SUMMARY

This discussion focuses on finding accessible resources for understanding C*-algebras and the GNS construction, particularly for physicists. The primary recommendation is the two-volume work by O. Bratteli, titled "Operator Algebras and Quantum Statistical Mechanics," though it is noted that the relevant quantum mechanics content is only in the second volume. Additionally, a shorter article titled "Some Aspects of Operator Algebras in Quantum Physics" by a professor is suggested as a more digestible alternative.

PREREQUISITES
  • Basic understanding of quantum mechanics (QM)
  • Familiarity with operator algebras
  • Knowledge of functional analysis concepts
  • Ability to navigate academic literature
NEXT STEPS
  • Read "Operator Algebras and Quantum Statistical Mechanics" by O. Bratteli
  • Explore the article "Some Aspects of Operator Algebras in Quantum Physics" on arXiv
  • Study introductory texts on C*-algebras
  • Investigate the GNS construction in the context of quantum mechanics
USEFUL FOR

Physicists, mathematicians, and students interested in the intersection of quantum mechanics and functional analysis, particularly those seeking a clearer understanding of C*-algebras and their applications in quantum physics.

It is there a gentle introduction to C*-algebras and the GNS construction that is readable for physicists? You know, a text with an emphasis on QM that is formal enough to not be sloppy but not too much as to require a Ph.D in functional analysis to be read.

Just in case anyone was wondering, It seems the principal reference are the two tomes O. Bratteli, Operator Algebras and Quantum Statistical Mechanics. The problem with it is that the physics is in vol 2, so I'd have to navigate through 500 pages of abstract math just to reach some QM.

I also found an interesting article, and a much shorter read, from a professor I had in grad school
