论文摘要
QED级联反应在极端的天体物理环境（如磁铁）中起着重要作用。它们也可以通过通过强烈的激光场传递相对论电子束来产生它们。这些QED级联反应中的集体对等离子体效应的特征表明，通过激光频谱中的等离子体诱导的频率升缩表现出了精美的细节。 值得注意的是，即使在相对论速度移动的小等离子体体积中也可以检测到这些特征。因此，如果超密集的电子束与多PW激光器共裂，则可以用现有技术探索强场量子和集体对等离子体效应。
QED cascades play an important role in extreme astrophysical environments like magnetars. They can also be produced by passing a relativistic electron beam through an intense laser field. Signatures of collective pair plasma effects in these QED cascades are shown to appear, in exquisite detail, through plasma-induced frequency upshifts in the laser spectrum. Remarkably, these signatures can be detected even in small plasma volumes moving at relativistic speeds. Strong-field quantum and collective pair plasma effects can thus be explored with existing technology, provided that ultra-dense electron beams are colocated with multi-PW lasers.
