摘要
文中研究了量子化电磁场中非经典电子波包的运动。当初始光子态是Fock态时,随着电子和光子所组成系统的演化,初始可分离的电子态和光子态会互相纠缠,而且电子几率密度的时间演化呈非经典的分岔和汇合的现象。基到这些非经典特征,电子可以在光子场中被加速和减速,而系统保持能量守恒。
We study the nonclassical electronic wave packet in quantized electromagnetic Field. It is found that eletron and photons become entangled as the electronic wave packet evolves. Moreover, the time evolution of the probability density of the electron exhibits bifurcation and confluence. Based on these nonclassical features, eletron can be accelerated or decelerated by the light without violating the energy-momentum conservation.
