论文摘要
有两个超级现象的家族:依靠原子合奏或自由电子的相关发射。在这里,我们研究了由相干形的电子驱动的原子集合的发射。这种相互作用会产生从原子和电子连贯性中出现的超产物 - 发射强度在原子的数量和电子数量中均高度缩放。这种现象使电子可以成为物质中量子相关性的新型探针,具有高时空和空间分辨率。
There exist two families of superradiance phenomena: relying on correlated emission by an ensemble of atoms or by free electrons. Here we investigate emission from an ensemble of atoms driven by coherently shaped electrons. This interaction creates superradiance emerging from both the atoms' and the electrons' coherence - with emission intensity that scales quadratically in both the number of atoms and number of electrons. This phenomenon enables electrons to become novel probes of quantum correlations in matter, with high temporal and spatial resolution.
