论文摘要
在计算量子场理论的框架中研究了频率调制索特电势井中的电子峰值对生产。在具有静态空该电位井和频率调制振荡的组合潜在井中，调制振幅对创建对的数量具有很大的影响。获得了不同中心频率下频率的最佳调制幅度，这在大约两次时增加了电子数量。但是，对于通过频率调制的单个振荡电势井，CHIRP效应对中心频率敏感，并且在低中心频率方面，即使在四个数量级上，电子的数量也可以增加。这意味着，对于缓慢振荡的索特电位很好，通过频率调制的CHIRP效应比添加静态电势更好地改善了这对生产。
Electron-positron pair production in frequency modulated Sauter potential wells is investigated in the framework of the computational quantum field theory. In combined potential wells with a static Sauter potential well and a frequency modulated oscillating one, the modulated amplitude has a large effect on the number of created pairs. The optimal modulation amplitude of frequency at different center frequencies is obtained, which increases the number of electrons at about two times. However, for a single oscillating potential well with frequency modulation, chirp effect is sensitive to the center frequency, and the number of electrons can be enhanced even to four orders of magnitude at a regime of low center frequency. It implies that for a slowly oscillating Sauter potential well, the chirp effect through the frequency modulation is better than adding a static potential well to improve the pair production.
