摘要:

本文给出了超高强度圆极化场中慢电子引发的电子-正电子-光子级联的蒙特卡罗模拟结果,并对结果进行了讨论。我们的结果证实了先前的定性估计[A.M. Fedotov等人,PRL 105,080402(2010)]瀑布的形成。这种级联现象揭示了光场对电子和正电子的加速所导致的能量和动力学量子参数恢复的新性质,并可能成为超高强度激光与物质相互作用的主要特征。我们的方法包括辐射摩擦作用于单个电子和正电子。

英文摘要:

The results of Monte-Carlo simulations of electron-positron-photon cascades initiated by slow electrons in circularly polarized fields of ultra-high strength are presented and discussed. Our results confirm previous qualitative estimations [A.M. Fedotov, et al., PRL 105, 080402 (2010)] of the formation of cascades. This sort of cascades has revealed the new property of the restoration of energy and dynamical quantum parameter due to the acceleration of electrons and positrons by the field and may become a dominating feature of laser-matter interactions at ultra-high intensities. Our approach incorporates radiation friction acting on individual electrons and positrons.
