Quantum Mechanics: Shankar or Cohen-Tannoudji?

Click For Summary

Discussion Overview

The discussion revolves around the comparison of two quantum mechanics textbooks, Shankar and Cohen-Tannoudji, with participants sharing their experiences and preferences. The scope includes personal opinions on the usability, content, and rigor of these texts, as well as suggestions for alternative resources.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants express a preference for Shankar, citing its quality as a first book on quantum mechanics.
  • Others find Cohen-Tannoudji's two-volume format cumbersome and criticize its indexing, though they acknowledge its unique content.
  • There is a mention of Zettili's book as a favored alternative by one participant.
  • Confusion is expressed regarding the treatment of the continuous spectrum in both books, with a request for more rigorous resources, particularly in functional analysis.
  • One participant suggests that Arno Bohm's book offers more rigor while still being accessible as a physics text.
  • Another participant recommends using a mix of textbooks, noting that even Cohen-Tannoudji does not cover all aspects of quantum mechanics comprehensively.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which textbook is better, as opinions vary widely based on personal experiences and preferences. Multiple competing views remain regarding the strengths and weaknesses of each book.

Contextual Notes

Some discussions highlight limitations in the treatment of specific topics, such as the continuous spectrum, and the varying degrees of rigor across different texts. The conversation reflects a range of assumptions about the intended audience and depth of coverage in quantum mechanics literature.

Who May Find This Useful

This discussion may be useful for students and educators in physics seeking insights on quantum mechanics textbooks and alternative resources for rigorous mathematical treatment.

Has anybody read/use both these books? Which one is "better"?
Thanks.

I've used Shankar as first book on QM, found it to be very good.
As for Cohen-Tannoudji, it was rather distasteful for me. First the monster comes in two volumes, and the indexing of the content is not convenient (look at the appendices/chapter compliments), but in terms of content its fine. Some of the topics contained, are unlikely to be found elsewhere in introductory QM books.

Another favorite of mine nowadays is Zettili's.

So which is better ? ,,,,,,,,,,,,,,,,that is for you to decide.update: there is an older thread with the same theme https://www.physicsforums.com/showthread.php?t=206371
 
The thing I find confusing is the treatment of the continuous spectrum. Am I right if I say that all these books try to give you some intuition to justify the mathematical tools they use (rules of computation using the dirac function etc). Is there any book that does this in a more rigorous way (functional analysis?)?

I've seen this book but did not use it:

If you ask me, try to use some mixtures of QM textbooks cause even the mighty Cohen-Tannoudji cannot cover everything (though it has something like ~1000 pages in total).
