On the Quantum Kinetic Approach and the Scattering Approach to Vacuum Pair Production

Cesim K. Dumlu

摘要:

对于背景电场仅随时间变化的Schwinger对的产生,基于量子Vlasov方程的量子动力学方法和量子力学散射方法是完全等价的。这种不同的角度对量子动力学的方法,提出了新的近似方法,这是测试的详细使用可溶性脉冲状场配置,并可能提供有用的洞察力推广到更一般的电场,在1维以上的变化。

英文摘要:

For Schwinger pair production with background electric fields varying only in time, it is shown that the quantum kinetic approach, based on the quantum Vlasov equation, and the quantum mechanical scattering approach, are completely equivalent. This different perspective on the quantum kinetic approach suggests new approximation methods, which are tested in detail using a soluble pulse-like field configuration, and may give useful insight for generalization to more general electric fields, varying in more than 1 dimension.
