I On Feynamn Diagrams

  1. Nov 21, 2016 #1
    What I would have to study before reaching the subject treated by Feynamn Diagrams? Is it too beyond the subjects treated in books like Shankar, Mc Intyre, Griffiths, etc? (I'm sorry for my poor English.)

    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.
