I just finished a first course in quantum mechanics based on Griffiths' textbook. I have to take an advanced qm course next sem which starts in Feb. I was planning to do some reading by then mostly on some specific topics like mathematical formalism of QM, spin and angular momenta, and identical particles. I am thinking of buying a book (or two) for this and for the next sem. The prescribed textbooks for this course are 1. J. J. Sakurai : Modern Quantum Mechanics (Addison Wesley) 2. L. I. Schiff : Quantum Mechanics (Mcgraw-Hill) 3. Cohen-Tannoudji : Quantum Mechanics (John Wiley and Sons) 4. E. Merzbacher : Quantum Mechanics (John Wiley and Sons) 5. K. Gottfried and T-M Yan: Quantum Mechanics : Fundamentals (Springer) And I am familiar with a few other books like Shankar and Ballentine. So I would like to know which of these books have a good exposition of the topics I mentioned? I need a book which is precise yet comprehensible, has commonly used notation and at least a few exercise problems. They need not be from the list I mentioned, but at least at the same level.
