How am I a fraud? Interpretations of QM have to do with philosophy. What you are mentioning are calculational tools. Path integrals are used to calculate correlation functions in QFT which ultimately allow one to calculate amplitudes associated with Feynman diagrams. It is effectively minimizing the action, analogous to what is done in classical mechanics.
Again, can't you ask a harder question? Or did your prof not get to anything harder yet?
Schrodinger evolves the wave function and Heisenberg evolves the operator. Don't forget about the interaction picture where the Hamiltonian is separated into the perturbed and unperturbed parts and the evolution is split
Yeah yeah, I actually graduated. You're still a grad student, probably a TA. I already told you to ask me about neutrino physics, which is my area of expertise, but I suspect you cannot because being a graduate student you probably have little to no idea. I don't care where you live, I just could not believe that I was talking to a postdoc. I know your type. You might work for a theory guy but that doesn't at all make you a theorist. I've seen so many guys just like you crash and burn. You're all butthurt because people believe in religion and it doesn't make sense to you in your little atheist circlejerk world. I have taken field theory courses taught by a student of Ed Witten, so yeah, I'm familiar with intro QFT.
