Which Quantum Mechanics Book Combines Rigor and Mathematical Approach?

Click For Summary

Discussion Overview

The discussion centers around recommendations for quantum mechanics textbooks that balance rigor and a mathematical approach. Participants share their preferences based on their backgrounds in mathematics and physics, and the suitability of various texts for different levels of understanding is explored.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests starting with "Quantum Mechanics Demystified" for foundational understanding.
  • Another participant recommends "Zettili's book" as an intermediate resource for problem-solving and knowledge consolidation.
  • A further recommendation is made for "Ballentine - Quantum Mechanics A Modern Development" for a deeper understanding.
  • There is a question posed about the suitability of "Sakurai" for those who prefer mathematical rigor.
  • One participant expresses dissatisfaction with "Sakurai," stating it does not meet their standards for mathematical rigor and prefers "Ballentine" for its foundational axioms.
  • Concerns are raised about the lack of rigor in "Sakurai" compared to the participant's preferred style, which is more aligned with mathematical physics.

Areas of Agreement / Disagreement

Participants express differing opinions on the suitability of "Sakurai" for those seeking a mathematically rigorous approach, indicating a lack of consensus on its effectiveness compared to other recommended texts.

Contextual Notes

Participants' preferences are influenced by their backgrounds in mathematics and physics, and the discussion reflects varying definitions of rigor and mathematical approach in quantum mechanics literature.

Hello
I am an engineering graduate student , graduating in computer science, I wish to learn more about quantum mechanics.
I am proficient in maths and engineering maths and have a fair amount of knowledge about physics. Please suggest me some books about quantum mechanics, so I can further my knowledge about it.

bhobba what do you think of Sakurai?
 
At the level of mathematical rigor you liked in Wald's book, reading Sakurai's account of QM would be annoying.
 
Don't like Sakurai - to me it doesn't explain stuff at the level I like ie proceeding with reasonably good mathematical rigor from a small number of axioms that are reasonably well motivated. Ballentine does it with two - I won't spoil it by telling you what they are but the first is pretty much a definition of an observable that can be motivated by requiring basis independence and the second from Gleason's Theorem. When you have gone through it pop on a post and I can explain the detail.

If you like Wald (and for GR its my favorite book as well) I don't think Sakurai will appeal - it lacks rigor.

But I have to say I classify my interests as mathematical physics rather than straight physics because my background is math and computer science so texts with a more mathematical take tend to appeal.

Thanks
Bill
