论文摘要
量子随机性对与线性极化的超强度激光脉冲相撞的超偏见电子束的动力学的影响理论上在准经典状态下进行了研究。通常，即使在激光脉冲的浮动力下，电子束的角度分布也对称地沿该状态的横向保持。在这里我们表明，当初始角差$δθ_i\ Lessim 10^{ - 6} a_0^2 $，$ a_0 $是归一化激光场振幅，电子束的不对称角分布，是由于量子的量化量子量的量子量，而产生了电子束的不对称角度分布。辐射反应形式分别描述辐射电子动力学。对各种激光和电子参数的不对称性是可靠的，为当前可用的激光和电子束提供了可检测到的光子发射量子随机性的性质的实验可检测的特征。
Impacts of quantum stochasticity on the dynamics of an ultra-relativistic electron beam head-on colliding with a linearly polarized ultra-intense laser pulse are theoretically investigated in a quasi-classical regime. Generally, the angular distribution of the electron beam keeps symmetrically in transverse directions in this regime, even under the ponderomotive force of the laser pulse. Here we show that when the initial angular divergence $Δθ_i \lesssim 10^{-6} a_0^2$ with $a_0$ being the normalized laser field amplitude, an asymmetric angular distribution of the electron beam arises due to the quantum stochasticity effect, via simulations employing Landau-Lifshitz, quantum-modified Landau-Lifshitz equations, and quantum stochastic radiation reaction form to describe the radiative electron dynamics respectively. The asymmetry is robust against a variety of laser and electron parameters, providing an experimentally detectable signature for the nature of quantum stochasticity of photon emission with laser and electron beams currently available.
