Textbook for density matrix and trace?

Click For Summary

Discussion Overview

The discussion revolves around recommendations for quantum mechanics textbooks that cover the concepts of density matrices and traces, specifically aimed at a graduate-level understanding. The focus is on identifying suitable resources that provide detailed knowledge on these topics.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant requests recommendations for a QM textbook that details density matrices and traces.
  • Another participant asks for clarification on the level of study required for the recommendations.
  • It is suggested that Cohen-Tannoudji et al. provides a good discussion on density matrices.
  • A different participant mentions that the book by Townsend also addresses the topic of density matrices.
  • A participant confirms that Sakurai's textbook also covers density matrices and states that the previously mentioned references should be accessible at the graduate level.

Areas of Agreement / Disagreement

Participants generally agree on the suitability of Cohen-Tannoudji, Townsend, and Sakurai for graduate students, but there is no consensus on a single best recommendation.

Contextual Notes

The discussion does not specify the exact content or depth of coverage in the recommended textbooks, nor does it clarify the specific aspects of density matrices and traces that the original poster is interested in.

Who May Find This Useful

Graduate students in quantum mechanics or those seeking to deepen their understanding of density matrices and traces in quantum theory.

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.
