“Path Integrals”

In the past two weeks, we developed basic QFT through canonical quantization. Now, using this work as motivation, we will redo our work using a more elegant (but even less rigorous) approach called the path integral. Starting from the Lagrangian for a field theory, we will examine its associated Dyson series and Feynman diagrams, and learn why even five year olds can use the Feynman rules to compute propagation amplitudes in interacting QFTs. One such interacting QFT we will draw examples from is quantum electrodynamics.
