Fourth lecture Advanced Quantum Mechanics
We got through the formal part of the course – and started enjoying the examples! Magnetism, the puzzle of centuries:) I’ve put quite some new material I’ve never taught before. This was about magnons and other excitations in a magnet. I was not sure I could do it in time from the first attempt and warned the students in the beginning that perhaps I will have to skip this part.
Well, it went better than expected, though I had to skip a couple of slides. Moreover, it looks I could catch an attention provoking questions. The idea of the energy splitting of two spin subbands has spontaneously originated in the audience, a way before I was planning to talk about it. Nice 🙂
Anyway, there is room for improvement for the next time.
