I'm trying to get a handle on the rotation group in quantum mechanics. Does anyone have suggestions or links to clear and consise statements of this material. I am looking for a level of about Sakurai.

Thanks
 
Physics news on Phys.org
Weyl's & Wigner's books were the first to deal with group theory in QM.

There's no better treatment than the one in Sakurai.Close come R.Newton,A.Messiah & Davydov.

My advice is go for the best.

Daniel.
 
I would highly reccomend, also, Edmonds, Angular Momentum in Quantum Mechanics, the bible for many of us older types.

I agree with Reilly and dextercioby,

Besides if you are interested in a little summary, just check out the 'how grouptheory works'-entry in my journal : https://www.physicsforums.com/journal.php?s=&journalid=13790&action=view

In addition, try Tinkhams book on Group Theory along with Wu-Ki Tungs, both are excellent.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
