论文摘要
在量化的田间形式上，使用Kramers-Henneberger统一转换作为Block-Nordsieck转换的半经典对应物，研究了激光场的存在下的低能散射过程中的纠缠动力学。对于此类系统，获得了用于量子散射过程的固定状态Schrodinger方程。然后，通过使用部分波分析，我们引入了包含高强度激光场的新形式的纠缠忠诚度。因此，热量子等离子体（包括等离子体和量子筛选效果）的有效潜力用于显示纠缠的保真度比与激光振幅，等离子体参数和弹性电子碰撞的DEBYE长度参数的函数。结果表明，激光束或游离电子振荡的振幅在系统纠缠的演变中起着重要作用。
The dynamics of entanglement during the low energy scattering processes in bipartite systems at the presence of a laser field is studied, using the Kramers-Henneberger unitary transformation as the semi classical counterpart of the Block-Nordsieck transformation, in the quantizied field formalism. The Stationary-state Schrodinger equation for quantum scattering process is obtained for such systems. Then, by using partial wave analysis, we introduce new form of entanglement fidelity containing high intense laser field. Therefore, the effective potential of hot quantum plasmas including plasmon and quantum screening effect is used to show entanglement fidelity ratio as a function of the laser amplitude, plasmon parameter and the Debye length parameter for elastic electron-ion collisions. It is shown that the amplitude of laser beam or free electron oscillation play important roles in the evolution of entanglement of the system.
