檢視所有 Wikipediahttps://en.wikipedia.org/wiki/Quantum_field_theoryIn theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of … 查看更多內容

https://zh.wikipedia.org/wiki/量子场论在理論物理學裡，量子場論（英語：Quantum field theory，簡稱：QFT）是結合了量子力學、狹義相對論和經典場論的一套自洽的概念和工具。 在粒子物理學和凝聚態物理學中，量子場論可以分別為亞原子粒子和準粒子建立量子力學模型。量子場論將粒子視為更基礎的場上的激發態，即所謂的量子，而粒子之間的交互作用則是以相應的場之間的交互項來描述。每個交互作用都可以用費曼圖來表示，這些圖不但是一種直觀視化的方法，而且還是相對論性協變微擾理論中用於計算粒子 …

- Quantum field theory originated in the 1920s from the problem of creating a quantum mechanical theory of the electromagnetic field. In particular, de Brogliein 1924 introduced the idea of a wave description of elementary systems in the following way: "we proceed in this work from the assumption of the existence of a certain periodic phenomenon of a...
