论文摘要
我们提出了这样一种观念,即重生化,低能物理学的重粒子效应以及有效场理论的构建与相互作用的量子场理论的不同模式的动量空间纠缠密切相关。使用统一转换将这些模式在扰动层面上解脱出来,我们在具有光和重场的标量场理论模型中显示,如何始终实现重新归一化以及如何构建低能效能场理论。我们还在此框架中获得了重新归一化组方程,并将其应用于标量字段理论模型。
We develop the idea that renormalization, decoupling of heavy particle effects from low energy physics and the construction of effective field theories are intimately linked to the momentum space entanglement of disparate modes of an interacting quantum field theory. Using unitary transformations to decouple these modes at the perturbative level, we show in a scalar field theoretical model with light and heavy fields, how renormalization may be consistently implemented and how the low energy effective field theory can be constructed. We also obtain a renormalization group equation in this framework and apply it to the scalar field theoretical model.
