Anyone read the book Advanced Quantum Physics by Hans Paar ? Is this somewhat analogous to Sakurai's advanced quantum mechanics? If anyone used it, can youcomment on what you used it for (e.g. was it a bridge between QM and QFT)? I happened to see this book on amazon and from the excerpt, it looks like an interesting material and quite inexpensive. It also seems to have been written for undergraduates. Please share if you have any opinions about this book. Thank you!
