Interacting observable and measurement in Quantum Field Theory

该项目的想法是将Fewster和Verch在他们的论文“量子场和局部测量”中提出的测量方案推广到具有任意相互作用的QFT模型中的可观测量。我们将从布赫霍尔茨和Fredenholz在论文“相互作用量子场论的C*-代数方法”中提出的框架开始。接下来，我们将发展微扰代数量子场论的推广，并将处理一些物理例子。

The idea of the project is to generalize the measurement scheme proposed by Fewster and Verch in their paper "Quantum fields and local measurements" to observables in QFT models with arbitrary interactions. We will start with the framework of Buchholz and Fredenhagen proposed in the paper "A C*-algebraic approach to interacting quantum field theories". Next, we will develop a generalization to perturbative algebraic quantum field theory and will treat some physical examples.
