Hi, I have now finished University where I took an advanced quantum mechanics module in my final undergraduate year. Having left I was quite surprised to find out that this is infact only a grounding in the subject and I would like to know more. I have covered operators and the Hamiltonian and perturbation theory but am looking for somewhere to learn more about QFT ideally. I love the Leonard Susskind lectures on youtube/itunes and was wondering if there might be any similar resources I could use to teach myself more. Also any suggestions of books that are good to work with would be much appreciated. Many Thanks!
