Quantum Textbook for density matrix and trace?

AI Thread Summary
For a graduate student seeking a quantum mechanics textbook that covers density matrices and trace, Cohen-Tannoudji et al. is highly recommended for its thorough discussion on the subject. Townsend's book is also noted for addressing these topics effectively. Additionally, Sakurai's work is mentioned as a suitable resource. All suggested texts are considered accessible for someone at the graduate level, focusing on non-relativistic quantum mechanics.

I want a QM textbook which introduces detail knowledge of density matrix and trace (i.e. the average), who can recommend one for me? Thank you.

At what level?

Cohen-Tannoudji et al. has a good discussion of the density matrix. The book by Townsend also addresses the topic.

Just non-relativity. I am a graduate student. Thank you.
 
I checked, and Sakurai also covers the topic. At your level, any of the references I have given will be accessible.

Thread 'Ashcroft and Mermin: revised edition'

Hi, I have notice that Ashcroft, Mermin and Wei worked at a revised edition of the original solid state physics book (here). The book, however, seems to be never available. I have also read that the reason is related to some disputes related to copyright. Do you have any further information about it? Did you have the opportunity to get your hands on this revised edition? I am really curious about it, also considering that I am planning to buy the book in the near future... Thanks!

Thread 'How is Jackson’s Electrodynamics taught during undergraduate?'

I’ve heard that in some countries (for example, Argentina), the curriculum is structured differently from the typical American program. In the U.S., students usually take a general physics course first, then move on to a textbook like Griffiths, and only encounter Jackson at the graduate level. In contrast, in those countries students go through a general physics course (such as Resnick-Halliday) and then proceed directly to Jackson. If the slower, more gradual approach is considered...
