Perturbation Theory in Quantum Mechanics (Practice)
Example of using perturbation theory: the case of the infinite square well with a delta function perturbation at the centre. Some consequences of perturbation theory are discussed, as well as an introduction to (very simple) Feynman diagrams. YouTube Playlist: • PHYS3111 Quantum Mechanics © Julian Berengut, UNSW Sydney
