I know that there are multiple generic QM book recommendation questions out there, however I am looking for something with specific parameters, hence why I am posting a new question for it.
The way I learned QM in University, it was from a very "physical" point of view - in particular - representation theory and its application to QM was nonexistent there.
So, I am kind of looking for a QM book that is somewhat similar to Wald's General Relativity book in scope and style. I want something that is written for physicists by physicists (Note: I know multiple QM books by mathematicians that mainly focus on making the functional-analytic foundations of QM rigorous. I don't care about that right now, I'm fine with heuristic/incorrect formulation of spectral theory and all that), but at the same time, emphasizes overall structure and general methodology, rather than being historical, being phenomenologically/"physically" motivated or focusing too much on "understanding through applications".
In particular, I am very much interested in
representation theory - as applied to QM; Many intro books skip this altogether, but then the QFT literature assumes I know it. Also there seems to be a big divide here between physicists' and mathematicians' exposition, which further makes this difficult for me to learn.
a very systematic and elaborate treatment on angular momentum and spin; This concept always seemed so ad-hoc, unmotivated (aside from "experiments, hurr durr"), and there always seemed to me that there is a great divide between non-relativistic QM notation & approach and a systematic application of spinors that is common in the QFT/GR literature. I'd like spinors and all that properly and detailed in my QM literature.
Any book recommendations along this line are much welcome.
