论文摘要
通过采用计算量子场理论方法，研究了控制场对能量光谱以及创建对的数量以及通过狄拉克真空模式传递的信息的影响。发现能量光谱上的振荡结构对控制场的方向，宽度和振荡频率敏感。对频率很小，频率很高，这对产量可能会发生明显的变化。此外，在控制场中编码的信息，例如场方向，激光频率和两个激光脉冲之间的时间间隔，也可以由真空模式体现在随时间变化时真空模式。这些结果不仅可以加深我们对配对创建和信息传输的控制的理解，而且还可以对将来相关实验的理论参考。
The effects of control fields on the energy spectra and the number of created pairs and the information transmission by the Dirac vacuum modes are investigated by employing computational quantum field theory approach. It is found that the oscillation structures on the energy spectra are sensitive to the direction, the width, and the oscillation frequency of control fields. The pair yield can have obvious changes for a small frequency and a very large frequency. Moreover, the information encoded in the control fields, such as the field direction, the laser frequency and the time interval between two laser pulses, can also embodied by the vacuum modes in the change of pair-creation rate with time. These results not only can deepen our understanding of the control of pair creation and the information transmission, but also can provide a theoretical reference to the related experiments in the future.
