proposal, built on the Casimir effect. Our approach also allows for the comparison between the time scales of vacuum fluctuations as a disentangling mechanism and an emission trigger.
