Feynman diagrams are essential tools in quantum field theory, serving as pictorial representations of terms in a perturbation series. To effectively utilize Feynman diagrams, a solid understanding of quantum field theory is necessary, which extends beyond the foundational concepts covered in introductory texts such as Shankar, McIntyre, and Griffiths. While Feynman diagrams can theoretically be applied in standard quantum mechanics, their practical use is predominantly within quantum field theory. Mastery of these diagrams requires a comprehensive grasp of perturbation theory and its applications.
PREREQUISITESStudents and researchers in theoretical physics, particularly those interested in quantum field theory and the application of Feynman diagrams in particle physics.
Thank you!Orodruin said:Feynman diagrams are pictorial representations of terms in a perturbation series. A priori, you could use them to solve any system perturbatively as long as perturbation theory holds. As such you could a priori use them in standard quantum mechanics, but this is rarely done.
In practice, what you are looking for is likely how to use Feynman diagrams in quantum field theory. This requires more background than your introductory quantum mechanics textbook.
