In this work we present a large-deviation analysis for the counting statistics of atomic spontaneous emissions continuously detected in finite-bandwidth non-Markovian environment. We show that the statistics of the spontaneous emissions depends on the time interval (τ) of successive detections, which can result in big differences such as dynamical phase transition. This feature excludes the idea of regarding the spontaneous emissions as detection-free objective events. Possible experiment is briefly discussed in connection with the state-of-the-art optical cavity set-up.
在这项工作中，我们对在有限带宽非马尔可夫环境中连续检测到的原子自发发射的计数统计进行了大偏差分析。我们表明，自发发射的统计取决于连续检测的时间间隔（τ），这可能导致像动态相变这样的巨大差异。这一特征排除了将自发发射视为无检测的客观事件的想法。结合最新的光学腔装置，简要讨论了可能的实验。
