摘要:
我们分析了自由电子与由相同光学发射体组成的集体的相互作用。发射体之间的互相关性和相关性可以增强与每个电子的相互作用,并在其能谱上留下印记。我们提出了实现此类集体相互作用的方案。作为一种可能的应用,我们研究了自由电子与超辐射系统之间的相互作用,展示了电子如何探测超辐射的超快人口动态。
英文摘要:
We analyze the interaction between a free electron and an ensemble of identical optical emitters. The mutual coherence and correlations between the emitters can enhance the interaction with each electron and become imprinted on its energy spectrum. We present schemes by which such collective interactions can be realized. As a possible application, we investigate free-electron interactions with superradiant systems, showing how electrons can probe the ultrafast population dynamics of superradiance.
