强电场中的电子对产生

Pair production in strong electric fields

Zhiyu Lei, Bolun Hu, Xingbo Zhao

摘要:

本文采用含时基波前量子化方法研究了强背景电场中时空不均匀性下电子-正电子对的产生过程。我们计算的观测量,如不变的质量和纵向动量分布的产生对作为演化时间的函数,并比较真空衰变率的Schwinger效应。我们观察到一个临界强度的背景场,真空衰减率不再是随时间周期性振荡的微扰理论。这一工作为研究具有真实时空结构的强场中的电子对产生过程提供了基础。

英文摘要:

We study the electron-positron pair production process in strong background electric fields with spatio-temporal inhomogeneity in the time-dependent Basis Light-front Quantization approach. We calculate the observables such as the invariant mass and the longitudinal momentum distribution of the produced pairs as functions of evolution time and compare the vacuum decay rate with that of the Schwinger effect. We observe a critical intensity of background field, above which the vacuum decay rate is no longer oscillating with time periodically as in perturbation theory. This work may provide the foundation for the study of the pair production process in strong fields with realistic spacetime structures.
