论文摘要
标量场理论的功能重归其化群流具有四个维的Minkowski时空，并通过保持IR和UV粒子模式的纠缠，以四维的Minkowski时空进行了标量场理论的功能性重归其化。有人认为，必须在由截止的帮助下定义的量子场理论中考虑开放的交互通道，并且在封闭或几乎封闭的模型中发现了非扰动的UV-IR纠缠。
The functional renormalization group flow of a scalar field theory with quartic couplings and a sharp spatial momentum cutoff is presented in four-dimensional Minkowski space-time for the bare action by retaining the entanglement of the IR and the UV particle modes. It is argued that the open interaction channels have to be taken into account in quantum field theory defined by the help of a cutoff, and a non-perturbative UV-IR entanglement is found in closed or almost closed models.
