我们规定了一个配方的粒子生产与实时随机量子化。为了构造延迟和时间有序传播子,我们将随机变量分解为正能量和负能量部分。在这种方式中,我们演示了如何推导出一个标准的施温格机制下随时间变化的电场公式。我们讨论了映射到Schwinger-Keldysh形式主义和经典的统计模拟的关系。
We prescribe a formulation of the particle production with real-time Stochastic Quantization. To construct the retarded and the time-ordered propagators we decompose the stochastic variables into positive- and negative-energy parts. In this way we demonstrate how to derive a standard formula for the Schwinger mechanism under time-dependent electric fields. We discuss a mapping to the Schwinger–Keldysh formalism and a relation to the classical statistical simulation.
