论文摘要
我们研究具有时空不均匀性的强背背景电场中的电子峰值生产过程，在时间依赖性基础光量量化方法中。我们计算出可观察到的物质，例如不变质量和产生对的纵向动量分布作为进化时间的函数，并将真空衰减速率与schwinger效应进行比较。我们观察到背景场的临界强度，在此上面，真空衰减速率不再随时间定期振荡，而如扰动理论中。这项工作可能为研究成对生产过程的研究提供了基础，该过程具有逼真的时空结构。
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.
