摘要:

利用线性化理论研究了辐射反应对电子在对向传播圆偏振激光束中动力学的影响,所得结果与数值解吻合较好。首次用线性稳定性理论分析了电子相空间中不动点的性质,指出如果考虑经典辐射反应,中心节点将成为吸引子。电子动力学的显着影响的性质的不动点和电子相空间密度被发现是指数增加附近的吸引子。密度增长率的理论推导和粒子模拟进一步验证,这可以在实验中检测到定性探索辐射反应的影响。该吸引子还可以通过调节碰撞激光频率来实现一系列纳米尺度的飞行电子切片。

英文摘要:

The radiation reaction effects on electron dynamics in counter-propagating circularly polarized laser beams are investigated through the linearization theorem and the results are in great agreement with numeric solutions. For the first time, the properties of fixed points in electron phase-space were analyzed with linear stability theory, showing that center nodes will become attractors if the classical radiation reaction is considered. Electron dynamics are significantly affected by the properties of the fixed points and the electron phase-space densities are found to be increasing exponentially near the attractors. The density growth rates are derived theoretically and further verified by particle-in-cell simulations, which can be detected in experiments to explore the effects of radiation reaction qualitatively. The attractor can also facilitate to realize a series of nanometer-scaled flying electron slices via adjusting the colliding laser frequencies.
