论文摘要
我们通过空腔中的短距离排斥潜力发展了电子散射理论。在超筋电子与空腔电磁场的耦合方面，该磁场的真空波动导致了限制在排斥潜力核心的排序极性状态的动态稳定。当游离电子的能量与受封闭状态的能量重合时，出现了伴随着空腔光子发射的电子的极有效的共振非弹性散射。讨论了这种效果作为非经典光线可能的自由电子源的基础。
We developed a theory of electron scattering by a short-range repulsive potential in a cavity. In the regime of ultrastrong electron coupling to the cavity electromagnetic field, the vacuum fluctuations of the field result in the dynamical stabilization of a quasistationary polariton state confined in the core of the repulsive potential. When the energy of a free electron coincides with the energy of the confined state, the extremely efficient resonant nonelastic scattering of the electron accompanied by emission of a cavity photon appears. This effect is discussed as a basis for possible free-electron sources of nonclassical light.
